This has been called "Interventionalogy", "interventional medicine(IM)", or simply Intervention by our team,and "Interventional Radiology" is used no more. It has even been given the name "Third clinical Medicine" by us. Chinese intervention has established an independent association for interventional doctors, as well as independent interventional societies in many provinces. The national interventional society will likely be set up at some point in time. Chinese interve ntion has set up their own clinical wards, with much attention paid to a clinical, professional, and normalized direction for development, and established special nursing units. According to us, turf battle is meaningless. "The Third clinical Medicine" belongs to all human beings. It could also be predicted that interventional history will follow the same evolutionary rule as other disciplines, i.e., "long divided, must unite; long united, must divide".展开更多

METHODS: A total of 124 patients, who needed to undergo coronary intervention in our hospital, were randomly divided into the fine group and the combined group, with 62 patients in each group. The two groups of patients were enrolled in the PCI routine nursing procedure, in which the fine group was given refined nursing, and the joint group, based on that, added the traditional Chinese medicine nursing. The self-management (self-management scale of coronary heart disease), self-efficacy (self-efficacy scale of coronary heart disease), quality of life score (Seattle angina questionaire (SAQ), TCM symptom score] of the two groups were observed before and after treatment. The incidence of postoperative complications after nursing intervention was recorded. RESULTS: After nursing intervention, each score and total scores of the self-administration scale of the combined group were higher than those of the fine group (P < 0.05). After the nursing intervention, each score and the total scores of the self-efficacy scale of the combined group were higher than the fine group (P < 0.05) After the nursing intervention, the SAQ score of the combined group was significantly higher than that of the fine group (P < 0.05). After the nursing intervention, TCM symptom score of the combined group was significantly lower than that of the fine group (P < 0.05). After nursing intervention, the postoperative complication rate of the combined group was 79.03%, which was lower than that of the fine group (59.68%)(P < 0.05). CONCLUSION: Patients with coronary intervention, who use traditional Chinese medicine combined with refined nursing, can improve their quality of life, clinical symptoms and postoperative complications by improving their self-management and efficacy, which is conducive to the recovery of patients' follow-up.展开更多

Good gallbladder contraction function was confirmed by type B ultrasonography. Dilation of the CBD and cystic duct was detected. Percutaneous transhepatic balloon dilation of the papilla was performed, ursodeoxycholic acid was administered, and all patients had a high-fat diet. All subjects underwent repeated cholangiography, and percutaneous transhepatic removal was carried out in patients with secondary CBD stones originating from the gallbladder. RESULTS All patients underwent percutaneous transhepatic balloon dilation with a primary success rate of 100%. The combined therapy was successful in 86.7% of patients with concomitant CBD stones and gallstones. No remaining stones were detected in the gallbladder. Transient adverse events include abdominal pain(n = 1), abdominal distension(n = 1), and fever(n = 1). Complications were treated successfully via nonsurgical management without long-term complications. No procedure-related mortality occurred. CONCLUSION For patients with concomitant CBD stones and gallstones, after percutaneous transhepatic removal of primary CBD stones, oral ursodeoxycholic acid and a high-fat diet followed by percutaneous transhepatic removal of secondary CBD stones appear to be a feasible and effective option for management of gallstones.展开更多

