Transsylvian Perspective of ICA Bifurcation

Surgical Correlation


Transsylvian Perspective of ICA Bifurcation. The internal carotid artery can be observed coursing superiorly and bifurcating into the anterior cerebral artery (A1) and middle cerebral artery (M1). The lenticulostriate arteries are demonstrated by retraction of the M2 branches along with the temporal lobe. The recurrent artery of Heubner can be seen coursing parallel to the frontal lobe from its origin along the proximal A2 segment. The temporopolar artery can be observed originating from the distal M1 segment to perfuse the anterior temporal lobe. The anterior temporal artery is demonstrated coursing along the temporal lobe to perfuse the anterior third of the superior, middle, and inferior temporal gyri. The anterior temporal artery has its origin from the distal M1 segment, which is masked by the M2 branch in this image. (Image courtesy of PA Rubino)
