蛛网膜下腔出血后脑血管痉挛发病机制的研究新进展
Chinese Journal of Neuromedicine（2013）
Abstract
蛛网膜下腔出血(subarachnoid hemorrhage,SAH)后,患者常伴有脑血管痉挛(cerebral vasospasm,CVS),出血后4～14d为高峰期.CVS导致脑组织局部缺血,进而引起神经功能障碍.近年来有大量文献资料和实验数据表明SAH后CVS的发生率约30％～80％,约46％的患者出现临床症状,是导致SAH患者死亡或致残的主要并发症[1].其病因机制复杂,研究表明多种因素与CVS的发生有关.本文就SAH后CVS发病机制的研究进展综述如下.
