ABSTRACT

Objective To systematically analyze the risk factors for de1ayed cerebral vasospasm after aneurysm subarachnoid hemorrhage in order to provide evidence for prevention and treatment of the disease .Methods Articles of risk factors for de1ayed cerebral vasospasm after aneurysm subarachnoid hemorrhage from VIP ,CBM ,CNKI ,Wangfang and pubmed ,springlink ,highwire database ,and correlated indexes were extracted for Meta‐analysis by using RevMan 5 .1 .Results Thirteen articles were selected . The heterogeneity of all data was equilibrium ,and used fixed effects model .The difference showed statistical significance in the his‐tory of hypertension ,Fisher > Ⅱ ,age>50 years and the posterior circulation aneurysm (P0 .05) .The symmetry of funnel plots prompted no publication bias .Conclusion Patients with history of hypertension ,Fisher > Ⅱ ,age< 50 years and the posterior circulation aneurysm are at higher risk of de1ayed cerebral vasospasm ,strengthen close monitoring and management are crucial in these patients .
