蛛网膜下腔出血(subarachnoid hemorrhage,SAH)后脑血管痉挛(cerebrovasospasm,CVS)是患者病残和死亡的主要原因[1]。SAH后CVS分为早期痉挛和迟发痉挛(delate cerebrovasospasm,DCVS)。前者常见于起病后,历时短暂(数分钟后数小时)。后者多发生于痉挛后5~15 d。CVS是SAH后最严重
Cerebrovascular vasospasm (CVS) after subarachnoid hemorrhage (SAH) is a major cause of morbidity and mortality in patients [1]. CVS after SAH is divided into early spasm and delayed spasm (delate cerebrovasospasm, DCVS). The former is common in onset, lasted a short time (a few hours after a few hours). The latter occurred in 5 to 15 days after spasticity. CVS is the worst after SAH
