This was a descriptive longitudinal study, based on cases of deep vein thrombosis recorded between 1 January 2015 and 30 September 2018, in the cardiology and internal medicine department of the Brazzaville University Hospital Centre. During the study period, 4678 patients were hospitalized, including 52 with DVT. Thirty-three were reassessed. The frequency of DVT was 1.1% and the average hospitalization rate was 13.9 cases/year. The 33 patients were divided into 20 women and 13 men (sex ratio: 0.65). The mean age of the patients was 51.4 ± 17.8 years (extremes: 16 and 85 years). The main aetiological factors were cancer (19.1%), sickle cell disease (3%) and HIV immunosuppression (3%). The predominant risk factors were: prolonged immobilization (42.9%), pregnancy, long travel and obesity in the same number of cases (n = 3, i.e. 14.2%). The DVT involved the left pelvic limb in 75.8% of cases. Anticoagulants were administered in all patients, and compression stockings were worn in 97% of cases. The mean time to re-evaluation was 10.9 ± 9.4 months (extremes: three and 35 months). The mean measurements of the limb where the thrombosis had occurred at diagnosis and reassessment showed a significant difference. Venous Doppler showed compressible veins (60.6%), varicosities (36.3%), incompressible veins (30.3%) and thrombus (21.2%). Complications were: post-phlebitic disease (42.4%), death (21.2%), pulmonary embolism (18.2%), recurrence (18.2%). The DVT remains relatively rare, and its conventional therapeutic management is satisfactory. Systematic venous Doppler ultrasound reassessment should enable patients at risk of recurrence to be identified.展开更多

Our goal is to improve both awareness and early diagnosis and treatment of rare clinical diseases. Furthermore, we aim to examine advancements in the diagnosis and treatment of deep vein thrombosis. Method: The clinical information of patients with PCD received in 2022 was subject to retrospective analysis. The author conducted a search of 191 publications with a focus on PCD, from January 2010 to July 2022, from databases such as the China National Knowledge Infrastructure (CNKI), Wanfang Data, PubMed, etc. The results were used to summarize the examinations, diagnostic criteria, and treatment progress of PCD patients. Additionally, the author conducted another search using keywords such as “Venous thromboembolism” and “Anticoagulant drugs” to summarize research progress in anticoagulant drugs and the treatment of VTE. The search was limited to relevant. Outcome: Six months prior to admission, the patient, a 68-year-old female, developed sunken edema and cyanosis in both her lower extremities and was diagnosed with lower extremity deep vein thrombosis complicated by PCD, lower extremity ischemic necrosis, and septicemia. This diagnosis was made using a combination of CT and lower extremity vascular ultrasound-related examinations, as well as a significantly elevated D-dimer value. Despite active treatment and aggressive measures, such as anti-infection, organ function maintenance, anticoagulation, and improvement of microcirculatory disorders, the patient’s family declined corresponding surgical treatment and interventional surgery for the lower extremity due to objective factors, and the patient ultimately succumbed to her illness. The clinical characteristics of this patient were similar to those of the 14 cases of PCD reported by Xie Fei et al. in 2022. Conclusion: For patients with malignancy, it is crucial to start anticoagulation and physical prevention of DVT early on. Patients with DVT complicated by PCD have a variety of surgical options available to them, including surgical embolization or PMT (percutaneous mechanical thrombus ablation), CDT (catheter contact thrombolysis), and fascial ventriculotomy decompression [1]. Additionally, it may be necessary to place an inferior venous filter. Although the incidence of this disease is low accounting for approximately 5% of all patients with iliofemoral deep vein thrombosis [2], the prognosis is poor, as the mortality rate can reach up to 40% - 60% due to venous gangrene, with an overall mortality rate of 20% - 40% [3]. To increase the survival rate, it is important to diagnose and treat this disease as early as possible.展开更多

Venous thromboembolic disease (MVTE) and cancer are two frequently entangled pathologies. Here we report the diagnosis of deep vein thrombosis that discovered prostate cancer in an 88-year-old Guinean man. On clinical examination, there was a painful and hot swelling of the right leg, an absence of sloshing of the calf, a positive sign of Homans. The digital rectal examination revealed an enlarged prostate with an irregular surface. Cardiopulmonary auscultation was normal. The electrocardiogram showed a regular sinus rhythm at 65 cycles/min, with no sign of enlarged cavities or conduction disturbance.

