They run lateralward on the pelvic surface of the levator ani to end in the internal iliac vein. where does the portal vein drain into? The superior and inferior mesenteric veins join the splenic vein behind the pancreas to form the portal vein which carries blood to the liver, which in turn is drained by the hepatic veins which pass into the IVC. Also, where does the inferior rectal vein drain? Inferior rectal veins. The lower part of the external hemorrhoidal plexus is drained by the inferior rectal veins (or inferior hemorrhoidal veins) into the internal pudendal vein.What is venous plexus?A venous plexus is a complex set of interconnected blood vessels.
