蛛网膜下腔出血时玻璃膜下出血的发生机理及临床意义

我们5年间收治的609例SAH中有62例并发SHH，占10.2%，其中双眼SHH35例，单眼SHH27例，与无SHH的SAH患者相比，SHH组临床症状及体征重，颅内压高的多，死亡率亦高，说明SHH是重症SAH的体征之一。本组资料支持SHH是蛛网膜下腔的动脉血直接沿视神经鞘向眼底方向的扩延，条件是颅内压要在短时间内达到一定程度，单侧的SHH对SAH的病因具有定位和定性意义。

STUDY ON CLINICAL VALUATION OF THE SHH FOR SAH

The clinical valuation of SHH for the SAH was discussed by analysing for 62 patients with SHH (in both eyes in 35 cases and in only one eye in 27) who were numbers of the 609 cases with SAH. The results which had made a comparision between the SHH group and no SHH group show that the clinical symptoms were severer. the intracranial pressure was highter and the mortality in the SHH group was more than the no SHH group. It was demonstrated the SHH of 6 cases in only one eye located on the same side with ruptured inteacranial aneurysm by autopsy in this paper.