However, immunocompromised hosts and older adults with complex medical conditions may develop a complicated form of bacteraemia, with a high mortality rate involving extra-intestinal foci of infection and mycotic aneurysms. We report the case of a 61-year-old man with poorly controlled diabetes mellitus, hypertension, dyslipidaemia, and congestive heart failure, who presented with unilateral left lower limb swelling, extensive deep vein thrombosis, and concomitant Salmonella bacteraemia. An oral anticoagulant and intravenous antibiotic therapy were initiated. Although the patient remained haemodynamically stable, he complained of constant left lower limb weakness and lower back pain. A computed tomography angiography scan of the thorax and abdomen revealed saccular aneurysms with contained hematoma of the left common iliac artery. The oral anticoagulant was discontinued, and an inferior vena cava filter was inserted as part of the venous thrombosis management. The patient was offered aorto-uni-iliac endovascular aneurysm repair and received intravenous antibiotic therapy, postoperatively, for six weeks. The postoperative blood cultures remained negative, and he was discharged with a course of ciprofloxacin administered orally. However, three months after the surgery, the patient died of recurrent septicaemia. This case illustrates the importance of remaining vigilant for potential endovascular complications of Salmonella bacteraemia, such as mycotic aneurysms and deep vein thrombosis, among high-risk patients. Further, this case highlights the challenges of eliminating Salmonella bacteraemia and its related complications, albeit treating it with both a prolonged course of medical therapy and surgical intervention.展开更多

Epidemiological data are scarce in Africa. The objective of this work was to describe the prevalence, risk factors and treatment of deep venous thrombosis (DVT) in Ziguinchor. <strong>Methodology:</strong> This was a retrospective study carried out at the Ziguinchor Peace Hospital from January 1, 2016 to June 30, 2020. We included in the study all patients of both sexes, aged at least 18 years and hospitalized with DVT of the lower limb confirmed by venous Doppler ultrasound. <strong>Results:</strong> A total of 64 patients were hospitalized for DVT of the lower limbs during the study, for a hospital prevalence of 3.9%. The average age of the patients was 53 years (±17.6). A female predominance was noted with an M/F sex ratio of 0.7. The main risk factors found were the age ≥ 60 years (36%) and infectious pathologies (17%). Clinical signs were dominated by lower limb pain (93.8%) and lower limb edema (92%). The lower limbs’ venous Doppler ultrasound showed a predominance of thrombosis in the left lower limb (56%). The femoral vein was the most affected in 90% of cases. The patients had all benefited from an anticoagulant treatment mainly by a low molecular weight heparin relayed from the 1st day by an antivitamin K that was acenocoumarol in 97% of the cases. The average length of hospitalization was 10 days. The complications found were pulmonary embolism (8%) and accident with anticoagulants (3%). Hospital mortality was 6%. The average cost of care was 164.000 CFA francs. <strong>Conclusion:</strong> DVT is a multifactorial pathology;its treatment requires the control of risk factors. In our study, it was more frequent in the elderly.展开更多

The patients in the control group were treated with subcutaneous injection of low-molecular-weight heparin calcium, and those in the observation group were additionally given Danshen Injection and TCM decoction. The differences between two groups in occurrence rate, medication time, therapeutic effects,recurrence rate of thrombosis, activated partial thromboplastin time(APTT), and prothrombin time(PT) were compared.RESULTS: The occurrence rate of DVT in observation group(4.65%, 2/43) was lower than that in control group(27.91%,12/43)(P<0.05). The medication time of observation group was(6.15±2.94) d, shorter than(9.76±3.12) d in the control group(P<0.05). In observation group, 2 cases of DVT were cured(2/2); in the control group, 9 cases presented therapeutic effects and the total effective rate was 75.00%(9/12). The improvement of APTT and PT in the observation group was better than that in the control group(P<0.05).CONCLUSION: Integrative TCM decoction plus low-molecularweight heparin calcium is superior to applicaton of low-molecularweight heparin calcium alone in reducing and treating DVT in the postoperative patients with lower limb fracture.展开更多
文摘Upper extremity deep vein thrombosis(UEDVT)is less common than lower extremity DVT but is a cause of significant morbidity and mortality in intensive care unit patients.Increasing cancer incidence,prolonged life expectancy and increasing use of intravascular catheters and devices has led to an increased incidence of UEDVT.It is also associated with high rates of complications like pulmonary embolism,post-thrombotic syndrome and recurrent thrombosis.Clinical prediction scores and D-dimer may not be as useful in identifying UEDVT;hence,a high suspicion index is required for diagnosis.Doppler ultrasound is commonly employed for diagnosis,but other tests like computed tomography and magnetic resonance imaging venography may also be required in some patients.Contrast venography is rarely used in patients with clinical and ultrasound findings discrepancies.Anticoagulant therapy alone is sufficient in most patients,and thrombolysis and surgical decompression is seldom indicated.The outcome depends on the cause and underlying comorbidities.
