Abstract
One-quarter of all cerebral aneurysms affect the posterior communicating artery. The clinical course typically involves subarachnoid hemorrhage and oculomotor nerve palsy. The objective of this study was to apply the de Aguiar and colleagues’ anatomicosurgical classification of posterior communicating artery aneurysms to a series of ruptured and incidental aneurysms treated at a single center and ascertain whether correlations exist between this classification and surgical outcomes (successful or failed occlusion). A single-center, retrospective cohort study based on imaging data was carried out between 2005 and 2010. Patients were allocated into 2 groups depending on aneurysm presentation (acutely ruptured or incidental). In this series, posterior communicating artery aneurysms were 4 to 5 times more common in women than in men, and type II (temporal) aneurysms were those most frequently found. The worst prognosis in the acute bleeding group was seen in cases with fetal variant circulation. The overall prognosis was poorer for temporal aneurysms, particularly those with a higher Hunt and Hess scale grade. Unruptured aneurysms were associated with better outcomes after surgical treatment.
