Inferior mesenteric vein - Wikipedia
In human anatomy, the inferior mesenteric vein (IMV) is a blood vessel that drains blood from the large intestine. It usually terminates when reaching the splenic vein, which goes on to form the portal vein with the superior mesenteric vein (SMV).

Sep 11, 2024 · The inferior mesenteric vein (IMV) drains blood from the distal portion of the colon as well as the rectum (i.e. the hindgut). The inferior mesenteric vein drains the mesenteric arcade of the hindgut (comprising of distal transverse, descending, and sigmoid colon).
The Relation between Inferior Mesenteric Vein Ligation and …
IMV is located close to the ligament of Treitz and passes below lower border of the pancreas to join the splenic vein. Moreover, IMV has variable ways of drainage. Usually, it drains into splenic vein, but it may directly join the superior mesenteric vein (SMV) or at the confluence between SMV and splenic vein . 2. Fig. 1.

Regarding the location of IMV drainage, there are several variations: IMV drains into the superior mesenteric vein (SMV), IMV drains into the splenic vein (SPV), IMV drains into the confluence of the SPV and SMV, and IMV drains into the first jejunal vein (J1V).
Inferior mesenteric vein: Anatomy, tributaries, drainage - Kenhub
Oct 30, 2023 · Along its relatively long course across the abdominal cavity, the inferior mesenteric vein receives the sigmoid and left colic veins as tributaries. Thereby, the inferior splenic vein drains blood from the rectum, sigmoid, descending and distal transverse colon.
Inferior mesenteric vein - Structure, Function, Location
Nov 29, 2024 · After collecting blood from its tributaries, the inferior mesenteric vein drains into the splenic vein, which subsequently joins the superior mesenteric vein to form the portal vein. The IMV thus serves as a critical pathway for venous blood to reach the liver.
Familiar-ity with the sonographic anatomy of the IMV minimizes the risk that this vessel will be mistakenly identified as the splenic vein and is useful in the evaluation of patients with portal hypertension. This article presents the sonographic appearance of the IMV in healthy subjects and in patients with portal hypertension.
Inferior Mesenteric Vein: Gray-Scale and Doppler Sonographic
Several findings are helpful to distinguish between the IMV and splenic vein on sonography. In healthy subjects, the diameter of the splenic vein is virtually always greater than or equal to the diameter of the IMV, and the IMV is more intimately related to the left renal vein than is the splenic vein (Fig. 5A, 5B).

Oct 6, 2006 · The IMV inserted into the splenic vein (SV), the portal confluence and the superior mesenteric vein (SMV) in 45%, 18% and 37%, respectively. Among patients with cirrhosis, 12.5% had IMV diameter larger than 5.1 mm, although there was no significant difference between cirrhosis and healthy groups (P> 0.05).
Splenomesenteric vein: formally recognising a clinically relevant ...
Mar 5, 2013 · An overwhelming number of surgical and clinical anatomy textbooks and atlases describe and illustrate two very distinct named veins: the inferior mesenteric vein (IMV) and the splenic vein (SV) [1–3, 5, 6, 8, 9, 11, 12, 14, 16–28]. Apart from an anomaly, the inferior mesenteric joins or merges with the SV on a relatively consistent basis.
