Abstract:
The anterior communicating complex was studied in 25 cadaver specimens obtained at routine autopsy. In 15 specimens (60%), an anomalous anterior communicating artery was found. The most common anomaly identified was a multi-channeled anterior communicating artery. The first channel was always the smallest channel, and all of the perforators arose from this smallest channel 45% of the time. All other anomalous anterior communicating arteries presented with concomitant anomalous perforator anatomy.