文摘BACKGROUND Deep vein thrombosis(DVT)of the lower extremity is one of the most common postoperative complications,especially after craniocerebral surgery.DVT may lead to pulmonary embolism,which has a devastating impact on patient prognosis.This study aimed to investigate the incidence and risk factors of DVT in the lower limbs following craniocerebral surgery.AIM To identify independent risk factors for the development of postoperative DVT and to develop an effective risk prediction model.METHODS The demographic and clinical data of 283 patients who underwent craniocerebral surgery between December 2021 and December 2022 were retrospectively analyzed.The independent risk factors for lower extremity DVT were identified by univariate and multivariate analyses.A nomogram was created to predict the likelihood of lower extremity DVT in patients who had undergone craniocerebral surgery.The efficacy of the prediction model was determined by receiver operating characteristic curve using the probability of lower extremity DVT for each sample.RESULTS Among all patients included in the analysis,47.7%developed lower extremity DVT following craniocerebral surgery.The risk of postoperative DVT was higher in those with a longer operative time,and patients with intraoperative intermittent pneumatic compression were less likely to develop postoperative DVT.CONCLUSION The incidence of lower extremity DVT following craniocerebral surgery is significant,highlighting the importance of identifying independent risk factors.Interventions such as the use of intermittent pneumatic compression during surgery may prevent the formation of postoperative DVT.
文摘The aim of this study was to describe the characteristics of patients with deep vein thrombosis (DVT) of the pelvic limbs at the time of diagnosis, and their course after hospitalization, in order to improve the management of DVT in our context. This was a descriptive longitudinal study, based on cases of deep vein thrombosis recorded between 1 January 2015 and 30 September 2018, in the cardiology and internal medicine department of the Brazzaville University Hospital Centre. During the study period, 4678 patients were hospitalized, including 52 with DVT. Thirty-three were reassessed. The frequency of DVT was 1.1% and the average hospitalization rate was 13.9 cases/year. The 33 patients were divided into 20 women and 13 men (sex ratio: 0.65). The mean age of the patients was 51.4 ± 17.8 years (extremes: 16 and 85 years). The main aetiological factors were cancer (19.1%), sickle cell disease (3%) and HIV immunosuppression (3%). The predominant risk factors were: prolonged immobilization (42.9%), pregnancy, long travel and obesity in the same number of cases (n = 3, i.e. 14.2%). The DVT involved the left pelvic limb in 75.8% of cases. Anticoagulants were administered in all patients, and compression stockings were worn in 97% of cases. The mean time to re-evaluation was 10.9 ± 9.4 months (extremes: three and 35 months). The mean measurements of the limb where the thrombosis had occurred at diagnosis and reassessment showed a significant difference. Venous Doppler showed compressible veins (60.6%), varicosities (36.3%), incompressible veins (30.3%) and thrombus (21.2%). Complications were: post-phlebitic disease (42.4%), death (21.2%), pulmonary embolism (18.2%), recurrence (18.2%). The DVT remains relatively rare, and its conventional therapeutic management is satisfactory. Systematic venous Doppler ultrasound reassessment should enable patients at risk of recurrence to be identified.
