摘　　要：目的对１０００例自发性蛛网膜下腔出血（ＳＡＨ）的ＣＴ表现与血管造影进行回顾性对照，对出血部位和病因进行分析。方法全部病例经ＣＴ与ＤＳＡ检查，观察内容是ＳＡＨ的病因及病变位置。结果１０００例自发性蛛网膜下腔出血的病例中，ＤＳＡ显示有动脉瘤５４７例，血管畸形２８９例，动脉硬化１６１例，其他３例。ＣＴ诊断动脉瘤所致出血４６１例，血管畸形２５９例，动脉硬化１５１例。结论ＣＴ对ＳＡＨ定性、定位有一定意义，对于急诊病人的治疗、手术引流及血管造影的选择具有很大的参考价值。Objective To investigate on the site and causes of 1 000 cases of spontaneous subarachnoid hemorrhage(SAH) by CT and compared with DSA retrospectively. Methods All patients were examined by CT and DSA, and the etiology and site of lesion were identified. Results The causes of SAH diagnosed by DSA were: cerebral aneurysm 461 cases,vascular malformations 259 and arteriosclerosis 161,other causes 3. Whereas the causes diagnosed by CT were cerebral aneurysm 461,vascular malformations 259,arteriosclerosis 151. Conclusions The results suggested that CT is helpful in identifying the cause and site of spontaneous SAH, and is a useful guide to selection of operative drainage and angiography in emergency.
