“…2,4 Anomalous formations of the PV previously reported include: preduodenal PV with several accessory portal branches flowing directly in to hepatic segments; 13 multiple SMVs joining with the SV to form the PV; 14 multiple jejunal veins, SMV and SV all joining together to form the PV; 15 preduodenal SMV; 16 and the left gastric vein joining the SMV before it joins the SV to form the PV. 17 All this variability in the formation of the PV should be borne in mind whenever performing intra-abdominal surgeries or interpreting radiological images of the abdomen.…”

Even though the PV is described to originate posterior to the neck of the pancreas, 1 pre pancreatic origins have been described. 10 Furthermore, there is barely scientific literature detailing the location of the PV relative to the neck of the pancreas. The aim of this study therefore was to describe variations in the formation of the PV in a Kenyan population. Methods The present study was carried out during routine dissection in the Department of Human Anatomy, University of Nairobi. A total of 42 adult cadavers (27 male and 15 female) were included in this study. Cadavers that had features of previous abdominal surgeries or trauma were excluded from the study. After a midline abdominal incision to open the abdomen was made, the SMV, IMV and SV were identified and followed up to the point of PV was formation. Photographs of the variations noted were taken.

“…In a study conducted by Pavlos et al 4 , 5.3% of cases did not have a common trunk of the superior mesenteric vein with both the ileal and jejunal veins draining together into the splenoportal confluence. Gorantla et al 8 reported a case where the portal vein was formed by the union of the splenic vein, superior mesenteric vein and inferior mesenteric vein. To the best of our knowledge, there have been no studies in the past that exhibit such a type of anatomical variation where the jejunal veins, superior mesenteric vein and splenic vein are joined to form the portal vein.…”

IntroductionKnowledge of variations regarding the formation, termination and tributaries of the portal vein, superior mesenteric vein and splenic vein are very useful and of utmost importance for surgeons performing surgeries of the pancreas and duodenum. Normally, the jejunal veins are the tributaries of the superior mesenteric vein. We report here, a very unusual case where two proximal jejunal veins drained into the splenic vein instead of the superior mesenteric vein. Case reportDuring the dissection classes for undergraduate medical students, we noted variations in the termination of the upper jejunal veins in an adult male cadaver who was approximately 65 years old. We found that the union of three veins formed the portal vein: the splenic vein, jejunal veins and the superior mesenteric vein. ConclusionFamiliarity with such anatomical variation provides useful information for surgeons performing abdominal surgical procedures.

“…[7] Inferior mesenteric vein joining superior mesenteric vein is described by anatomists. [78] Giant inferior mesenteric vein is described secondary to arteriovenous communications,[9] secondary to portal hypertension,[35] but in both of them they had varices around superior mesenteric vein axis also.…”

Extrahepatic portal hypertension is not an uncommon disease in childhood, but isolated inferior mesenteric portal varices and lower gastrointestinal (GI) bleed have not been reported till date. A 4-year-old girl presented with lower GI bleed. Surgical exploration revealed extrahepatic portal vein obstruction with giant inferior mesenteric vein and colonic varices. Inferior mesenteric vein was joining the superior mesenteric vein. The child was treated successfully with inferior mesenteric – inferior vena caval anastomosis. The child was relieved of GI bleed during the follow-up.