文摘Goal: The purpose of this research is to analyze the clinical characteristics, diagnosis, treatment, and prognosis of critical care patients with phlegmasia cerulea dolens (PCD) caused by deep vein thrombosis. Our goal is to improve both awareness and early diagnosis and treatment of rare clinical diseases. Furthermore, we aim to examine advancements in the diagnosis and treatment of deep vein thrombosis. Method: The clinical information of patients with PCD received in 2022 was subject to retrospective analysis. The author conducted a search of 191 publications with a focus on PCD, from January 2010 to July 2022, from databases such as the China National Knowledge Infrastructure (CNKI), Wanfang Data, PubMed, etc. The results were used to summarize the examinations, diagnostic criteria, and treatment progress of PCD patients. Additionally, the author conducted another search using keywords such as “Venous thromboembolism” and “Anticoagulant drugs” to summarize research progress in anticoagulant drugs and the treatment of VTE. The search was limited to relevant. Outcome: Six months prior to admission, the patient, a 68-year-old female, developed sunken edema and cyanosis in both her lower extremities and was diagnosed with lower extremity deep vein thrombosis complicated by PCD, lower extremity ischemic necrosis, and septicemia. This diagnosis was made using a combination of CT and lower extremity vascular ultrasound-related examinations, as well as a significantly elevated D-dimer value. Despite active treatment and aggressive measures, such as anti-infection, organ function maintenance, anticoagulation, and improvement of microcirculatory disorders, the patient’s family declined corresponding surgical treatment and interventional surgery for the lower extremity due to objective factors, and the patient ultimately succumbed to her illness. The clinical characteristics of this patient were similar to those of the 14 cases of PCD reported by Xie Fei et al. in 2022. Conclusion: For patients with malignancy, it is crucial to start anticoagulation and physical prevention of DVT early on. Patients with DVT complicated by PCD have a variety of surgical options available to them, including surgical embolization or PMT (percutaneous mechanical thrombus ablation), CDT (catheter contact thrombolysis), and fascial ventriculotomy decompression [1]. Additionally, it may be necessary to place an inferior venous filter. Although the incidence of this disease is low accounting for approximately 5% of all patients with iliofemoral deep vein thrombosis [2], the prognosis is poor, as the mortality rate can reach up to 40% - 60% due to venous gangrene, with an overall mortality rate of 20% - 40% [3]. To increase the survival rate, it is important to diagnose and treat this disease as early as possible.
文摘BACKGROUND:To investigate the clinical effectiveness of a pneumatic compression device(PCD)combined with low-molecular-weight heparin(LMWH)for the prevention and treatment of deep vein thrombosis(DVT)in trauma patients.METHODS:This study retrospectively analyzed 286 patients with mild craniocerebral injury and clavicular fractures admitted to our department from January 2016 to February 2020.Patients treated with only LMWH served as the control group,and patients treated with a PCD combined with LMWH as the observation group.The incidence of DVT,postoperative changes in the visual analogue scale(VAS)score,and coagulation function were observed and compared between the two groups.Excluding the influence of other single factors,binary logistic regression analysis was used to evaluate the use of a PCD in the patient’s postoperative coagulation function.RESULTS:After excluding 34 patients who did not meet the inclusion criteria,252 patients were were included.The incidence of DVT in the observation group was significantly lower than that in the control group(5.6%vs.15.1%,χ^(2)=4.605,P<0.05).The postoperative VAS scores of the two groups were lower than those before surgery(P<0.05).The coagulation function of the observation group was significantly higher than that of the control group,with a better combined anticoagulant effect(P<0.05).There were no significant differences between the two groups in preoperative or postoperative Glasgow Coma Scale scores,intraoperative blood loss,postoperative infection rate,or length of hospital stay(P>0.05).According to logistic regression analysis,the postoperative risk of DVT in patients who received LMWH alone was 1.764 times that of patients who received LMWH+PCD(P<0.05).The area under the receiver operating characteristic(AUROC)curve of partial thromboplastin time(APTT)and platelet(PLT)were greater than 0.5,indicating that they were the influence indicators of adding PCD to prevent DVT.Excluding the influence of other variables,LMWH+PCD effectively improved the coagulation function of patients.CONCLUSIONS:Compared with LMWH alone,LMWH+PCD could improve blood rheology and coagulation function in patients with traumatic brain injury and clavicular fracture,reduce the incidence of DVT,shorten the length of hospital stay,and improve the clinical effectiveness of treatment.

文摘BACKGROUND The artificial liver support system(ALSS)is an effective treatment method for liver failure,but it requires deep venous intubation and long-term indwelling catheterization.However,the coagulation mechanism disorder of basic liver failure diseases,and deep venous thrombosis(DVT)often occur.AIM To evaluate the risk factors for DVT following use of an ALSS and establish a risk assessment score.METHODS This study was divided into three stages.In the first stage,the risk factors for DVT were screened and the patient data were collected,including ALSS treatment information;biochemical indices;coagulation and hematology indices;complications;procoagulant use therapy status;and a total of 24 indicators.In the second stage,a risk assessment score for DVT after ALSS treatment was developed.In the third stage,the DVT risk assessment score was validated.RESULTS A total of 232 patients with liver failure treated with ALSS were enrolled in the first stage,including 12 with lower limb DVT.Logistic regression analysis showed that age[odds ratio(OR),1.734;P=0.01],successful catheterization time(OR,1.667;P=0.005),activity status(strict bed rest)(OR,3.049;P=0.005),and D-dimer level(≥500 ng/mL)(OR,5.532;P<0.001)were independent risk factors for DVT.We then established a scoring system for risk factors.In the validation group,a total of 213 patients with liver failure were treated with ALSS,including 14 with lower limb DVT.When the cutoff value of risk assessment was 3,the specificity and sensitivity of the risk assessment score were 88.9%and 85.7%,respectively.CONCLUSION A simple risk assessment scoring system was established for DVT patients with liver failure treated with ALSS and was verified to have good sensitivity and specificity.
