本文分析７４例经腰穿证实的自发性蛛网膜下腔出血（ＳＡＨ）及２０例经ＣＴ检查为外伤性ＳＡＨ的ＣＴ和临床表现；着重探讨了自发性ＳＡＨ的病因诊断，笔者认为常见原因是颅内动脉瘤、脑动静脉畸形（ＡＶＭ）、高血压动脉硬化。而动脉瘤、ＡＶＭ最常见，占查出原因的７４％，ＣＴ像上有ＳＺＨ表现的又以动脉瘤最常见，根据ＣＴ像上ＳＡＨ的分布及附近并发的脑内血肿可推断动脉瘤破裂的位置。本文还概括了ＳＡＨ典型的临床表现和常见并发症。最后简单分析了ＣＴ检查无ＳＡＨ表现的原因。
This article analyzes 74 cases of lumbar puncture confirmed spontaneous subarachnoid hemorrhage (SAH) and 20 cases of traumatic SAH by CT CT and clinical manifestations; emphatically discussed the etiological diagnosis of spontaneous SAH, I think the common cause is Intracranial aneurysms, cerebral arteriovenous malformations (AVMs), hypertensive arteriosclerosis. The aneurysm, AVM most common, accounting for 74% of the reasons identified, the CT images of SZH performance and aneurysm is the most common, according to the CT image on the distribution of SAH and nearby intracerebral hematoma can be concluded aneurysm rupture position. This article also summarizes the typical clinical manifestations of SAH and common complications. Finally, a simple analysis of the reasons for CT without SAH performance.
