Background: Despite ongoing improvements in endovascular techniques, open surgical management of basilar apex aneurysms is occasionally necessary.[
Case Description: A 48-year-old woman presented with a Hunt and Hess 1 and Fisher Grade 3 subarachnoid hemorrhage from a small and broad-necked basilar apex aneurysm that was not amenable to endovascular management. An unruptured left A1-A2 anterior cerebral artery aneurysm was also noted on vascular imaging. The patient underwent a combined right subtemporal and pterional approach for sequential clipping of the basilar and anterior communicating artery aneurysms. The third nerve, running between the posterior cerebral artery and the superior cerebellar artery, guided dissection to the basilar artery in the subtemporal approach. A temporary clip was placed on a vessel-free zone of the basilar trunk during dissection of perforators off the posterior aspect of the aneurysm dome. A fenestrated clip around the right P1 segment was used to ensure complete occlusion of the aneurysm. Indocyanine green angiography was used to confirm successful clipping and patency of parent and perforating vessels. The unruptured A1-A2 aneurysm was clipped without difficulty from the pterional trajectory. The patient had an uneventful postoperative recovery with the exception of transient right third nerve palsy.
Conclusion: As highlighted by this case, maintenance of open surgical skills for the treatment of complex aneurysms unamenable to endovascular therapies is critical.