METHODS We specifically report a retrospective study presenting the results of percutaneous intraductal RF in patients with biliary stent occlusion. A total of 43 cases involving biliary stent obstruction were treated by placing an EndoHPB catheter and percutaneous intraductal RF was performed to clean stents. The stent patency was evaluated by cholangiography and follow-up by contrast enhanced computed tomography or ultrasound after the removal of the drainage catheter. RESULTS Following the procedures, of the 43 patients, 40 survived and 3 died with a median survival of 80.5 (range: 30-243) d. One patient was lost to followup. One patient had the stent patent at the time of last follow-up. Two patients with stent blockage at 35 d and 44 d after procedure underwent percutaneous transhepatic drain insertion only. The levels of bilirubin before and after the procedure were 128 +/- 65 mu mol/L and 63 +/- 29 mu mol/L, respectively. There were no related complications (haemorrhage, bile duct perforation, bile leak or pancreatitis) and all patients' stent patency was confirmed by cholangiography after the procedure, with a median patency time of 107 (range: 12-180) d. CONCLUSION This preliminary clinical study demonstrated that percutaneous intraductal RF is safe and effective for the treatment of biliary stent obstruction, increasing the duration of stent patency, although randomized controlled trials are needed to confirm the effectiveness of this approach.展开更多

The purpose of this study was to investigate whether the genetic polymorphisms of UDP-glucuronosyltransferase（UGT1A7）, an important phase II biotransformation enzyme, and X-ray repair cross-complementing group 1（XRCC1）, a pivotal DNA-repair gene, were related to the risk of HCC in Northeast China. Methods： One hundred and thirty six HCC patients and one hundred and thirty six frequency-matched controls were included in this hospital-based case-control study. Genotypes of UGT1A7 and XRCC1 were determined using allele-specific polymerase chain reaction （AS-PCR） and PCR-restriction fragment length polymorphism （RFLP）, and for which the odds ratio （OR） with 95% confidence interval （95% CI） were calculated. Results： The proportion of UGT1A7 low enzymatic allele （＊2 or ＊3） was higher in HCC patients than those in controls. The UGT1A7＊1/＊2 and ＊3/＊3 genotypes were associated with higher HCC risk （OR=2.09, 95%CI： 1.10-3.97; OR=5.67, 95%CI： 1.76-18.30, respectively）. The XRCC1 codon 399 Arg/Gln genotype could also elevate HCC risk （OR=2.16, 95% CI 1.29-3.61）. In addition to polymorphisms of UGT1A7 and XRCC1, multivariate logistic regression analysis demonstrated that other significant independent factors associated with HCC were HBV infection （OR=68.07, 95%CI： 28.03-165.26）, HCV infection （OR=30.97, 95%CI： 8.06-118.94） and family history of HCC （OR=10.62, 95%CI： 2.22-50.77）. Conclusion： The study shows that the polymorphisms of UGT1A7 and XRCC1 are associated with HCC risk. Determination of the polymorphisms of UGT1A7 and XRCC1 may provide an important clue to preventive measure against HCC.展开更多

One week ago, he was admitted with bilateral lower limb swelling and pain. Digital subtraction angiography showed a filling defect above the original filter. A retrievable Tulip filter was placed and catheter-directed thrombolysis was performed. Six days later, the patient experienced sudden, persistent upper right abdominal pain, and a computed tomography scan revealed the formation of retroperitoneal hematoma. Symptomatic treatments were administered, and the hematoma gradually resolved during follow-up.展开更多

Follow-up of embolized intracrania...Purpose: The endovascular treatment of intracranial aneurysms was proven safe and effective compared to the alternative method of surgical clipping, despite the high recurrence rate. Follow-up of embolized intracranial aneurysms is mandatory for the early detection of recurrence and improved outcomes. DSA is used as the reference standard for this assessment. To determine the effectiveness of MRA in follow-up evaluations of intracranial aneurysms after embolization by comparing DSA, CE-MRA, and TOF-MRA. Materials and Methods: Sixty-eight consecutive patients undergoing DSA, TOF-MRA, and CE-MRA during an interval of <1 week were enrolled in this 6-month study. Images were evaluated for occlusion status, patency of the parent vessels, and artifacts. The modified Raymond-Roy occlusion classification and Aneurysm Embolization Grades were used to assess the occlusion status and initial DSA images for detection of recurrence in two filtered study phases with optimized selection criteria. Seventeen observers(phase I: 9, phase II: 8) independently interpreted