缺血性脑血管病全脑血管造影分析

目的 研究不同类型缺血性脑血管病全脑血管造影的影像学特点及临床意义.方法 选择312例脑梗死和短暂性脑缺血发作(TIA)患者行全脑数字减影血管造影(DSA)检查,比较颅内动脉及脑动脉颅外段闭塞或狭窄的分布情况.结果 DSA显示颈内动脉系统及椎-基底动脉系统脑梗死,狭窄或闭塞均以颅内动脉为主[分别占59.57%(56/94)和61.90%(26/42)];而颈内动脉系统TIA以颅内动脉闭塞或狭窄为主(68.75%,22/32).椎一基底动脉系统TIA以脑动脉颅外段闭塞或狭窄为主(61.70%,29/47).结论 颅内动脉闭塞或狭窄是脑梗死(包括颈内动脉系统及椎-基底动脉系统)及颈内动脉系统TIA的主要病因,脑动脉颅外段闭塞或狭窄是椎-基底动脉系统TIA的主要病因.

The analysis of cerebral angiography of the ischemic cerebrovaseular diseases

Objective To study the nlanifestation and the clinical significance of the cerebral angiography of the isehemic cerebrovascular diseases.Methods Digital sublraction angiography(DSA)was taken in 312 patients with cerebral infarction and transient ischemic attack(TLA).The distribution of the lesion in the extra/intracranial arteries was compared.Results Cerebral angiography showed that the stenosis and occlusion was dominant in the intracranial arteries at the cerebral infarction in the internal carotid artery system and vertebrobasilar artery system[59.57%(56/94)and 61.90%(26/42)].TIA of internal carotid artery system was mainly because of stenosis of intracranial arteries (68.75%,22/32).TIA of vertebrobasilar artery system was mainly because of stenosis of extracranial arteries(61.70%,29/47).Conclusions The diseases of the intracranial arteries are the main causes of cerebral infarction(including internal carotid artery system and vertebrobasilar artery system) and TIA of internal carotid artery system. The diseases of the extracranial arteries are main causes of TIA of vertebrobasilar artery system.
