Discussion

Inferior Mesenteric Vein drains the rectum, and sigmoid and descending parts of the colon. It begins as the superior rectal vein, from the rectal plexus, through which it connects with middle and inferior rectal veins. The superior rectal vein leaves the pelvis and crosses the left common iliac vessels medial to the left ureter with the superior rectal artery, continuing up as the inferior mesenteric vein. This is left of its artery, ascending behind the peritoneum anterior to the left psoas major; it may cross the testicular or ovarian vessels or be medial to them and then passes above, or behind, the duodenojejunal flexure, opening into the splenic vein posterior to the body of the pancreas; sometimes it ends at the union of the splenic and superior mesenteric veins.

Explanation

If a duodenal or paraduodenal fossa exists, the vein is usually in its anterior wall.

Comments

Its tributaries are sigmoid veins from the sigmoid colon and the left colic vein from the descending colon and the left colic flexure.
