For patients with hemispatial neglect (HSN) during acute stroke, whether HSN disappearance is related to those trainings or not should be further studied. OBJECTIVE: To analyze the correlation between HSN disappearance and related intervention of patients during acute stroke. DESIGN: Case analysis. SETTING: Department of Neurology, First Affiliated Hospital of Guangxi Medical University. PARTICIPANTS: A total of 21 patients with stroke were selected from the Department of Neurology, the First Affiliated Hospital of Guangxi Medical University from May 2005 to March 2006. Diagnosis criteria: ① Stroke was diagnosed by CT and MRI; ② Diagnosis was coincidence with HSN evaluation criteria; ③ All cases were consent. Exclusion criteria: Patients who had poly-focus, conscious disturbance, severe amentia and hard communication combined with aphasia were excluded. A total of 12 males and 9 females were included, and the mean age was (68±10) years. Among them, 14 patients had cerebral infarction and 7 had cerebral hemorrhage. METHODS: Disappearance and existence of HSN were analyzed with HSN evaluation criteria: body agnosia, left and right agnosia, maintenance of supine position, place of things, sitting up straight, center of line measured by eyes, and cutting 30 lines with paring method. Items mentioned below belonged to HSN disappearance: ① without body agnosia; ② without left and right agnosia; ③ be able to maintain supine position; ④ knowing place of things; ⑤ sitting up straight by one’s own; ⑥ be able to measure the center of line by eyes; ⑦ be able to cut 30 lines with paring method. However, only one item belonged to HSN remnant; but only one item belonged to HSN remnant. Numbers of patients who were of body agnosia, left and right agnosia and difficult maintenance of supine position were observed during acute period (within 1 week) and recovery period (at 2 weeks after onset). Related factors with HSN disappearance contained time of physiotherapy, duration of sitting training (sitting in bed and near bedside: heels fallen to ground, feet loaded heavies, center of gravity located at middle line, head raised towards frontage) and hospitalized time. However, control group was not set up.Measurement data were expressed as Mean±SD and compared with t test; enumeration data were compared with Chi-square test and Mann-Whitney U test. P < 0.05 was regarded as significant difference. MAIN OUTCOME MEASURES: ① HSN disappearance; ② Numbers of body agnosia, left and right agnosia and difficult maintenance of supine position; ③ Correlation among therapeutic time, sitting-training time and hospitalized time. RESULTS: All 21 patients were involved in the final analysis. ① HSN disappearance: Among 21 cases, 2 patients had right HSN disappearance, 19 left HSN disappearance, 8 (38%, 8/21) HSN disappearance, and 13 (62%, 13/21) HSN remnant. Among 8 patients of HSN disappearance, symptoms of 4 cases lasted for 7 days and that of another 4 lasted for 8-12 days. ② Evaluation of HSN disappearance at various phases: Within 1 week, 19% (4/21) HSN patients had body agnosia, left and right agnosia; during recovery period, body agnosia of 20 cases was disappeared and that of 1 case was still survived. Within 1 week, cases with difficult maintenance of supine position were 67% (13/21), but 43% (17/21) during recovery period. ③ Analysis of effective factors on HSN disappearance and related intervention: At acute phase, HSN disappearance through sitting training lasted for (2.5±1.3) days, and remaining HSN symptoms were relieved for (5.0±3.7) days. There was significant difference between them (χ2 = 3.96, P = 0.039). The hospitalized time of patients with HSN disappearance and HSN remnant was (17.6±10.4), (16.2±4.9) days, but there was no significant difference between them (χ2 = 1.41, P = 0.679). Physiotherapy time of patients with HSN disappearance and HSN remnant was (11.1±7.5), (11.4±4.1) days, but there was no significant difference between them (χ2 = 1.05?熏 P = 0.894?雪. CONCLUSION: Early sitting training may play a possible role in HSN symptom disappearance of patients with stroke.展开更多

Intravenous thrombolysis with tissue plasminogen activator (tPA) is one of the effective therapies to achieve revascularization, but it faces strict indications with a narrow therapeutic time window, and significantly increases the incidence of hemorrhagic transformation, HT, after reperfusion of the infarcted foci, which greatly reduces the incidence of patients with ischemic stroke. which significantly increases the incidence of hemorrhagic transformation (HT) after reperfusion of the infarcted focus, greatly reducing patient utilization and clinical benefit. Since the mechanism of HT has not been fully elucidated, and the related molecular mechanisms are complex and interactive, there is no specific and effective therapy to avoid the occurrence of HT. In this article, we focus on the research progress on the mechanism of HT after tPA intravenous thrombolysis in ischemic stroke patients from the aspects of vascular integrity disruption, oxidative stress, and neuroinflammatory response and the corresponding therapeutic strategies, in order to improve the safety and prognosis of tPA intravenous thrombolysis in the clinic.展开更多

