Abstract

Posterior cerebral artery (PCA) aneurysm is a rare disease, and has some distinctive features compared with aneurysms located elsewhere. This study is to investigate results of the management and characteristics of posterior cerebral artery aneurysm. Between 1996 and 2005, we treated 8 patients (4 male, 4 female) via endovascular or surgical approach. Six patients underwent endovascular treatment and two were treated with open surgery. The Glasgow Outcome Scale (GOS) was used for estimating the results. Five patients had ruptured PCA aneurysms and three had unruptured aneurysms. The locations were one case of P1 branch, two cases of P1-P2 junction, four cases of P2-P3 junction and one case of distal P4 branch. Among 8 patients, five had good recovery, two had a moderate disability and another one was expired due to rebleeding. Optimal treatment of PCA aneurysms is able to perform via surgical or endovascular approach. Endovascular treatment is effective and an alternative method for PCA aneurysm because of the difficulty and several complications of surgical approach.
