Variations in the course of the arteria centralis longa of the anterior cerebral artery in man.
The arteria centralis longa (the extracerebral course of the vessel) was studied in 20 human brains (40 hemispheres taken from adults of both sexes). Brain vessels were injected with plastogen G, dissected and etched in soda lye. Arteria centralis longa was present in 36 hemispheres, and orginated from the anterior cerebral artery in the region of the origin of anterior communicating artery in 51% of the cases, from the post-communicating (A-2) segment of the anterior cerebral artery in 44% of the cases, and from the precommunicating (A-1) segment of the anterior cerebral artery in 5% of the cases.
