动脉粥样硬化相关性缺血性脑血管病408例数字减影血管造影分析

目的 采用数字减影血管造影(DSA)探讨颅内外供血动脉中重度狭窄或闭塞的临床特点.方法 回顾性分析408例动脉粥样硬化相关性缺血性脑血管病患者的DSA资料;分为脑梗死组和短暂性脑缺血发作(TIA)组.结果 408例患者中,247例(60.5%)存在脑供血动脉中重度狭窄或闭塞,共存在398处中重度狭窄或闭塞,主要累及颈内动脉起始段(23.4%)、大脑中动脉M1段(17.8%)、椎动脉V1段(16.8%);青年组和中年组单纯颅内动脉累及分别为5例(71.4%)和40例(54.8%),均显著高于老年组(49例,29.3%),差异有统计学意义(P＜0.05);单纯颅内动脉累及组的平均年龄(60.2±10.1)岁]显著低于单纯颅外动脉累及组(66.9±8.9)岁]和颅内外动脉均累及组(64.3±9.1)岁],差异有统计学意义(P＜0.05);颅内外动脉均累及组的胆固醇水平(5.0±1.2) mmol/L]显著高于单纯颅外动脉累及组(4.4±1.0 )mmol/L],差异有统计学意义(P＜0.05);单纯颅外动脉累及组合并嗜烟史者65例(59.1%),显著高于单纯颅内动脉累及组(37例,40.2%),差异有统计学意义(P＜0.01).结论 颈内动脉起始段、大脑中动脉M1段、椎动脉V1段为脑供血动脉中重度狭窄或闭塞的好发部位;随着年龄的增长,颅外动脉受累所占比例明显增多;嗜烟史对颅外动脉影响更大.

Analysis of 408 Cases of Atherosclerosis-related Ischemic Cerebrovascular Disease by Digital Subtraction Angiography

Objective To analyze the clinical characteristics of cerebral artery Moderate and severe stenosis or occlusion by Digital subtraction angiography(DSA).Methods The data of DSA of 408 patients with atherosclerosis-related ischemic cerebrovascular disease were analyzed Retrospectively,which were divided into cerebral infarction group and transient ischemic attack(TIA) group.Results 408 patients,247 cases(60.5%) had moderate and severe cerebral artery stenosis or occlusion,there is a total of 398 moderate and s...