the double-blinded images. Agreement was expressed with a Fleiss kappa value; p < 0.05 was considered significant. Results: This study included 68 patients with 77 aneurysms; 38(49.35%) were treated with coil alone and 39(50.65%) with stent-assisted coiling. In both phases, DSA was superior to TOF-MRA and CE-MRA using MRRC(Phase I: k = 0.567, p ≤ 0.001; k = 0.287, p ≤ 0.001; k = 0.117, p ≤ 0.001, respectively; Phase II: k = 0.503, p ≤ 0.001; k = 0.303, p ≤ 0.001; k = 0.115, p = 0.038, respectively). TOF-MRA was as effective as DSA(TOF: k = 0.335, p ≤ 0.001; DSA: k = 0.323, p ≤ 0.001) for recurrence detection. Conclusion: We suggest TOF-MRA as a first-line follow-up tool to detect aneurysm recurrence, and DSA to quantify the filling space to make a definite decision on re-embolization.展开更多

文摘BACKGROUND Uridine diphosphate glucuronosyltransferase 1A1(UGT1A1)plays a crucial role in metabolizing and detoxifying endogenous and exogenous substances.However,its contribution to the progression of liver damage remains unclear.AIM To determine the role and mechanism of UGT1A1 in liver damage progression.METHODS We investigated the relationship between UGT1A1 expression and liver injury through clinical research.Additionally,the impact and mechanism of UGT1A1 on the progression of liver injury was analyzed through a mouse model study.RESULTS Patients with UGT1A1 gene mutations showed varying degrees of liver damage,while patients with acute-onchronic liver failure(ACLF)exhibited relatively reduced levels of UGT1A1 protein in the liver as compared to patients with chronic hepatitis.This suggests that low UGT1A1 levels may be associated with the progression of liver damage.In mouse models of liver injury induced by carbon tetrachloride(CCl_(4))and concanavalin A(ConA),the hepatic levels of UGT1A1 protein were found to be increased.In mice with lipopolysaccharide or liver steatosis-mediated liver-injury progression,the hepatic protein levels of UGT1A1 were decreased,which is consistent with the observations in patients with ACLF.UGT1A1 knockout exacerbated CCl_(4)-and ConA-induced liver injury,hepatocyte apoptosis and necroptosis in mice,intensified hepatocyte endoplasmic reticulum(ER)stress and oxidative stress,and disrupted lipid metabolism.CONCLUSION UGT1A1 is upregulated as a compensatory response during liver injury,and interference with this upregulation process may worsen liver injury.UGT1A1 reduces ER stress,oxidative stress,and lipid metabolism disorder,thereby mitigating hepatocyte apoptosis and necroptosis.

文摘BACKGROUND Indentifying predictive factors for postoperative recurrence of hepatocellular carcinoma(HCC)has great significance for patient prognosis.AIM To explore the value of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid(Gd-EOB-DTPA)enhanced magnetic resonance imaging(MRI)combined with clinical features in predicting early recurrence of HCC after resection.METHODS A total of 161 patients with pathologically confirmed HCC were enrolled.The patients were divided into early recurrence and non-early recurrence group based on the follow-up results.The clinical,laboratory,pathological results and Gd-EOB-DTPA enhanced MRI imaging features were analyzed.RESULTS Of 161 patients,73 had early recurrence and 88 were had non-early recurrence.Univariate analysis showed that patient age,gender,serum alpha-fetoprotein level,the Barcelona Clinic Liver Cancer stage,China liver cancer(CNLC)stage,microvascular invasion(MVI),pathological satellite focus,tumor size,tumor number,tumor boundary,tumor capsule,intratumoral necrosis,portal vein tumor thrombus,large vessel invasion,nonperipheral washout,peritumoral enhancement,hepatobiliary phase(HBP)/tumor signal intensity(SI)/peritumoral SI,HBP peritumoral low signal and peritumoral delay enhancement were significantly associated with early recurrence of HCC after operation.Multivariate logistic regression analysis showed that patient age,MVI,CNLC stage,tumor boundary and large vessel invasion were independent predictive factors.External data validation indicated that the area under the curve of the combined predictors was 0.861,suggesting that multivariate logistic regression was a reasonable predictive model for early recurrence of HCC.CONCLUSION Gd-EOB-DTPA enhanced MRI combined with clinical features would help predicting the early recurrence of HCC after operation.
