2023年11月3日 · The superior mesenteric vein is a large abdominal vein that is formed by the small terminal veins that drain the ileum, caecum and vermiform appendix. It runs superomedially, traversing the mesentery of the small intestine. Along its course, the vein accompanies the superior mesenteric artery that runs on its left side.

In human anatomy, the superior mesenteric vein (SMV) is a blood vessel that drains blood from the small intestine (jejunum and ileum). Behind the neck of the pancreas, the superior mesenteric vein combines with the splenic vein to form the portal vein that carries blood to the liver.

Your superior mesenteric vein is in your abdominal cavity. This is the large space under your chest and above your pelvis that holds important organs and tissues. Your SMV begins near your belly button, within the part of your mesentery that connects with your small intestine.

2025年1月23日 · The superior mesenteric vein (SMV) is a large vein that drains blood from the small intestine (jejunum and ileum), cecum, ascending colon, and transverse colon. It is a crucial component of the venous system, responsible for transporting nutrient-rich, deoxygenated blood from the digestive organs.[7]

2024年10月3日 · The superior mesenteric vein (SMV) accompanies the superior mesenteric artery (SMA) and drains the midgut to the portal venous system. Mesenteric venous arcades, which accompany the arteries, unite to form the jejunal and ileal veins in the small bowel mesentery and are joined by the tributaries listed below.

2023年8月8日 · The superior mesenteric vein (SMV) is a major venous tributary of the abdominal cavity. Embryologically derived in association with the vitelline vein, the superior mesenteric vein lies lateral to the superior mesenteric artery (SMA) and serves to drain the vast majority of the organs of the abdominal cavity.

A detailed knowledge of the surgical anatomy of tributaries of the superior mesenteric vein, especially proximal jejunal venous anatomy (first jejunal vein and jejunal trunk), is a key...