Methods: Patients who visited the emergency service of Yozgat City Hospital between 1 April 2017 and 1 July 2017 and those hospitalized with a diagnosis of ischemic stroke, were included in this retrospective study. The clinical information of the patients was collected via hospital files and telephone interviews. In addition, the potential association between arrival time and the clinical parameters was investigated. Results: A total of 87 patients were included. The median arrival time to emergency service was 5 (IQR=9) h. Forty-four percent of patients arrived within the first 4.5 h from symptom onset. However, intravenous thrombolytic treatment was performed in only 7% of the patients. The median time from arrival to neuroimaging performing was 20.0 (IQR=34) min. Fifty-one percent of patients were screened within the first 20 min from arrival to emergency service. There was no association between arrival time and transfer method of the patients. Conclusions: The main problem regarding acute stroke care in our region may be inefficient use of emergency ambulance. This study provides basis for measures to shorten the arrival time.展开更多

However, post-stroke hyperglycemia is also present in a number of non-diabetic patients after acute ischemic stroke, presumably as a stress response. The aim of this review is to summarize the main effects of hyperglycemia when associated to ischemic injury in acute stroke patients, highlighting the clinical and neurological outcomes in these conditions and after the administration of the currently approved pharmacological treatment, i.e. insulin. The disappointing results of the clinical trials on insulin(including the hypoglycemic events) demand a change of strategy based on more focused therapies. Starting from the comprehensive evaluation of the physiopathological alterations occurring in the ischemic brain during hyperglycemic conditions, the effects of various classes of glucose-lowering drugs are reviewed, such as glucose-like peptide-1 receptor agonists, DPP-4 inhibitors and sodium glucose cotransporter 2 inhibitors, in the perspective of overcoming the up-to-date limitations and of evaluating the effectiveness of new potential therapeutic strategies.展开更多

文摘BACKGROUND Aspirin is a widely used antiplatelet agent that reduces the risk of recurrent ischemic stroke and other vascular events.However,the optimal timing and dose of aspirin initiation after an acute stroke remain controversial.AIM To evaluate the efficacy and safety of aspirin antiplatelet therapy within 48 h of symptom onset in patients with acute stroke.METHODS We conducted a randomized,open-label,controlled trial in 60 patients with acute ischemic or hemorrhagic stroke who were admitted to our hospital within 24 h of symptom onset.Patients were randomly assigned to receive either aspirin 300 mg daily or no aspirin within 48 h of stroke onset.The primary outcome was the occurrence of recurrent stroke,myocardial infarction,or vascular death within 90 d.The secondary outcomes were functional outcomes at 90 d measured using the modified Rankin Scale(mRS),incidence of bleeding complications,and mortality rate.RESULTS The mean age of the patients was 67.8 years and 55%of them were male.The median time from stroke onset to randomization was 12 h.The baseline characteristics were well balanced between the two groups.The primary outcome occurred in 6.7%of patients in the aspirin group and 16.7%of patients in the no aspirin group(relative risk=0.40,95%confidence interval:0.12-1.31,P=0.13).The mRS score at 90 d was significantly lower in the aspirin group than in the no aspirin group(median,2 vs 3,respectively;P=0.04).The incidence of bleeding complications was similar between the groups(6.7%vs 6.7%,P=1.00).The mortality rates were also comparable between the two groups(10%vs 13.3%,P=0.69).CONCLUSION Aspirin use is associated with favorable functional outcomes but does not significantly reduce the risk of recurrent vascular events.Its acceptable safety profile is comparable to that of no aspirin.Further studies with larger sample sizes and longer follow-up periods are needed to confirm these findings.
