Abstract:
Not infrequently, patients with bilateral cerebral aneurysms are encountered. In such patients, the ability to treat bilateral aneurysms through a unilateral approach spares the patient the risk and inconvenience associated with a separate craniotomy. The contralateral approach for aneurysm repair is technically feasible and safe in appropriately selected patients. Herein, we review our technique for maximizing contralateral exposure and clipping contralateral aneurysms through the four anatomic triangles that serve as corridors in this approach.
