自发性蛛网膜下腔出血(SAH)多为脑底或脑表面血管病变(如先天性动脉瘤、脑血管畸形、高血压脑动脉硬化所致的微动脉瘤)破裂,血液渗入蛛网膜下腔所致的急危重症脑血管病之一,其占急性脑卒中的10%左右,病死率高达45%,存活着也可致明显的神经功能损害,严重影响患者预后[1]。脑积水为其常见的并发症之一,本文通过对动脉瘤性SAH后82例患者采取单用尼莫同及尼莫同联合脑脊液置换加鞘内注射两种治疗方法 Spontaneous subarachnoid hemorrhage (SAH) are mostly cerebral or cerebral surface lesions (such as congenital aneurysms, cerebrovascular malformations, hypertensive cerebral arteriosclerosis caused by aneurysm) rupture, blood penetration into the subarachnoid space As a result of acute and critical cerebrovascular disease, which accounts for about 10% of acute stroke, the mortality rate as high as 45%, survival can also cause significant neurological damage, seriously affecting the prognosis of patients [1]. Hydrocephalus is one of its common complications, this article through the aneurysmal SAH after 82 patients with nimodipine alone and nimotone combined with cerebrospinal fluid replacement plus intrathecal injection of two kinds of treatment
