缺血性脑卒中患者的数字减影脑血管造影的研究

目的探讨缺血性脑卒中患者全脑血管造影的特点。方法对243例缺血性脑卒中患者进行全脑血管造影检查,回顾性分析脑动脉颅内动脉狭窄、颅外动脉狭窄的发生率及其分布情况。结果在243例缺血性脑卒中180例（74.07%）存在脑动脉狭窄或闭塞,前循环动脉狭窄或闭塞82例（45.46%）,后循环52例（28.89%）,前后循环均有46例（25.56%）。颅内动脉狭窄或闭塞48例（26.67%）,颅外动脉86例（47.78%）,颅内、外动脉均有46例（25.56%）。180例中共发现狭窄血管356支,单支血管病变82例,多支血管病变98例。颅外血管狭窄以颈内动脉颅外段最多,颅内血管狭窄以椎动脉颅内段和大脑中动脉为多。结论脑血管造影可以准确地评价缺血性脑卒中患者脑动脉狭窄的分布情况及其程度,为临床提供了诊治依据。

Study of digital subtraction angiography in patients with ischemic cerebrovascular stroke

Objective To investigate the characterisitics of digital subtraction angiography（DSA）in patients with ischemic cerebrovascular stroke.Methods 243 patients with ischemic cerebrovascular stroke were detected by DSA in order to analyze the distribution and the occurrence of intra-extracranial vascular.Results The 243 cases of ischemic cerebrovascular stroke,the rate of intra-extracranial vascular stenosis was 74.07%（180 cases）.45.46%（82 cases）was in anterior circulation and 28.89%（52 cases）was in the posterior circulation and 25.56%（46 cases）was in the anterior-posterior circulation.26.67%（48 cases）was of intracranial stenosis,47.78%（86 cases）was of extracranial stenosis and 25.56%（46 cases）was both.As for incidence of single or dual stenosis among 365 vessels with arteriostenosis,single stenosis amounted to 82 cases and dual to 98 cases.Extracranial stenosis occurred most in extracranial part of internal carotid artery.Intracranial stenosis more occurred in middle cerebral artery.Conclusions DSA can be accurate evaluation the distribution and degree of cranial vessels stenosis.So as to provide basement for the clinical treatment.
