Microsurgical Experience of Posterior Circulation Aneurysms

Abstract

Aneurysms arising from the posterior circulation are relatively uncommon and are regarded as the most difficult aneurysms for surgical management because of its confined surgical space and complicated blood vessels around brain stem. Twenty cases of posterior circulation aneurysm were operated between Jan. 1984 and July, 1987. At the same period total surgically treated aneurysms were 181 cases. Among 20 cases, aneurysms at the basilar artery bifurcation were 12 cases, 4 cases at the SCA-basilar artery, 3 cases at the distal PICA and one case was at the PCA(P2-P3). Five patients had multiple aneurysms and one patient had concomitant arteriovenous malformation. For the operative management of these 20 cases, direct neck clipping was done in 16 cases and wrapping was done in 4 cases. Surgical outcome was evaluated: "good" in 10 cases, "fair" in 3 cases, "poor" in 6 cases and one patient expired. Surgical consideration of posterior circulation aneurysms was also disussed on the basis of personal experience.
