Hydrocephalus is a common complication of aneurysmal subarachnoid hemorrhage. Numerous studies have dealt so far with the triggering cause of the chronic cerebrospinal fluid (CSF) absorptional and circulatory disorders. Despite the fact that these studies gave several different explanations, most of them agreed on the fact that the obstruction of CSF pathway has a crucial role in the development of the clinical feature. ⋯ The studies have shown that the risk of incidence of chronic hydrocephalus were higher in men and in case of severe clinical state with severe SAH. The disturbed CSF circulation and/or absorption were positively correlated with consuming alcohol and hypertension, while smoking did not affect it. The rate of the incidence of chronic hydrocephalus among our patients was lower (5.8%) compared to the results of other studies (7-40%) suggests that disturbance of CSF circulation and/or absorption may be avoided in the majority of cases by continuous external ventricular or lumbar CSF drainage, which is applied routinly.
