The superior mesenteric vein is considered to develop from this tissue cleft. It arises anterior to lower border of vertebra L1 in an adult. Human embryogenesis is a very delicate process during which the development of the SMV and rotation of the intestine starts approximately at the same time [1, 3].The superior mesenteric vein develops secondarily to the regression of the left vitelline vein in the midgut mesentery [].After formation it runs slightly anterior and to the right of the superior mesenteric artery most of the time. This vein is located in the abdominal cavity next to the superior mesenteric artery. Rather than the vitelline vein being the primitive basis for the superior mesenteric vein, this study suggests the only contributions of the vitelline vein is the portion of the portal vein at the conflux of the superior mesenteric and splenic veins. Portal vein thrombosis (PVT) can be seen in 5-10% of patients with portal hypertension with increased incidence with more severe liver disease. superior mesenteric vein and splenic vein. 1).2 There is no specifically distinct artery to splenic flexure, The inferior mesenteric vein usually enters the splenic adjacent to the confluence, but it may also enter the SMV either at or just caudal to the confluence. vein empties into the splenic vein and drains the.