文摘BACKGROUND Intracranial arterial narrowing is a significant factor leading to brief episodes of reduced blood flow to the brain,known as transient ischemic attacks,or fullblown strokes.While atherosclerosis is commonly associated with intracranial arterial narrowing,it is frequently of a non-atherosclerotic nature in younger patients.CASE SUMMARY Here,we present the case of a young stroke patient with narrowing of the middle cerebral artery(MCA),characterized as non-atherosclerotic lesions,who experienced an ischemic stroke despite receiving standard drug therapy.The patient underwent digital subtraction angiography(DSA)to assess the entire network of blood vessels in the brain,revealing significant narrowing(approximately 80%)in the M1 segment of the right MCA.Subsequently,the patient underwent Drug-Coated Balloon Angioplasty to treat the stenosis in the right MCA's M1 segment.Follow-up DSA confirmed the resolution of stenosis in this segment.Although the remaining branches showed satisfactory blood flow,the vessel wall exhibited irregularities.A review of DSA conducted six months later showed no evident stenosis in the right MCA,with a smooth vessel wall.CONCLUSION The use of drug-coated balloon angioplasty demonstrated favorable outcomes in repairing and reshaping the blood vessel wall in young patients.Therefore,it may be considered a promising treatment option for similar cases.
文摘Subtle changes have occurred in China, and interventional radiology has gradually become an independent specialty, separated from diagnostic radiology. This has been called "Interventionalogy", "interventional medicine(IM)", or simply Intervention by our team,and "Interventional Radiology" is used no more. It has even been given the name "Third clinical Medicine" by us. Chinese intervention has established an independent association for interventional doctors, as well as independent interventional societies in many provinces. The national interventional society will likely be set up at some point in time. Chinese interve ntion has set up their own clinical wards, with much attention paid to a clinical, professional, and normalized direction for development, and established special nursing units. According to us, turf battle is meaningless. "The Third clinical Medicine" belongs to all human beings. It could also be predicted that interventional history will follow the same evolutionary rule as other disciplines, i.e., "long divided, must unite; long united, must divide".
文摘OBJECTIVE: To study the effects on self-efficacy and quality of life in patients undergoing coronary intervention, by traditional Chinese medicine nursing combined with refined nursing. METHODS: A total of 124 patients, who needed to undergo coronary intervention in our hospital, were randomly divided into the fine group and the combined group, with 62 patients in each group. The two groups of patients were enrolled in the PCI routine nursing procedure, in which the fine group was given refined nursing, and the joint group, based on that, added the traditional Chinese medicine nursing. The self-management (self-management scale of coronary heart disease), self-efficacy (self-efficacy scale of coronary heart disease), quality of life score (Seattle angina questionaire (SAQ), TCM symptom score] of the two groups were observed before and after treatment. The incidence of postoperative complications after nursing intervention was recorded. RESULTS: After nursing intervention, each score and total scores of the self-administration scale of the combined group were higher than those of the fine group (P < 0.05). After the nursing intervention, each score and the total scores of the self-efficacy scale of the combined group were higher than the fine group (P < 0.05) After the nursing intervention, the SAQ score of the combined group was significantly higher than that of the fine group (P < 0.05). After the nursing intervention, TCM symptom score of the combined group was significantly lower than that of the fine group (P < 0.05). After nursing intervention, the postoperative complication rate of the combined group was 79.03%, which was lower than that of the fine group (59.68%)(P < 0.05). CONCLUSION: Patients with coronary intervention, who use traditional Chinese medicine combined with refined nursing, can improve their quality of life, clinical symptoms and postoperative complications by improving their self-management and efficacy, which is conducive to the recovery of patients' follow-up.
