Relative positions of the arteries and veins on the dorsolateral surface of the human cerebrum.
We investigated whether arteries pass superficial to veins or whether veins pass superficial to arteries at artery-vein crossings on the anterior, dorsolateral, and posterior surfaces of the human cerebrum. We examined a total of 2,266 artery-vein crossings on 40 sides of 20 cadavers. At 2,059 crossings (91%), the vein passed superficial to the artery. Thus, vein (V), artery (A), and nerve (N), if we regard the cerebrum as nerve, were generally arranged in the order VAN from the superficial to the deep layers. This concept is important for a positional understanding of blood vessels on the cerebrum and it is useful for the understanding of fluid-drainage pathways from the cerebral cortex in various pathological conditions.
