蛛网膜下腔出血后脑血管痉挛发生机制及治疗的研究进展

脑血管痉挛（CVS）是蛛网膜下腔出血（SAH）后并发的一种危险病理生理状态。CVS时因局部脑血管收缩使受累脑组织区域血供减少，从而引起缺血缺氧性神经功能损害而使患者致残，致亡、影响预后的主要原因。如今，伴随广大学者对其发生、发展机制的深入研究，以及临床工作中相关特异性药物的广泛应用，人们对SAH患者出血后CVS的发生、以及其他一系列不良事件的预防和治疗方案亦日趋成熟，本文就其发生、发展机制以及目前的治疗方式做一简单系统性回顾与展望，希望能为广大临床医师对于相关的临床选择提供借鉴。

Progress for occurring mechanisms and prognostic therapy status of cerebral vasospasm after subarachnoid hemorrhage

Cerebral vasospasm （CVS） is one of the most dangerous pathophysiological state after subarachnoid hemorrhage （SAH）. It can cause ischemic neurological impairments, deficits, even death due to its infection on reducing local cerebrovascular blood flow, which results in vasoconstrictions in the affected regions. It＇ s also one of the main factors for the rehabilitation in the prognosis. At present time, along with the prognostic researching on its occurrence and development, beside more specific drugs applied in practical clinic works, it is more matured to choose the optimize therapeutic regimen for CVS after SAH. This review summarized the recent status on occurring mechanisms and prognostic therapy status of cerebral vasospasm after subarachnoid hemorrhage, in the hope of expressing some directive plays for neurologic work.
