Abstract

Surgical procedures for aneurysmal subarachnoid hemorrhage (SAH) are increasing among the elderly as the population ages. Chronic shunt-dependent hydrocephalus is a recognized complication of SAH. The aim of this study was to identify predictive factors for the development of shunt-dependent hydrocephalus among elderly patients with SAH. We retrospectively studied 878 patients, including 275 patients ? 65 years old, with SAH treated between 2005 and 2015 to identify factors contributing to the development of shunt-dependent hydrocephalus. The relationships between shunt-dependent hydrocephalus and the causative factors were analyzed using univariate and multivariate analysis; the causative factors were based on the results of previous studies. In the 878 patients with SAH, there was a significant difference in the incidence of shunt-dependent hydrocephalus between patients < 65 years old and those ? 65 years old (p=0.021). In the 275 patients ? 65 years old, the following were associated with shunt-dependent hydrocephalus on univariate analysis: 1) Hunt and Hess grade (p=0.005), 2) Fisher grade (p < 0.001), 3) intraventricular hemorrhage (p < 0.001), 4) acute hydrocephalus (p=0.003), 5) aneurysm location (p=0.001), and 6) exter...Continue Reading
