ABSTRACT

The pterional(Transsylvian) and subtemporal approaches are main surgical route for direct clipping of basilar bifurcation and basilar-superior cerebellar artery aneurysms. In general , the pterional approach has the advantage for high placed aneurysm and the subtemporal approach has the advantage for low placed and posterior directed aneurysm of basilar bifurcation. The authors has been performed surgery for 5 cases of basilar bifurcation and basilar-superior cerebellar artery aneurysms through subtemporal route during 1.5 years with good results in 3 cases, fair result in 1 case, and death in 1 case. We described about this 5 cases detaily and discussed the subtemporal approach for these lesions.