文摘Malignant tumors are major causes of morbidity and mortality in China.Despite advances in surgical,radiological,chemotherapeutic,molecular targeting,and immunotherapeutic treatments,patients with malignant tumors still have poor prognoses.Low-dose-rate brachytherapy,specifically 125I seed implantation,is beneficial because of its high local delivery dose and minimal damage to surrounding tissues.Consequently,it has gained increasing acceptance as a treatment modality for various malignant tumors.In this study,we explored the fundamental principles,clinical applications,and new technologies associated with 125I radioactive seed implantation.

文摘Objective:To investigate the effect of arterial interventional chemotherapy before radical operation for gastric cancer on serum tumor markers and cell growth in the lesion.Methods:90 patients with primary gastric cancer who underwent radical operation for gastric cancer in our hospital were chosen as the research subjects and divided into the control group (n=48) (did not receive preoperative arterial interventional chemotherapy) and the arterial interventional chemotherapy group (n=42) (received preoperative arterial interventional chemotherapy). The differences in tumor markers in serum as well as proliferation and apoptosis gene expression in gastric cancer tissues were compared.Results: Before surgery started, serum CA199, CA153, CA724 and AFP levels of arterial interventional chemotherapy group were significantly lower than those immediately after admission whereas serum CA199, CA153, CA724 and AFP levels of control group were not significantly different from those immediately after admission. After surgery, proliferation genes CUL4A and NTSR1 mRNA expression in gastric cancer tissues of arterial interventional chemotherapy group were lower than those of control group whereas DADS and FAM96B mRNA expression were higher than those of control group;apoptosis genes Livin and Bcl-2 mRNA expression were lower than those of control group whereas p53, p21 and Bax mRNA expression were higher than those of control group.Conclusion:Preoperative arterial interventional chemotherapy combined with radical operation for gastric cancer can more effectively inhibit the malignant degree of tumor and delay the growth of cancer cells.
文摘Budd-Chiari syndrome(BCS)is a rare condition characterized by hepatic venous outflow obstruction.Balloon angioplasty,with or without stenting,is the recommended first-line treatment modality in Asian countries.As a supplement to balloon angioplasty,expandable metallic Z-stent deployment can effectively improve long-term inferior vena cava(IVC)patency.Although stent placement is a standard and frequently performed treatment,very few IVC stent-related complications,such as stent fractures,have been reported.Here we present a case series and a comprehensive review of IVC stent fractures in patients with BCS.The most common characteristic of IVC stent fractures is a protrusion of the proximal segment of the IVC stent into the right atrium and its systolic and diastolic movements along with heart rhythms.Accurate stent deployment,large-diameter balloon dilation,patient breath-holding training,preferential selection of a triple stent,and the use of an internal jugular vein approach to stent deployment may ensure precise stent localization and avoid postoperative complications.

文摘AIM To evaluate the effectiveness and safety of combined ursodeoxycholic acid and percutaneous transhepatic balloon dilation for management of gallstones after expulsion of common bile duct(CBD) stones.METHODS From April 2014 to May 2016, 15 consecutive patients(6 men and 9 women) aged 45-86(mean, 69.07 ± 9.91) years suffering from CBD stones associated with gallstones were evaluated. Good gallbladder contraction function was confirmed by type B ultrasonography. Dilation of the CBD and cystic duct was detected. Percutaneous transhepatic balloon dilation of the papilla was performed, ursodeoxycholic acid was administered, and all patients had a high-fat diet. All subjects underwent repeated cholangiography, and percutaneous transhepatic removal was carried out in patients with secondary CBD stones originating from the gallbladder. RESULTS All patients underwent percutaneous transhepatic balloon dilation with a primary success rate of 100%. The combined therapy was successful in 86.7% of patients with concomitant CBD stones and gallstones. No remaining stones were detected in the gallbladder. Transient adverse events include abdominal pain(n = 1), abdominal distension(n = 1), and fever(n = 1). Complications were treated successfully via nonsurgical management without long-term complications. No procedure-related mortality occurred. CONCLUSION For patients with concomitant CBD stones and gallstones, after percutaneous transhepatic removal of primary CBD stones, oral ursodeoxycholic acid and a high-fat diet followed by percutaneous transhepatic removal of secondary CBD stones appear to be a feasible and effective option for management of gallstones.