文摘BACKGROUND Abnormalities of the inferior vena cava(IVC)are uncommon,and in many cases they are asymptomatic.Even so,it is vital that clinicians be aware of such anomalies prior to surgery in affected individuals.In the present report,we describe a rare anatomical variation of the IVC.CASE SUMMARY A 66-year-old male was admitted to the hospital due to deep vein thrombosis of the right lower extremity.Upon contrast-enhanced computed tomography imaging,we found that this patient presented with a case of left-sided IVC draining into the hemiazygos vein,while his hepatic vein was directly draining into the atrium.CONCLUSION Cases of left-sided IVC can increase patient susceptibility to thromboembolism owing to the resultant changes in blood flow and/or associated vascular compression.

文摘BACKGROUND Deep vein thrombosis(DVT)may cause pulmonary embolus,leading to late deaths.The systemic inflammatory and hypercoagulable state of moderate and severe acute pancreatitis(non-mild acute pancreatitis,NMAP)patients may contribute to the development of venous thromboembolism.Accurate prediction of DVT is conducive to clinical decisions.AIM To develop and validate a potential new prediction nomogram model for the occurrence of DVT in NMAP.METHODS NMAP patient admission between 2013.1.1 and 2018.12.31 at the West China Hospital of Sichuan University was collected.A total of 220 patients formed the training set for nomogram development,and a validation set was constructed using bootstrapping with 100 resamplings.Univariate and multivariate logistic regression analyses were used to estimate independent risk factors associated with DVT.The independent risk factors were included in the nomogram.The accuracy and utility of the nomogram were evaluated by calibration curve and decision curve analysis,respectively.RESULTS A total of 220 NMAP patients over 60 years old were enrolled for this analysis.DVT was detected in 80(36.4%)patients.The final nomogram included age,sex,surgery times,D-dimer,neutrophils,any organ failure,blood culture,and classification.This model achieved good concordance indexes of 0.827(95%CI:0.769-0.885)and 0.803(95%CI:0.743-0.860)in the training and validation sets,respectively.CONCLUSION We developed and validated a prediction nomogram model for DVT in older patients with NMAP.This may help guide doctors in making sound decisions regarding the administration of DVT prophylaxis.
文摘Objective:To investigate and analyze the long-term clinical effects of acupoint application combined with pneumatic compression therapy in the prevention of deep venous thrombosis after hip fracture surgery among the elderly.Methods:Sixty elderly patients who had undergone hip fracture surgery from February 2021 to February 2022 were selected as the research subjects.The patients were divided into two groups via drawing lots.Both the groups received nursing care,but the patients in the observation group were treated with TCM acupoint application combined with pneumatic compression therapy,whereas the control group received pneumatic compression therapy.The evaluation indicators included the patients’quality of life and complications.Results:The incidence of lower extremity deep vein thrombosis in the observation group was more than twice(0.3%),whereas the incidence of lower extremity complications in the control group was more than 6 times(20%).There was a significant difference between the two groups(p<0.05).Conclusion:Traditional Chinese medicine acupoint application combined with pneumatic compression therapy is beneficial for the prevention of postoperative lower extremity deep vein thrombosis among elderly patients.In addition,the patients’overall quality-of-life scores in both physiological and psychological aspects improved significantly,which carries significant clinical reference value.

