Hemorrhoidals interna vena. Mesaraica minor vena. The internal hemorrhoidal vein; the lesser mesaraic vein. It is called haemorrhoidal, from the tumours often found at its"extremity next the anus, and is one of the three great branches of the vena portae ventralis, though sometimes it springs from the splenica: it sends a branch to the duodenum from near its beginning; then it is divided into two branches, one of which ascends, the other descends; the descending branch runs down on the left portion of the colon on its lower incurvations, and on the intestinum rectum to the anus. The haemorrhoidal veins have no valves.