文摘AIM To assess the feasibility and effectiveness of a novel application of percutaneous intraductal radiofrequency (RF) for the treatment of biliary stent obstruction. METHODS We specifically report a retrospective study presenting the results of percutaneous intraductal RF in patients with biliary stent occlusion. A total of 43 cases involving biliary stent obstruction were treated by placing an EndoHPB catheter and percutaneous intraductal RF was performed to clean stents. The stent patency was evaluated by cholangiography and follow-up by contrast enhanced computed tomography or ultrasound after the removal of the drainage catheter. RESULTS Following the procedures, of the 43 patients, 40 survived and 3 died with a median survival of 80.5 (range: 30-243) d. One patient was lost to followup. One patient had the stent patent at the time of last follow-up. Two patients with stent blockage at 35 d and 44 d after procedure underwent percutaneous transhepatic drain insertion only. The levels of bilirubin before and after the procedure were 128 +/- 65 mu mol/L and 63 +/- 29 mu mol/L, respectively. There were no related complications (haemorrhage, bile duct perforation, bile leak or pancreatitis) and all patients' stent patency was confirmed by cholangiography after the procedure, with a median patency time of 107 (range: 12-180) d. CONCLUSION This preliminary clinical study demonstrated that percutaneous intraductal RF is safe and effective for the treatment of biliary stent obstruction, increasing the duration of stent patency, although randomized controlled trials are needed to confirm the effectiveness of this approach.
文摘Objective:To investigate the clinical utility of ultrasound-guided balloon occlusion in cesarean section in patients with sinister placenta previa.Methods:The Interventional and Ultrasound Departments of the authors’center assisted obstetrics to complete cesarean section in cases of sinister placenta previa.A total of 130 patients with implanted sinister placenta previa were diagnosed using obstetrical ultrasound and magnetic resonance imaging(MRI).Before cesarean section,the balloon was positioned in the bilateral radial or abdominal aorta.Immediately after delivery of the fetus,the balloon was temporarily filled to transiently seal the target vessel.According to the obstetrician’s assessment of hemostasis,the balloon was withdrawn at the appropriate time.Among the 130 patients,there was one case of abdominal aortic occlusion,with 129 cases blocked by the bilateral common iliac artery.Results:All 130 cases were successfully blocked,with an average blocking time of<15 min,while intraoperative blood loss was 800–1500 ml.Conclusion:Ultrasound-guided balloon blocking treatment before cesarean section can mitigate the dangers of placenta previa and significantly reduce blood loss with no exposure to X-ray radiation.Thus,the technique merits serious consideration.

文摘Objective： Hepatocellular carcinoma （HCC） is a complex disease which associates with both environmental and genetic factors. The purpose of this study was to investigate whether the genetic polymorphisms of UDP-glucuronosyltransferase（UGT1A7）, an important phase II biotransformation enzyme, and X-ray repair cross-complementing group 1（XRCC1）, a pivotal DNA-repair gene, were related to the risk of HCC in Northeast China. Methods： One hundred and thirty six HCC patients and one hundred and thirty six frequency-matched controls were included in this hospital-based case-control study. Genotypes of UGT1A7 and XRCC1 were determined using allele-specific polymerase chain reaction （AS-PCR） and PCR-restriction fragment length polymorphism （RFLP）, and for which the odds ratio （OR） with 95% confidence interval （95% CI） were calculated. Results： The proportion of UGT1A7 low enzymatic allele （＊2 or ＊3） was higher in HCC patients than those in controls. The UGT1A7＊1/＊2 and ＊3/＊3 genotypes were associated with higher HCC risk （OR=2.09, 95%CI： 1.10-3.97; OR=5.67, 95%CI： 1.76-18.30, respectively）. The XRCC1 codon 399 Arg/Gln genotype could also elevate HCC risk （OR=2.16, 95% CI 1.29-3.61）. In addition to polymorphisms of UGT1A7 and XRCC1, multivariate logistic regression analysis demonstrated that other significant independent factors associated with HCC were HBV infection （OR=68.07, 95%CI： 28.03-165.26）, HCV infection （OR=30.97, 95%CI： 8.06-118.94） and family history of HCC （OR=10.62, 95%CI： 2.22-50.77）. Conclusion： The study shows that the polymorphisms of UGT1A7 and XRCC1 are associated with HCC risk. Determination of the polymorphisms of UGT1A7 and XRCC1 may provide an important clue to preventive measure against HCC.

