Risk factors correlated with hydrocephalus after aneurysmal subarachnoid hemorrhage

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.