文摘BACKGROUND The contradictory process of coagulation and anticoagulation maintains normal physiological function,and platelets(PLTs)play a key role in hemostasis and bleeding.When severe thrombocytopenia and deep vein thrombosis(DVT)occur simultaneously,the physician will be confronted with a great challenge,especially when interventional thrombectomy fails.CASE SUMMARY We describe a 52-year-old woman who suffered from myelodysplastic syndrome with severe thrombocytopenia and protein S deficiency with right lower extremity DVT.In this patient,the treatment of DVT was associated with numerous contradictions due to severe thrombocytopenia,especially when interventional thrombectomy was not successful.Fortunately,fondaparinux sodium effectively alleviated the thrombus status of the patient and gradually decreased the D-dimer level.In addition,no increase in bleeding was noted.The application of eltrombopag stimulated the maturation and differentiation of megakaryocytes and increased the peripheral blood PLT count.The clinical symptoms of DVT in the right lower extremities in this patient significantly improved.The patient resumed daily life activities,and the treatment effects were independent of PLT transfusion.CONCLUSION This is a contradictory and complex case,and fondaparinux sodium and eltrombopag may represent a good choice for the treatment of DVT in patients with severe thrombocytopenia.

文摘TPostoperative deep venous thrombosis is a more common clinical problem,and its preventive significance is greater than treatment.Compared with drug therapy,stress therapy has a definite effect and a wider range of applications,which is of great significance in clinical application.This article summarizes the relevant guidelines and recommendations for the prevention of deep vein thrombosis after surgery,the classification of specific treatment methods,the application situation and precautions in various types of surgery.
文摘<strong>Introduction:</strong><span style="font-family:Verdana;"> Deep vein thrombosis is a frequent disease, its origin is most often multifactorial. Venous thromboembolic disease (MVTE) and cancer are two frequently entangled pathologies. Here we report the diagnosis of deep vein thrombosis that discovered prostate cancer in an 88-year-old Guinean man. On clinical examination, there was a painful and hot swelling of the right leg, an absence of sloshing of the calf, a positive sign of Homans. The digital rectal examination revealed an enlarged prostate with an irregular surface. Cardiopulmonary auscultation was normal. The electrocardiogram showed a regular sinus rhythm at 65 cycles/min, with no sign of enlarged cavities or conduction disturbance. Venous Doppler ultrasound of the lower limbs showed the presence of an extensive acute deep venous thrombosis of the right sural vein extended to the popliteal and to the homolateral deep femoral.

文摘Salmonella, a food-borne pathogen, can cause mild self-limiting gastroenteritis. However, immunocompromised hosts and older adults with complex medical conditions may develop a complicated form of bacteraemia, with a high mortality rate involving extra-intestinal foci of infection and mycotic aneurysms. We report the case of a 61-year-old man with poorly controlled diabetes mellitus, hypertension, dyslipidaemia, and congestive heart failure, who presented with unilateral left lower limb swelling, extensive deep vein thrombosis, and concomitant Salmonella bacteraemia. An oral anticoagulant and intravenous antibiotic therapy were initiated. Although the patient remained haemodynamically stable, he complained of constant left lower limb weakness and lower back pain. A computed tomography angiography scan of the thorax and abdomen revealed saccular aneurysms with contained hematoma of the left common iliac artery. The oral anticoagulant was discontinued, and an inferior vena cava filter was inserted as part of the venous thrombosis management. The patient was offered aorto-uni-iliac endovascular aneurysm repair and received intravenous antibiotic therapy, postoperatively, for six weeks. The postoperative blood cultures remained negative, and he was discharged with a course of ciprofloxacin administered orally. However, three months after the surgery, the patient died of recurrent septicaemia. This case illustrates the importance of remaining vigilant for potential endovascular complications of Salmonella bacteraemia, such as mycotic aneurysms and deep vein thrombosis, among high-risk patients. Further, this case highlights the challenges of eliminating Salmonella bacteraemia and its related complications, albeit treating it with both a prolonged course of medical therapy and surgical intervention.
文摘Objective:To explore and analyze on how to prevent and treat deep vein thrombosis of the lower limbs in patients with complications after orthopedic trauma surgery.Methods:The research patients were selected from the cases of surgical treatment of orthopedic trauma in the hospital during the past two years,and a total of 58 patients were selected.The patients were randomly divided into two groups,with 29 patients in the control group treated with conventional clinical methods;and the other 29 patients were assigned to the experimental group,where targeted preventive and therapeutic measures were administered.During the research,the number of complications of postoperative deep vein thrombosis of the lower limbs and the corresponding treatment efficacy were compared between the two groups of patients.Results:According to the results of clinical experiments,the probability of patients in the experimental group suffering from deep vein thrombosis of the lower limbs after surgery was significantly lower than that of the control group(P<0.05);in addition,when complications of deep venous thrombosis of the lower limbs occurred,the treatment efficacy of the patients in the experimental group was 96.55%,and the treatment efficacy of the patients in the control group was 82.76%.There was a significant difference between the two groups(P<0.05).Conclusion:Through clinical experiments to study and analyze the prevention and treatment measures of deep vein thrombosis in patients with complications after orthopedic trauma surgery,this research proves that active and comprehensive preventive and treatment measures can effectively reduce the number of complications and improve surgery treatment efficacy.

