- The aneurysms located on vertebra-basilar artery junction and mid-basilar
artery are not common. These aneurysms may be surgically clipped through a variety
of approaches. The suboccipital approach has potential morbidities due to retraction
of cerebellum and brain stem. The supratentorial approach may have retraction
damage to the temporal lobe and the vein of Labbe.
Resection of petrous bone in combined approach of supratentorial and infratentorial
route has some advantages. There is minimal retraction of cerebellum, brain stem and
temporal lobe, preservation of the vein of Labbe and shortening of the operative distance.
Thus the petrosal approach may be helpful for the surgery of aneurysms arising
around vertebro-basilar artery junction and mid-basilar artery. We have clipped an aneurysm
on the vertebro-basilar artery junction and mid-basilar artery with petrosal approach
and discuss its usefulness for the approach to aneurysms on vertebro-basilar artery
junction and mid-basilar artery.