文摘Background:A ruptured hepatocellular carcinoma(HCC)is often fatal.In addition to surgery and transarterial embo?lization,radiofrequency ablation(RFA)might be another option for treating a ruptured HCC.Unfortunately,conven?tional RFA has a limited ablation zone;as such,it is rarely used to treat ruptured tumors.Case presentation:This case was a 60?year?old man who had a large,ruptured HCC in which hydrochloric acid(HCl)?enhanced RFA successfully controlled the bleeding and made the tumor completely necrotic.Conclusion:Considering the effectiveness of HCl?enhanced RFA in achieving hemostasis and tumor ablation,it might be a new option for treating large,ruptured HCCs.
文摘A 55-year-old man developed deep venous thrombosis and inferior vena cava(IVC) thrombosis 7 years earlier and was treated by placement of a permanent IVC filter. One week ago, he was admitted with bilateral lower limb swelling and pain. Digital subtraction angiography showed a filling defect above the original filter. A retrievable Tulip filter was placed and catheter-directed thrombolysis was performed. Six days later, the patient experienced sudden, persistent upper right abdominal pain, and a computed tomography scan revealed the formation of retroperitoneal hematoma. Symptomatic treatments were administered, and the hematoma gradually resolved during follow-up.
文摘Purpose: The endovascular treatment of intracranial aneurysms was proven safe and effective compared to the alternative method of surgical clipping, despite the high recurrence rate. Follow-up of embolized intracranial aneurysms is mandatory for the early detection of recurrence and improved outcomes. DSA is used as the reference standard for this assessment. To determine the effectiveness of MRA in follow-up evaluations of intracranial aneurysms after embolization by comparing DSA, CE-MRA, and TOF-MRA. Materials and Methods: Sixty-eight consecutive patients undergoing DSA, TOF-MRA, and CE-MRA during an interval of <1 week were enrolled in this 6-month study. Images were evaluated for occlusion status, patency of the parent vessels, and artifacts. The modified Raymond-Roy occlusion classification and Aneurysm Embolization Grades were used to assess the occlusion status and initial DSA images for detection of recurrence in two filtered study phases with optimized selection criteria. Seventeen observers(phase I: 9, phase II: 8) independently interpreted the double-blinded images. Agreement was expressed with a Fleiss kappa value; p < 0.05 was considered significant. Results: This study included 68 patients with 77 aneurysms; 38(49.35%) were treated with coil alone and 39(50.65%) with stent-assisted coiling. In both phases, DSA was superior to TOF-MRA and CE-MRA using MRRC(Phase I: k = 0.567, p ≤ 0.001; k = 0.287, p ≤ 0.001; k = 0.117, p ≤ 0.001, respectively; Phase II: k = 0.503, p ≤ 0.001; k = 0.303, p ≤ 0.001; k = 0.115, p = 0.038, respectively). TOF-MRA was as effective as DSA(TOF: k = 0.335, p ≤ 0.001; DSA: k = 0.323, p ≤ 0.001) for recurrence detection. Conclusion: We suggest TOF-MRA as a first-line follow-up tool to detect aneurysm recurrence, and DSA to quantify the filling space to make a definite decision on re-embolization.