文摘This study was carried out explore the mechanism underlying the inhibition of platelet activation by kelp fucoidans in deep venous thrombosis(DVT)mouse.In the control and sham mice,the walls of deep vein were regular and smooth with intact intima,myometrium and adventitia.The blood vessel was wrapped with the tissue and there was no thrombosis in the lumen.In the DVT model,the wall was uneven with thicken intima,myometrium and adventitia.After treated with fucoidans LF1 and LF2,the thrombus was dissolved and the blood vessel was recanalized.Compared with the control group,the ROS content,ET-1 and VWF content and the expression of PKC-βand NF-κB in the model were significantly higher(P<0.05);these levels were significantly reduced following treatments with LF2 and LF1.Compared with H_(2)O_(2)treated-HUVECs,combined LF1 and LF2 treatment resulted in significant decrease in the expression of PKC-β,NF-κB,VWF and TM protein(P<0.05).It is clear that LF1 and LF2 reduces DVT-induced ET-1,VWF and TM expressions and production of ROS,thus inhibiting the activation of PKC-β/NF-κB signal pathway and the activation of coagulation system and ultimately reducing the formation of venous thrombus.

文摘Deep venous thrombosis(DVT)poses a major challenge to public health worldwide.Endothelial cell injury evokes inflammatory and oxidative responses that contribute to thrombus formation.Tea polyphenol(TP)in the form of epigallocatechin-3-gallate(EGCG)has anti-inflammatory and oxidative effect that may ameliorate DVT.However,the precise mechanism remains incompletely understood.The current study was designed to investigate the anti-DVT mechanism of EGCG in combination with warfarin(an oral anticoagulant).Rabbits were randomly divided into five groups.A DVT model of rats was established through ligation of the inferior vena cava(IVC)and left common iliac vein,and the animals were orally administered with EGCG,warfarin,or vehicle for seven days.In vitro studies included pretreatment of human umbilical vein endothelial cells(HUVECs)with different concentrations of EGCG for 2 h before exposure to hydrogen peroxide.Thrombus weight and length were examined.Histopathological changes were observed by hematoxylin-eosin staining.Blood samples were collected for detecting coagulation function,including thrombin and prothrombin times,activated partial thromboplastin time,and fibrinogen levels.Protein expression in thrombosed IVCs and HUVECs was evaluated by Western blot,immunohistochemical analysis,and/or immunofluorescence staining.RT-qPCR was used to determine the levels of AGTR-1 and VEGF mRNA in IVCs and HUVECs.The viability of HUVECs was examined by CCK-8 assay.Flow cytometry was performed to detect cell apoptosis and ROS generation was assessed by 2′,7ʹ-dichlorofluorescein diacetate reagent.In vitro and in vivo studies showed that EGCG combined with warfarin significantly reduced thrombus weight and length,and apoptosis in HUVECs.Our findings indicated that the combination of EGCG and warfarin protects HUVECs from oxidative stress and prevents apoptosis.However,HIF-1αsilencing weakened these effects,which indicated that HIF-1αmay participate in DVT.Furthermore,HIF-1αsilencing significantly up-regulated cell apoptosis and ROS generation,and enhanced VEGF expression and the activation of the PI3K/AKT and ERK1/2 signaling pathways.In conclusion,our results indicate that EGCG combined with warfarin modifies HIF-1αand VEGF to prevent DVT in rabbits through anti-inflammation via the PI3K/AKT and ERK1/2 signaling pathways.

