Subtemporal Transpetrosal Approach for Aneurysms of the Low-Lying Basilar Bifurcation

ABSTRACT

Surgical approaches for aneurysms of the basilar artery trunk are variable and utilized depending on the location of the aneurysms and direction of the fundus of the aneurysms. We operated one patient with low lying basilar bifurcation aneurysms facing toward the brain stem by subtemporal transpetrosal approach with successful clipping of aneurysms. The advantage of this approach to low-lying basilar bifurcation or basilar trunk aneurysms over the pterional, subtemporal(transtentorial), combined supratentorial and infratentorial, transoral, and suboccipital approach are discussed.
