Rectal vein: The superior rectal vein, or superior hemorrhoidal vein, connects veins surrounding the rectum to the inferior mesenteric vein. The rectal vein is the main link between blood exiting all veins around the rectum. If the vein's tributaries swell, they will push into the rectum becoming internal hemorrhoids. The risk factors include: constipation, pregnancy, liver disease and diet lacking fiber.