文摘Background context:Metastatic spinal cord compression(MSCC)seriously affects the survival rate.Objective:The therapeutic effects of two treatment strategies for MSCC:percutaneous vertebroplasty(PVP)combined with radiofrequency ablation(RFA)and PVP combined with^(125)I particle implantation,were compared.Study design:Retrospective study.Patient sample:40 patients with MSCC were divided into two groups:19 cases in the RFA group and 21 cases in the^(125)I group.Method:All patients were accessed to determine the differences in pain,which was evaluated using the visual analog scale(VAS)at 1 week,1 month,and 3 months after the operation,and spinal stenosis rates(SSRs),which were measured at 1 and 3 months after the operation,between the two groups.Results:The VAS scores and SSRs at baseline were comparable between the RFA group and the^(125)I group(7.19±2.07 vs 7.42±1.95,37.7%±11.2%vs 41.1%±11.4%).The VAS scores and SSRs at 1 month and 3 months after the operation were significantly reduced in both groups,compared with those at baseline.The VAS scores and SSRs in the^(125)I group were lower than those in the RFA group at 3 months after the operation(1.09±0.97 vs 1.75±1.06 p=0.048 and 12.3%±6.4%vs 18.1%±10.1%p=0.034),while the VAS scores at1 week after the operation in the RFA group were lower than those in the^(125)I group(4.39±1.34 vs 5.05±1.82 p=0.049).Conclusion:PVP combined with RFA has a slight advantage in relieving pain in the short term,while PVP combined with^(125)I particle implantation may have a better effect in the relieving pain and decreasing the SSRs at 3 months after the operation.
文摘Objective:Transarterial and transvenous embolization methods are considered effective and safe approaches for the treatment of cavernous sinus dural arteriovenous fistula(CSDAVF).Here.,we report the angioarchitectural features and clinical outcomes of CSDAVF in patients treated with either the inferior arterial approach(IAA) or the inferior petrosal sinus approach(IPSA).Methods:The clinical data of 32 patients with CSDAVF treated at our institution from May 2008 to May 2014 were retrospectively analyzed.All patients underwent routine diagnostic digital subtraction angiography(DSA) before surgery.Embolization was performed using the IPSA through the internal jugular vein or IAA,based on angioarchitectural features.Results:Of the 32 patients with CSDAVF,24 underwent embolization treatment through the internal jugular veinIPSA and 8 patients underwent treatment through IAA.Nineteen patients in the IPSA group experienced mild headache,which improved after specific treatment.The immediate postembolization angiographic results revealed complete occlusion in 26 cases(18 IPSA and 8 IAA) and almost complete occlusion in 6 cases(IPSA).Complications that occurred during the procedure included abducens nerve palsy(n=1,IPSA) and prosopoplegia(n=1,IAA).One patient developed tinnitus,which was diagnosed as anterior cranial fossa new-onset dural arteriovenous fistula on DSA,whereas the symptoms of other patients all improved with no recurrence.Conclusions:On the basis of the angioarchitectural features of CSDAVF,IAA can be considered the primary treatment when the blood-supplying artery and fistula are relatively singular,and when the microcatheter can easily reach the fistula through the artery.The venous approach should be selected as the primary approach when the fistula is indistinguishable and blood is supplied by multiple arteries through small plexiform vessels.Choosing the optimal surgical approach may increase the success rate of intravascular CSDAVF surgery and may help avoid complications.
文摘BACKGROUND Implanted intravenous infusion port(IVAP)is indicated for patients undergoing chemotherapy,total parenteral nutrition and long-term antibiotic treatment.Among their complications,the rupture and migration of the catheter of an IVAP via internal jugular vein represents a very rare but potentially severe condition.CASE SUMMARY A 43-year-old woman was identified with a spontaneous fracture and migration of catheter of an IVAP via right internal jugular vein after adjuvant chemotherapy for left breast cancer.A computed tomography showed the fractured catheter of the IVAP in the pulmonary artery.Therefore,we conducted an emergency procedure to remove the catheter fragment by a pigtail catheter combined with a gooseneck trap.CONCLUSION When the fractured catheter of an IVAP was detected,the special shape of the pigtail catheter in combination with the gooseneck trap successfully facilitated the removal of the dislodged catheter.
