分析150例蛛网膜下腔出血（SAH）患者数字减影血管造影术（DSA）检查结果。结果示颅内动脉瘤、血管畸形及动脉炎为SAH主要病因，分别占36．67％，12．67％，8．6％。脑血管造影正常者41．3％，与SAH后病变本身变化或隐匿性血管病变未能被显示有关。早期脑血管DSA检查有利于颅内血管病变的及时诊断与治疗，并可减少SAH并发症的发生。
Analysis of digital subtraction angiography (DSA) findings in 150 patients with subarachnoid hemorrhage (SAH). The results showed that intracranial aneurysms, vascular malformations and arteritis were the major causes of SAH, accounting for 36.67%, 12.67% and 8.6% respectively. Cerebral angiography was normal 41.3%, with changes in SAH after the disease itself or occult vascular disease can not be displayed. Early cerebral vascular DSA examination is conducive to timely diagnosis and treatment of intracranial vascular lesions, and can reduce the occurrence of SAH complications.
