缺血性脑血管病患者脑主要供血动脉狭窄分布的DSA分析

目的探讨缺血性脑血管病(ICVD)患者脑主要供血动脉狭窄分布特征。方法对2007-2009年诊治的脑主要供血动脉狭窄92例ICVD患者的临床和DSA资料进行回顾性分析。结果脑主要供血动脉颅外段病变发生率(82.6%)高于颅内段动脉(66.3%);多支动脉及前后循环同时病变的发生率较高(79.3%、57.6%);颈动脉系统常见狭窄部位是颈内动脉颅外段(57.6%)、大脑中动脉(34.8%),椎基底动脉系统常见狭窄部位是椎动脉颅外段(57.6%)、椎动脉颅内段(20.7%)。可干预危险因素越多,颅外合并颅内动脉狭窄的发生率越高,但无显著性差别(χ2=7.1;P=0.069)。结论 ICVD患者以颅外段动脉狭窄多见;颈动脉系统狭窄好发于颈内动脉颅外段、大脑中动脉,椎基底动脉系统好发于椎动脉颅外段。伴不同可干预危险因素组颅内合并颅内动脉狭窄的发生率无显著差异。

Analysis of digital subtraction angiography of distribution of main cerebral feeding artery stenosis in patients with ischemic cerebrovascular disease

Objective To investigate the distribution characteristics of main cerebral feeding artery stenosis in patients with ischemic cerebrovascular disease(ICVD).Methods The clinical and DSA data of 92 ICVD patients who had main cerebral feeding artery stenosis confirmed by DSA within 2007～2009 were retrospectively studied.Results The incidence of stenosis of extracranial arteries of main cerebral feeding arteries(82.6%)was higher than that of intracranial arteries(66.3%).The incidence of multiple artery stenosis(...
