Transfalcine Approach to a Callosomarginal Artery Aneurysm

Abstract

Abstract We describe a transfalcine approach to clipping and subsequently excising an expanding mycotic callosomarginal aneurysm. The patient had a devastating dominant (left) hemispheric spontaneous intracranial hemorrhage and was neurologically improving at the time of surgery nearly 2 months later. To avoid retracting the left hemisphere, we approached this left callosomarginal aneurysm from the nondominant side through the falx. The approach was straightforward, and the result was satisfactory. (Neurosurgery 29:140-143, 1991)
