One Stage Operation of Triple Aneurysms: Case Report

ABSTRACT

In the multiple aneurysm cases of the conservatively treated patients in the cooperative study and in Suzuki's personal series, three aneurysm comprised 15 percent in the multiple aneurysm. Posterior circulation aneurysms is about 15 percent of all intracranial aneurysm. When an aneurysm on the anterior circulation is found, the chance of a secondary aneurysm on the posterior circulation is between 3 and 5 percent. Authors experienced a case of large basilar tip aneurysm projected superiorly and posteriorly accompanied with right middle cerebral artery and right anterior choroidal artery aneurysm. This case was difficult one because of the importance of the perforating vessels in large aneurysm at the basilar fiburcation and the existence of the perforating vessels in large aneurysm at the basilar fiburcation and the existence of another two aneurysms. Through the right pterional approach, three aneurysm were clipped in one stage operation successfully, but the large basilar tip aneurysm was clipped partially because both PCA arose from the aneurysm.
