Operative Anatomy

The arterial supply of the temporal lobe is from both the anterior circulation, via the inferior trunk of the middle cerebral artery (MCA) branches coursing through the Sylvian fissure, and posterior circulation, via the posterior cerebral artery (PCA) branches coursing through the crural and ambient cisterns.

As a general principle, the Sylvian and lateral aspects of the temporal lobe are fed mostly by the MCA branches; the inferior or basal aspects are supplied mostly by the PCA branches. Anteromedial temporal lobe structures, including the amygdala and hippocampus, are supplied by the anterior choroidal artery, the anterior thalamoperforatoring branches of the posterior communicating artery (PCoA) and the PCA perf...
