“…IMV begins as the superior rectal vein at about the mid-point of the anal canal, then passes along the inferior mesenteric artery to end in the SV. It receives blood from the superior rectal veins, the sigmoid veins and the left colic vein (Snell, 2012), (Kaur et al, 2017) In this report, we present a case of an unusual giant IMV with an anomalous insertion in the presence of cirrhosis observed during routine dissections at the Department of Anatomy, University of Peradeniya.…”

The inferior mesenteric vein is one of the tributaries of the portal vein which receives blood from the large intestine, sigmoid colon and the rectum. It usually connects with the splenic vein before draining into the portal vein. It may however show variations such as joining the superior mesenteric vein directly or to the confluence of the superior mesenteric vein and splenic vein. Varices of the inferior mesenteric vein can be seen in the presence of portal hypertension due to various reasons and this can be isolated or in association with other portosystemic collaterals.We report a case of a giant isolated inferior mesenteric vein with an anomalous insertion. The inferior mesenteric vein was seen to be connected to the superior mesenteric vein before draining into the portal vein. Further, on the distal end it was seen to be connected to the left renal vein, which in turn had dilated and enlarged. The left testicular vein was observed draining in to the inferior mesenteric vein but was not enlarged. The superior mesenteric vein, splenic vein and portal vein were not enlarged or varicosed even though the liver showed features of cirrhosis with no obvious signs of splenic enlargement. This report contributes to enhance the knowledge on a rare anatomical connection between portal system and the systemic circulation and will be important to surgeons operating in this area.

“…Anatomical references related to PV structures primarily focus on the SMV and SpV, offering limited information about the IMV, except for its common drainage into the SpV [1]. Nevertheless, recent studies have revealed that the IMV can also merge and discharge into the SMV, the junction between the SpV and SMV, or other mesenteric venous drainage regions [2,3].…”

Background/Aim: The inferior mesenteric vein (IMV) plays a crucial role in the venous system as it joins the superior mesenteric vein (SMV) and splenic vein to form the portal vein. The widespread adoption of multidetector computed tomography (MDCT) has greatly enhanced our ability to assess abdominal vascular structures. This study aimed to investigate the IMV drainage patterns in a Turkish population using MDCT. Methods: This descriptive, single-center, retrospective study included patients who had undergone abdominal computed tomography (CT) in the portal phase at our hospital for various clinical indications. Excluded from the study were patients who did not undergo imaging in the portal venous phase, those with incomplete evaluation of all IMV segments, and individuals who had undergone pancreaticoduodenal or intestinal surgery for any reason. We retrospectively analyzed a total of 877 contrast-enhanced MDCT examinations performed at our hospital between March 2022 and March 2023. Patients were classified based on their IMV drainage patterns into the following categories: type 1 (drainage into the splenic vein), type 2 (drainage into the SMV), type 3 (drainage at the junction level), type 4 (drainage into the branches of the SMV), and type 5 (patients in whom IMV assessment was not possible). Results: The mean age of the patients was 48.7 years (range: 24–92 years), with 449 (51.2%) being male and 428 (48.8%) female. The distribution of patients according to IMV drainage patterns was as follows: type 1, n=379 (43.2%); type 2, n=398 (45.4%); type 3, n=71 (8.1%); type 4, n=15 (1.7%); and type 5, n=14 (1.6%). Conclusion: Our study findings indicate that in the Turkish population, the IMV predominantly drains into the SMV before joining the splenic vein. This disparity from certain studies in the literature underscores the variability in IMV drainage patterns, emphasizing the importance of individualized patient evaluation in this regard.