文摘BACKGROUND: Some researches are proved that early sitting balance and body motor control performed on patients with stroke and hemiplegia is related to functional prognosis. For patients with hemispatial neglect (HSN) during acute stroke, whether HSN disappearance is related to those trainings or not should be further studied. OBJECTIVE: To analyze the correlation between HSN disappearance and related intervention of patients during acute stroke. DESIGN: Case analysis. SETTING: Department of Neurology, First Affiliated Hospital of Guangxi Medical University. PARTICIPANTS: A total of 21 patients with stroke were selected from the Department of Neurology, the First Affiliated Hospital of Guangxi Medical University from May 2005 to March 2006. Diagnosis criteria: ① Stroke was diagnosed by CT and MRI; ② Diagnosis was coincidence with HSN evaluation criteria; ③ All cases were consent. Exclusion criteria: Patients who had poly-focus, conscious disturbance, severe amentia and hard communication combined with aphasia were excluded. A total of 12 males and 9 females were included, and the mean age was (68±10) years. Among them, 14 patients had cerebral infarction and 7 had cerebral hemorrhage. METHODS: Disappearance and existence of HSN were analyzed with HSN evaluation criteria: body agnosia, left and right agnosia, maintenance of supine position, place of things, sitting up straight, center of line measured by eyes, and cutting 30 lines with paring method. Items mentioned below belonged to HSN disappearance: ① without body agnosia; ② without left and right agnosia; ③ be able to maintain supine position; ④ knowing place of things; ⑤ sitting up straight by one’s own; ⑥ be able to measure the center of line by eyes; ⑦ be able to cut 30 lines with paring method. However, only one item belonged to HSN remnant; but only one item belonged to HSN remnant. Numbers of patients who were of body agnosia, left and right agnosia and difficult maintenance of supine position were observed during acute period (within 1 week) and recovery period (at 2 weeks after onset). Related factors with HSN disappearance contained time of physiotherapy, duration of sitting training (sitting in bed and near bedside: heels fallen to ground, feet loaded heavies, center of gravity located at middle line, head raised towards frontage) and hospitalized time. However, control group was not set up.Measurement data were expressed as Mean±SD and compared with t test; enumeration data were compared with Chi-square test and Mann-Whitney U test. P < 0.05 was regarded as significant difference. MAIN OUTCOME MEASURES: ① HSN disappearance; ② Numbers of body agnosia, left and right agnosia and difficult maintenance of supine position; ③ Correlation among therapeutic time, sitting-training time and hospitalized time. RESULTS: All 21 patients were involved in the final analysis. ① HSN disappearance: Among 21 cases, 2 patients had right HSN disappearance, 19 left HSN disappearance, 8 (38%, 8/21) HSN disappearance, and 13 (62%, 13/21) HSN remnant. Among 8 patients of HSN disappearance, symptoms of 4 cases lasted for 7 days and that of another 4 lasted for 8-12 days. ② Evaluation of HSN disappearance at various phases: Within 1 week, 19% (4/21) HSN patients had body agnosia, left and right agnosia; during recovery period, body agnosia of 20 cases was disappeared and that of 1 case was still survived. Within 1 week, cases with difficult maintenance of supine position were 67% (13/21), but 43% (17/21) during recovery period. ③ Analysis of effective factors on HSN disappearance and related intervention: At acute phase, HSN disappearance through sitting training lasted for (2.5±1.3) days, and remaining HSN symptoms were relieved for (5.0±3.7) days. There was significant difference between them (χ2 = 3.96, P = 0.039). The hospitalized time of patients with HSN disappearance and HSN remnant was (17.6±10.4), (16.2±4.9) days, but there was no significant difference between them (χ2 = 1.41, P = 0.679). Physiotherapy time of patients with HSN disappearance and HSN remnant was (11.1±7.5), (11.4±4.1) days, but there was no significant difference between them (χ2 = 1.05?熏 P = 0.894?雪. CONCLUSION: Early sitting training may play a possible role in HSN symptom disappearance of patients with stroke.