文摘Objective:To evaluate the efficacy of deep vein thrombosis(DVT)prevention among realworld surgical inpatients who received panax notoginseng saponins(PNS)combined with low-molecularweight heparin(LMWH).Methods:A prospective cohort study was conducted among surgical patients between January 2016 and November 2018 in Xuanwu Hospital,Capital Medical University,Beijing,China.Participants received LMWH alone or PNS combined with LMWH for preventing DVT.The primary outcome was incidence of lower extremity DVT,which was screened once a week.Participants in the LMWH group were given LMWH(enoxaparin)via hypodermic injection,4000-8000 AxalU once daily.Participants in the exposure group received PNS(Xuesaitong oral tablets,100 mg,3 times daily)combined with LMWH given the same as LMWH group.Results:Of the 325 patients screened for the study,281 participants were included in the final analysis.The cohort was divided into PNS+LMWH group and LMWH group with 134 and 147 participants,respectively.There was a significant difference of DVT incidence between two groups(P=0.01),with 21(15.7%)incident DVT in the PNS+LMWH group,and 41(27.9%)incident DVT in the LMWH group.Compared with participants without DVT,the participants diagnosed with DVT were older and had higher D-dimer level.The multivariate logistic regression moclel showed a significant lower risk of incident DVT among participants in the PNS+LMWH group compared with the LMWH group(odds ratio 0.46,95%confidence interval,0.25-0.86).There were no significant differences in thromboelaslography values(including R,K,Angle,and MA)and differences in severe bleeding between two groups.No symptomatic pulmonary embolism occurred during the study.Conclusion:Combined application of PNS and LMWH can effectively reduce the incidence of DVT among surgical inpatients compared with LMWH monotherapy,without increased risk of bleeding.
文摘<strong>Context and Objectives:</strong> Deep vein thrombosis (DVT) is a potentially serious affection because it can be complicated by life-threatening pulmonary embolism. Epidemiological data are scarce in Africa. The objective of this work was to describe the prevalence, risk factors and treatment of deep venous thrombosis (DVT) in Ziguinchor. <strong>Methodology:</strong> This was a retrospective study carried out at the Ziguinchor Peace Hospital from January 1, 2016 to June 30, 2020. We included in the study all patients of both sexes, aged at least 18 years and hospitalized with DVT of the lower limb confirmed by venous Doppler ultrasound. <strong>Results:</strong> A total of 64 patients were hospitalized for DVT of the lower limbs during the study, for a hospital prevalence of 3.9%. The average age of the patients was 53 years (±17.6). A female predominance was noted with an M/F sex ratio of 0.7. The main risk factors found were the age ≥ 60 years (36%) and infectious pathologies (17%). Clinical signs were dominated by lower limb pain (93.8%) and lower limb edema (92%). The lower limbs’ venous Doppler ultrasound showed a predominance of thrombosis in the left lower limb (56%). The femoral vein was the most affected in 90% of cases. The patients had all benefited from an anticoagulant treatment mainly by a low molecular weight heparin relayed from the 1st day by an antivitamin K that was acenocoumarol in 97% of the cases. The average length of hospitalization was 10 days. The complications found were pulmonary embolism (8%) and accident with anticoagulants (3%). Hospital mortality was 6%. The average cost of care was 164.000 CFA francs. <strong>Conclusion:</strong> DVT is a multifactorial pathology;its treatment requires the control of risk factors. In our study, it was more frequent in the elderly.

文摘OBJECTIVE: To investigate the combined effect of Traditional Chinese Medicine(TCM) decoction and low-molecular-weight heparin calcium on deep vein thrombosis(DVT) induced by surgery in patients with lower limb fracture.METHODS: Totally 86 hospitalized patients with DVT after surgery of lower limb fracture between September 2012 and January 2015 were recruited and randomly divided into control group and observation group, 43 cases in each group. The patients in the control group were treated with subcutaneous injection of low-molecular-weight heparin calcium, and those in the observation group were additionally given Danshen Injection and TCM decoction. The differences between two groups in occurrence rate, medication time, therapeutic effects,recurrence rate of thrombosis, activated partial thromboplastin time(APTT), and prothrombin time(PT) were compared.RESULTS: The occurrence rate of DVT in observation group(4.65%, 2/43) was lower than that in control group(27.91%,12/43)(P<0.05). The medication time of observation group was(6.15±2.94) d, shorter than(9.76±3.12) d in the control group(P<0.05). In observation group, 2 cases of DVT were cured(2/2); in the control group, 9 cases presented therapeutic effects and the total effective rate was 75.00%(9/12). The improvement of APTT and PT in the observation group was better than that in the control group(P<0.05).CONCLUSION: Integrative TCM decoction plus low-molecularweight heparin calcium is superior to applicaton of low-molecularweight heparin calcium alone in reducing and treating DVT in the postoperative patients with lower limb fracture.
