动脉瘤破裂后的蛛网膜下腔出血引起脑缺血是常见且危险的并发症,可依据病人的意识水平下降和/或出现神经系统定位体征,无再出血的迹象而确定,几乎所有病例都发生于初次出血后两周内。文献中迟发性脑缺血的发病率为25-42%,虽然迟发性脑缺血常见,但其病因不清,可能与脑动脉血管痉挛有关,但其确切关系尚不明,流到蛛网膜下腔的血液及其代谢产物可能引起血管痉挛和缺血。为验证这一推想,本文报道一组经动脉造影证实无动 Subarachnoid hemorrhage after ruptured aneurysm is a common and dangerous complication of cerebral ischemia and can be based on a decrease in patient’s level of consciousness and / or neurological signs, with no evidence of rebleeding, and almost all cases Occurs within two weeks after initial bleed. The incidence of delayed cerebral ischemia in the literature is 25-42%, although delayed cerebral ischemia is common, but the etiology is unclear, may be related to cerebral vasospasm, but its exact relationship is not clear, flow to the cobweb Subcapsular blood and its metabolites may cause vasospasm and ischemia. To verify this hypothesis, this article reports a group confirmed by arteriography without motion
