[Neck clipping of an aneurysm at the basilar artery-anterior inferior cerebellar artery via presigmoid-transmastoideal approach].
A 51-year-old man presented severe disturbance of consciousness and massive subarachnoid hemorrhage. Angiography disclosed an aneurysm at the ventral bifurcation of the basilar and anterior inferior cerebellar arteries. Neck clipping and additional wrapping/coating were performed via the presigmoid-transmastoideal approach with successful result.
