Pancreas blood supply anatomy - Venous drainage

The pancreas's venous drainage is a complex network that closely parallels the arterial supply, ultimately draining into the portal venous system. This intricate venous anatomy is crucial for maintaining pancreatic circulation and has significant clinical implications, especially in pancreatic surgery and the management of pancreatic tumors. The head of the pancreas is primarily drained by the pancreaticoduodenal veins, which correspond to the pancreaticoduodenal arteries. The superior pancreaticoduodenal veins drain into the portal vein, while the inferior pancreaticoduodenal veins drain into the superior mesenteric vein. These venous channels establish an essential connection between the portal and systemic venous circulation, playing a pivotal role in the drainage of the pancreatic head and duodenum. One of the key venous structures in the pancreas is the gastrocolic trunk of Henle, a venous confluence located near the lower border of the pancreatic neck. This important vascular structure collects blood from the right gastroepiploic vein, the anterior superior pancreaticoduodenal vein, and sometimes additional tributaries before draining into the superior mesenteric vein. Understanding the anatomy of the gastrocolic trunk is crucial for pancreaticoduodenectomy (Whipple procedure), as inadvertent injury to this structure can lead to significant intraoperative bleeding and venous congestion. Another vital venous component is the first jejunal vein, which emerges from the jejunum and drains into the superior mesenteric vein. Its close anatomical relationship with the pancreatic head and uncinate process makes it an important landmark during pancreatic surgery. Surgeons must carefully identify and preserve this vein when mobilizing the pancreas to prevent excessive blood loss and complications related to venous congestion. The middle colic vein, which drains the transverse colon, also has significant relevance to pancreatic surgery. It typically empties into the superior mesenteric vein, but variations exist, including drainage into the gastrocolic trunk. Its proximity to the pancreatic neck and uncinate process means that careful dissection is required during pancreatic resections to avoid vascular injury. The body and tail of the pancreas drain primarily via the splenic vein, which receives multiple pancreatic tributaries before joining the superior mesenteric vein to form the portal vein. These venous connections are vital in maintaining effective portal circulation and ensuring adequate blood flow to the liver. In this detailed video, Dr. Gunjan Desai, DNB Teaching Faculty for gastrointestinal, liver, and pancreatic surgery at Lilavati Hospital, Mumbai, provides an in-depth discussion on the venous drainage of the pancreas. The video highlights the anatomy and surgical relevance of key venous structures, including the gastrocolic trunk of Henle, the first jejunal vein, and the middle colic vein.