文摘BACKGROUND Arterial perforation has inevitably increased as endovascular treatments have become more common for intracranial large vessel occlusions,and even distal,medium vessel occlusions.A distal,medium vessel has a tortuous course and thinner wall compared to large arteries,making it more susceptible to damage.Here,we review the treatment strategies for arterial perforation during mechanical thrombectomy,and we report the case of a patient treated with gelfoam embolization.CASE SUMMARY A 63-year-old woman presented to the emergency department with sudden neurologic symptoms of right hemiparesis and global aphasia.The initial National Institutes of Health Stroke Scale score was 15.Computed tomography(CT)and CT angiography revealed hyperacute infarction and emergent arterial occlusion of the left middle cerebral artery M2-3 portion.During endovascular mechanical thrombectomy,arterial rupture occurred.The patient’s vital signs were stable,but delayed angiography showed persistent active bleeding.Therefore,selective embolization of the injured artery was performed using gelfoam.Subsequent left vertebral and internal carotid angiography was performed to confirm hemostasis.A localized subarachnoid hemorrhage(SAH)was confirmed on a follow-up CT scan.A repeated CT scan after 12 d showed resolution of the SAH,and rebleeding did not occur.CONCLUSION Rescue embolization with gelfoam could be considered an additional option in distal,medium vessel perforation.

文摘BACKGROUND Mechanical thrombectomy is the most effective treatment for great cerebral artery embolization within a set time window.Typically,an arteriogram does not show the localization of the stent after release and whether a thrombus is captured or not.Thus,improving the visualization of a stent in interventional therapy will be helpful for clinicians.AIM To analyze stent imaging findings to enhance clinicians’understanding of a special circumstance,wherein a Solitaire AB retrievable stent was visible during the imaging of a thrombus capture that improved the success rate of stent-based mechanical thrombectomy.METHODS This was a retrospective study with four acute ischemic stroke(AIS)patients who underwent stent-based mechanical thrombectomy.RESULTS Patient 1 was a 64-year-old man admitted after 5 h of confusion;angiography revealed basilar artery occlusion.We inserted a stent into the left posterior cerebral artery-P2 segment and visualized the expanded stent that successfully captured a thrombus.Patient 2 was a 74-year-old man admitted with confusion,which lasted approximately 3 h.Angiography revealed a left middle cerebral artery(MCA)-M1 segment occlusion.A stent was deployed in the distal M2 segment,and we could visualize the stent by capturing the thrombus.Patient 3 was a 74-year-old woman admitted after experiencing left hemiplegia for 3 h.We deployed a stent at the distal right MCAM2 segment,and the developing stent captured a large thrombus.Patient 4 was an 82-year-old man who presented with confusion for 3 h.A developing stent was placed in the distal left MCA-M1 segment,which captured a large thrombus and several fragmented thrombi.CONCLUSION To the best of our knowledge,this is the first report of stent imaging in patients with AIS.We demonstrated the usefulness and substantial potential of stent imaging in stent-based mechanical thrombectomy for AIS.

