66例蛛网膜下腔出血全脑血管造影分析

Character of cerebral angiography of subarachnoid hemorrhage:An analysis of 66 cases

目的:研究自发性蛛网膜下腔出血(SAH)全脑血管造影(DSA)的特征。方法:对66例SAH患者的临床表现、颅脑CT、脑DSA检查等资料进行分析。结果:SAH的病因主要以颅内动脉瘤为主,且主要以中小型动脉瘤为主,旋转DSA可以清楚显示动脉瘤在立体空间中的实际解剖关系;CT平扫的出血量不一定跟动脉瘤的大小相平行;青壮年患者血管痉挛程度较年龄偏大的患者重。结论:SAH以颅内动脉瘤破裂出血为主,脑DSA能明确动脉瘤的部位、形态、大小,是SAH病因学检查的首要手段。

Objective：To study the character of cerebral angiography for spontaneous subarachnoid hemorrhage（SAH）.Methods： 66 patients with SAH were reviewed retrospectively in terms of clinical symptoms,cerebral CT and cerebral angiography.Results： The major etiology of SAH was identified as intracranial aneurysm,with medium-sized or small-sized intracranial aneurysm as majority. Rotary digital subtraction angiography showed the special relationship of the intracranial aneurysm to anatomic position.The amount of subarachnoid blood from computed tomography（CT） scan were not necessarily matched with the size of aneurysm.The seriousness of cerebral vasospasm in young adults was greater compared with the older.Conclusion： The intracranial aneurysm is the most common cause for SAH,cerebral angiography can make accurate diagnosis of the intracranial aneurysm to anatomic position,appearance and size,and it is chief instrument to ascertain the cause of subarachnoid hemorrhage.
