摘　　要：目的探讨血管超声在单侧大脑中动脉(MCA)闭塞行颞浅动脉-大脑中动脉(STA-MCA)血管旁路移植术后的脑血流动力学动态评估中的应用。方法回顾性连续纳入苏州大学附属第一医院神经外科经DSA确诊为单侧MCA闭塞且行STA-MCA血管旁路移植术患者109例。入院24 h内完成患者临床资料收集,包括年龄、性别、体质量指数和卒中高危因素(包括高血压病、高脂血症、糖尿病、吸烟和饮酒史、心房颤动)、临床表现[近6个月内;非特异性症状(头晕、记忆力减退、反应迟钝等)、短暂性脑缺血发作、卒中]、血生化指标(低密度脂蛋白胆固醇、高密度脂蛋白胆固醇、三酰甘油、总胆固醇、空腹血糖、超敏C反应蛋白)、入院时美国国立卫生研究院卒中量表(NIHSS)评分。运用彩色多普勒超声(CDU)和经颅彩色多普勒超声(TCCD)在患者术前及术后不同时间段(术后4~7 d及术后1、3、6、12个月)评估STA的血流动力学参数,分析桥血管的血流通畅性以及颅内血流动力学改变,并对术后12个月CDU和DSA检查桥血管通畅情况的结果行一致性检验。根据术后12个月DSA检查结果将患者分为桥血管通畅组和非通畅组(狭窄或闭塞),比较两组各时间段STA主干即桥血管颅外段、入颅段和颅内段内径(D)及血流动力学参数包括收缩期峰值流速(PSV)、舒张期末流速(EDV)、阻力指数(RI)、搏动指数(PI)、时间平均流速(TAMV)和时间峰值流速(TAPV)并计算STA主干时间平均流量(TAMV flow)、时间平均峰值流量(TAPV flow)。于术前1~3 d及术后12、18个月分别行头部CT、主动脉弓上CT血管成像及全脑CT灌注(CTP)检查以观察患者脑灌注改变情况,术后1~2 d行头部CT观察术区有无新发出血及缺血灶。分别比较桥血管通畅组和非通畅组术后12、18个月与术前1~3 d的CTP参数,以及两组之间CTP参数的差异。术后12、18个月门诊复诊时,采用改良Rankin量表(mRS)评�Objective To explore the dynamic changes in cerebral hemodynamics in patients with unilateral middle cerebral artery(MCA)occlusion after superficial temporal artery(STA)-MCA bypass surgery.Methods One hundred and nine patients diagnosed with unilateral MCA occlusion by DSA who underwent STA-MCA bypass surgery were retrospectively included in the Department of Neurosurgery of the First Affiliated Hospital of Soochow University.Clinical data of patients were collected within 24 hours after admission,including age,sex,body mass index,stroke risk factors including hypertension,hyperlipidemia,diabetes,smoking,drinking history and atrial fibrillation,clinical manifestations(within the last 6 months;nonspecific symptoms[dizziness,memory loss,unresponsiveness,etc.],transient ischemic attack,and stroke),blood biochemical markers(low density lipoprotein cholesterol,high density lipoprotein cholesterol,triglyceride,total cholesterol,fasting blood glucose,and hypersensitive C-reactive protein),and National Institutes of Health stroke scale(NIHSS)score at admission.Color Doppler ultrasound(CDU)and transcranial color coded Doppler(TCCD)ultrasound were used to evaluate the hemodynamic parameters of STA before and at different periods after surgery(4-7 days and 1,3,6,12 months after surgery)to analyze the patency of bypass arteries and intracranial hemodynamic changes,and to check the consistency of the results of the bridge artery patency at 12 months postoperatively by CDU and DSA,consistency test was performed.According to the results of the DSA examination 12 months after surgery,the patients were divided into the bypass artery patency group and the non-patency group(stenosis or occlusion).The hemodynamic parameters at the trunk of STA,namely the extracranial segment,transcranial,and intracranial part of the bypass arteries,were compared between the two groups.It included inner diameter(D),peak systolic velocity(PSV),end-diastolic velocity(EDV),resistance index(RI),pulsation index(PI),time-averaged mean velocity(TAMV),time-a