文摘Background:To compare the safety and effectiveness of direct mechanical thrombectomy and bridging therapy for stroke with acute anterior circulation large vessel occlusion within 4.5 hours of onset.Methods:Retrospectively collected from 66 patients with acute ischemic stroke admitted to the Department of Neurology of Tongliao Hospital and Xuanwu Hospital from August 2019 to November 2021 within 4.5 hours.According to the different recanalization methods,30 patients were assigned to the direct thrombectomy treatment group,and 36 patients in the bridging treatment group(i.e.,the intravenous thrombolysis bridging mechanical thrombectomy treatment group).The primary outcome measure was the neurological outcome at the onset of 90d.Secondary outcome measures were intraoperative vascular recanalization and reperfusion,and the US National Institute of Health Stroke Scale score at 24 hours after surgery.The primary safety indicators are intracranial hemorrhage,including symptomatic intracranial hemorrhage and non-symptomatic intracranial hemorrhage,and 90d mortality.Results:The direct thrombectomy group had lower body mass index,hypertension and baseline Alberta early computed tomography score than the bridging treatment group,and longer time from onset to visit than the bridging group(206.5(119.5,256.25)min vs.150.5(25.205,212.75)min),the above difference were statistically significant(P<0.05).There were no significant differences in successful vascular reperfusion(93%vs.89%),24 hours postoperative National Institute of Health Stroke Scale score(11(5,18)vs.11(5,20)),intracranial hemorrhage(11%vs.14%),symptomatic intracranial hemorrhage(7%vs.17%),90d mRS0 to 2 points(43%vs.36%)and 90d mortality(23%vs.22%)(P>0.05).Conclusion:Similar clinical efficacy and safety of direct mechanical thrombectomy and bridging therapy for acute anterior circulation large vessel occlusive stroke within 4.5 hours of onset,direct thrombectomy can be used as an alternative scheme for acute anterior circulation intracranial large artery occlusive stroke.
文摘Objective:Discussion and analysis of the effect of the early application of Tirofiban on acute ischemic stroke(AIS)after intravenous thrombolysis with urokinase.Method:The subjects of this study are 40 patients with AIS admitted at the Yibin Fourth People’s Hospital,of which were computer-randomized into a control group(20 cases,with regular urokinase intravenous thrombolysis therapy)and a research group(20 cases,combined with early Tirofiban treatment)from January 2018 to December 2022.The intervention outcomes between these two groups were compared and analyzed.Result:The blood platelet-related parameters before treatment had no statistical difference between the two groups(P>0.05),but the research group was higher than that of the control group after treatment(P<0.05).The Barthel index before treatment in both groups had no statistical difference(P>0.05),but the research group was higher than that of the control group after treatment(P<0.05).Conclusion:Early Tirofiban treatment for patients with AIS after intravenous thrombolysis with urokinase could effectively regulate the blood platelet-related parameters,hence improving treatment benefits and living capacity for patients,with definite clinical benefits.
文摘Ischemic stroke is an important disease leading to death and disability for all human beings, and the key to its treatment lies in the early opening of obstructed vessels and restoration of perfusion to the local infarcted area. Intravenous thrombolysis with tissue plasminogen activator (tPA) is one of the effective therapies to achieve revascularization, but it faces strict indications with a narrow therapeutic time window, and significantly increases the incidence of hemorrhagic transformation, HT, after reperfusion of the infarcted foci, which greatly reduces the incidence of patients with ischemic stroke. which significantly increases the incidence of hemorrhagic transformation (HT) after reperfusion of the infarcted focus, greatly reducing patient utilization and clinical benefit. Since the mechanism of HT has not been fully elucidated, and the related molecular mechanisms are complex and interactive, there is no specific and effective therapy to avoid the occurrence of HT. In this article, we focus on the research progress on the mechanism of HT after tPA intravenous thrombolysis in ischemic stroke patients from the aspects of vascular integrity disruption, oxidative stress, and neuroinflammatory response and the corresponding therapeutic strategies, in order to improve the safety and prognosis of tPA intravenous thrombolysis in the clinic.

文摘Objective To assess the effect and safety of bloodletting puncture at hand twelve Jing-Well points(HTWPs)in acute stroke patients with conscious disturbance.Methods In this multi-center and randomized controlled trial,360 patients suffered from ischemic or hemorrhagic stroke with conscious disturbance within 48 h from the onset of symptom were divided into bloodletting(180 cases)and control(180 cases)groups using a block randomization.Patients in both groups received routine Western medicine,and patients in the bloodletting group received additional bloodletting puncture at HTWPs on admission immediately before conventional treatment.The primary outcome measure was Glasgow Coma Scale(GCS)score and the secondary outcomes included blood pressure,respiratory rate and pulse rate.All variables were evaluated at baseline(before bloodletting),0(after bloodletting immediately),15,30,50 and 80 min post bloodletting.Results At 80 min post bloodletting,the proportion of patients with improved consciousness in the bloodletting group was greater than the control group(P<0.05).In the separate analysis of moderate consciousness disturbance subgroup,bloodletting therapy benefited ischemic patients,and improved the eye and language response of GCS score at 15,30,50,80 min post bloodletting(P<0.05 or P<0.01).No significant differences were observed regarding the secondary outcomes between two groups(P>0.05).Conclusion The bloodletting puncture at HTWPs was safe and could improve conscious levels of ischemic stroke patients,highlighting a first-aid intervention for acute stroke.
