Abstract

To preliminarily explore the clinical characteristics and surgical outcomes of intracranial aneurysm. The data of 3322 cases of intracranial aneurysm from January 1955 to July 2009 were collected at our hospital for analysis. The clinical characteristics and surgical outcomes of patients with intracranial aneurysm were assessed. The surgical patients were divided into 2 groups by the date of admission: group A and group B. Such clinical characteristics as age, gender and Hunt-Hess grade at admission and first presentations were analyzed. The surgical outcomes were assessed by comparing the surgical complications between two groups. Intracranial aneurysms were commonly diagnosed between 38 and 54 years old. Hemorrhage (84.89%), mass effect (8.13%) and non-hemorrhagic headache (5.18%) were the three initial common presentations and the male-to-female ratio was 0.875:1. There was no significant statistical difference in age distribution and gender ratio between two groups. According to the Hunt-Hess grade, the percentage of grades II, III and IV was lower in group B while the percentage of grades 0 and I higher than group A. No significant difference was found in the overall incidence of major post-operative complications between ...Continue Reading
