蛛网膜下腔出血时玻璃膜下出血的发生机理及临床意义的探讨

Study on clinical valuation of the SHH for SAH.

我们五年间收治的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、颅内压更高,死亡率亦增加。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。

The clinical valuation of subhyaloid hemorrhage (SHH)in 609 cases with subarachnokl hemorrhage (SAH) was studied by analysing 62 patients with SHH (in both eyes in 35 cases and one eye in 27 cases). A comparision study between theSHH group and non-SHH group was made, showing that the clinical symptoms were more severe, had higher intracranial pressure and higher mortality in the SHH group. The autopsy showed that in the 6 cases of SHH with one eye the damaged eye was located on the same side with ruptured intracranial aneurysm.
