动脉瘤性蛛网膜下腔出血后慢性脑积水形成相关危险因素分析

Risk factors correlated with hydrocephalus after aneurysmal subarachnoid hemorrhage

摘要:

目的：探讨动脉瘤性蛛网膜下腔出血（aSAH）后慢性脑积水形成的危险因素。方法：回顾分析170例aSAH患者临床资料，应用出血后3周的CT评价aSAH后慢性脑积水；先将可能的危险因素与脑积水之间行显著性检验，再用多元回归加以明确，得到回归方程。结果：aSAH后慢性脑积水易患因素依次为入院时较高Hunt-Hess分级（P=0.006）、反复多次出血（P=0.007）、高龄（P=0.010）。结论：aSAH后慢性脑积水形成为多因素共同作用的结果。

Abstract:

Objective: To study the risk factors of chronic hydrocephalus after aneurismal subarachnoid hemorrhage(aSAH).Methods: The clinical data of 170 patients with aSAH were respectively studied.Hydrocephalus was confirmed on the basis of the findings of CT scans 3 week after aSAH.Univariate analysis was performed to assess the relationship between the possible risk factors and the occurrence of hydrocephalus.Those factors statistically associated with the occurrence of hydrocephalus were further analyzed using the logistic regression analysis.Results: There were three risk factors for the development of hydrocephalus after aSAH:Hunt-Hess grade(high) at admission(P=0.006),repeated SAH(P=0.007) and increasing age(P=0.010).Conclusions: The development of hydrocephalus after aSAH is multifactorial.