文摘Objective: To reveal the factors leading to delay in the evaluation processes of patients with suspected acute ischemic stroke at Yozgat City Hospital in Turkey and suggest potential solutions. Methods: Patients who visited the emergency service of Yozgat City Hospital between 1 April 2017 and 1 July 2017 and those hospitalized with a diagnosis of ischemic stroke, were included in this retrospective study. The clinical information of the patients was collected via hospital files and telephone interviews. In addition, the potential association between arrival time and the clinical parameters was investigated. Results: A total of 87 patients were included. The median arrival time to emergency service was 5 (IQR=9) h. Forty-four percent of patients arrived within the first 4.5 h from symptom onset. However, intravenous thrombolytic treatment was performed in only 7% of the patients. The median time from arrival to neuroimaging performing was 20.0 (IQR=34) min. Fifty-one percent of patients were screened within the first 20 min from arrival to emergency service. There was no association between arrival time and transfer method of the patients. Conclusions: The main problem regarding acute stroke care in our region may be inefficient use of emergency ambulance. This study provides basis for measures to shorten the arrival time.

文摘Diabetes mellitus and associated chronic hyperglycemia enhance the risk of acute ischemic stroke and lead to worsened clinical outcome and increased mortality. However, post-stroke hyperglycemia is also present in a number of non-diabetic patients after acute ischemic stroke, presumably as a stress response. The aim of this review is to summarize the main effects of hyperglycemia when associated to ischemic injury in acute stroke patients, highlighting the clinical and neurological outcomes in these conditions and after the administration of the currently approved pharmacological treatment, i.e. insulin. The disappointing results of the clinical trials on insulin(including the hypoglycemic events) demand a change of strategy based on more focused therapies. Starting from the comprehensive evaluation of the physiopathological alterations occurring in the ischemic brain during hyperglycemic conditions, the effects of various classes of glucose-lowering drugs are reviewed, such as glucose-like peptide-1 receptor agonists, DPP-4 inhibitors and sodium glucose cotransporter 2 inhibitors, in the perspective of overcoming the up-to-date limitations and of evaluating the effectiveness of new potential therapeutic strategies.
文摘BACKGROUND Argatroban is a novel direct thrombin inhibitor that has been used for treatment of acute ischemic stroke(AIS).To our knowledge,no systematic analysis has assessed the efficacy and safety of argatroban for treatment of AIS.AIM To evaluate the efficacy and safety of argatroban for treatment of AIS.METHODS Cochrane Library,Medline,PubMed,and Web of Science were searched to retrieve all studies associated with argatroban and AIS.Effective rate,adverse events rate,and 95%confidence intervals were calculated and pooled using metaanalysis methodology.RESULTS We only found four randomized controlled studies,comprising 354 cases with 213 in the argatroban group and 141 in the control group.Great heterogeneity was found in the four studies(c2=11.44,I2=74%,P=0.01).Subgroup analysis could not be performed because of the absence of detailed data.The two most recent studies showed acceptable heterogeneity(c2=1.56,I2=36%,P=0.21).Our analysis showed that argatroban was not more effective than the control therapy in the acute phase of ischemic stroke(Z=0.01,P=0.99).Argatroban did not increase the risk of bleeding compared with the control group(c2=0.37,I2=0%,P=0.54,Z=0.80,P=0.42).CONCLUSION Patients with AIS might not benefit from argatroban and combination therapy with argatroban does not increase bleeding tendency.
