The splenic vein is formed from small venules that leave the spleen. It travels above the pancreas, alongside the splenic artery.It collects branches from the stomach and pancreas, and most notably from the large intestine (also drained by the superior mesenteric vein) via the inferior mesenteric vein, which drains in the splenic vein shortly before the origin of the hepatic portal vein.
In medicine, a distal splenorenal shunt procedure (DSRS), also splenorenal shunt procedure and Warren shunt, [1] is a surgical procedure in which the distal splenic vein (a part of the portal venous system) is attached to the left renal vein (a part of the systemic venous system).
Splenic vein; Superior mesenteric vein; Inferior mesenteric vein; The superior mesenteric vein and the splenic vein come together to form the actual hepatic portal vein. The inferior mesenteric vein connects in the majority of people on the splenic vein, but in some people, it is known to connect on the portal vein or the superior mesenteric vein.
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 .
The smaller veins unite to form larger veins that do not accompany the arteries, but soon enter the trabecular sheaths of the capsule, and by their junction form six or more branches, which emerge from the splenic hilum, and, uniting, constitute the splenic vein, the largest radicle of the portal vein.
The fibroelastic coat of the spleen invests the organ, and at the hilum is reflected inward upon the vessels in the form of sheaths. From these sheaths, as well as from the inner surface of the fibroelastic coat, numerous small fibrous bands, the trabeculae of the spleen (or splenic trabeculae), emerge from all directions; these uniting, constitute the frame-work of the spleen.
The splenic vein sits over the pancreas anatomically. Inflammation or cancers of the pancreas may result in a blood clot forming in the splenic vein. As the short gastric veins of the fundus of the stomach drain into the splenic vein, thrombosis of the splenic vein will result in increased pressure and engorgement of the short veins, leading to ...
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).
