The impact of endovascular treatment on cerebral aneurysm outcome at Groote Schuur Hospital
Abstract
Design. Retrospective cohort study. The first cohort included cerebral aneurysm patients seen between 1994 and 1998 when only surgical treatment was available. The second cohort consisted of a group treated using both surgical and endovascular methods between 2002 and 2004.
Subjects. Patients with ruptured and unruptured aneurysms were included in the study.
Outcome measures. The Glasgow Outcome Score (GOS) was used to assess outcome. The primary comparator between groups was major disability (GOS 3 and 2) and death (GOS 1).