文摘Objective:To comprehensively evaluate the risk of recurrence after initial ischemic stroke,and to provide a relatively comprehensive reference for the prevention and control of stroke recurrence.Methods:CNKI,VIP,Wanfang,PubMed,Web of Science,Embase and other databases were collected to investigate the status of recurrence after initial ischemic stroke,the search period of which was from the establishment of databases to March 2019.And then quality evaluation and data extraction were carried out.The overall cumulative risks of stroke recurrence at 3 months,6 months,1 year,2 years and 5 years after initial ischemic stroke were calculated,and heterogeneity analysis was performed.Results:A total of 29 studies from 19 provinces(cities,autonomous regions)in China were included.The cumulative total sample size was 22484 cases,the cumulative recurrent sample size was 3309 cases.The pooled cumulative risk was 4.5%(95%CI:3.1-5.8)at 3 months,7.8%(95%CI:5.6-10.0)at 6 months,13.6%(95%CI:11.0-16.2)at 1 year,17.5%(95%CI:12.4-22.6)at 2 years and 30.9%(95%CI:20.2-41.7)at 5 years after initial ischemic stroke.Conclusions:The recurrence rate of acute ischemic stroke in China is high.It is recommended that all levels of medical and health departments strengthen the prevention and treatment of ischemic stroke recurrence to reduce the recurrence of ischemic stroke and improve the prognosis of patients.

文摘BACKGROUND Synthetic magnetic resonance imaging(MRI)MAGnetic resonance imaging compilation(MAGiC)is a new MRI technology.Conventional T1,T2,T2-fluidattenuated inversion recovery(FLAIR)contrast images,quantitative images of T1 and T2 mapping,and MAGiC phase sensitive inversion recovery(PSIR)Vessel cerebrovascular images can be obtained simultaneously through post-processing at the same time after completing a scan.In recent years,studies have reported that MAGiC can be applied to patients with acute ischemic stroke.We hypothesized that the synthetic MRI vascular screening scheme can evaluate the degree of cerebral artery stenosis in patients with acute ischemic stroke.AIM To explore the application value of vascular images obtained by synthetic MRI in diagnosing acute ischemic stroke.METHODS A total of 64 patients with acute ischemic stroke were selected and examined by MRI in the current retrospective cohort study.The scanning sequences included traditional T1,T2,and T2-FLAIR,three-dimensional time-of-flight magnetic resonance angiography(3D TOF MRA),diffusion-weighted imaging(DWI),and synthetic MRI.Conventional contrast images(T1,T2,and T2-FLAIR)and intracranial vessel images(MAGiC PSIR Vessel]were automatically reconstructed using synthetic MRI raw data.The contrast-to-noise ratio(CNR)values of traditional T1,T2,and T2-FLAIR images and MAGiC reconstructed T1,T2,and T2-FLAIR images in DWI diffusion restriction areas were measured and compared.MAGiC PSIR Vessel and TOF MRA images were used to measure and calculate the stenosis degree of bilateral middle cerebral artery stenosis areas.The consistency of MAGiC PSIR Vessel and TOF MRA in displaying the degree of vascular stenosis with computed tomography angiography(CTA)was compared.RESULTS Among the 64 patients with acute ischemic stroke,79 vascular stenosis areas showed that the correlation between MAGiC PSIR Vessel and CTA(r=0.90,P<0.01)was higher than that between TOF MRA and CTA(r=0.84,P<0.01).With a degree of vascular stenosis>50%assessed by CTA as a reference,the area under the receiver operating characteristic(ROC)curve of MAGiC PSIR Vessel[area under the curve(AUC)=0.906,P<0.01]was higher than that of TOF MRA(AUC=0.790,P<0.01).Among the 64 patients with acute ischemic stroke,39 were scanned for traditional T1,T2,and T2-FLAIR images and MAGiC images simultaneously,and CNR values in DWI diffusion restriction areas were measured,which were:Traditional T2=21.2,traditional T1=-6.7,and traditional T2-FLAIR=11.9;and MAGiC T2=7.1,MAGiC T1=-3.9,and MAGiC T2-FLAIR=4.5.CONCLUSION The synthetic MRI vascular screening scheme for patients with acute ischemic stroke can accurately evaluate the degree of bilateral middle cerebral artery stenosis,which is of great significance to early thrombolytic interventional therapy and improving patients’quality of life.
