Inferior Pancreatic Vein, Posterior View

Description

Arising along the inferior border of the pancreas, the inferior pancreatic vein is traced posteriorly as it courses toward the splenic vein, which runs horizontally along the posterior surface of the gland on its way to the portal venous system. From this posterior perspective, the spleen sits in the left upper quadrant lateral to the pancreatic tail, while the pancreatic body and tail lie medial to the splenic hilum and anterior to the retroperitoneal vascular plane. A segment of proximal small intestine, consistent with the duodenum, appears to the right of the pancreatic head, framing the gland’s rightward extent. Posterior venous anatomy of the pancreas matters because these small tributaries are the ones you meet when mobilizing the pancreas off the splenic vein during distal pancreatectomy or splenectomy, and they are easy to avulse if you underestimate how short they can be. Bleeding here is venous, brisk, and often obscures the correct plane between pancreatic parenchyma and the splenic vein. This relationship also helps explain patterns of left-sided portal hypertension when splenic vein thrombosis complicates pancreatitis or a pancreatic tail mass. Use this plate for surgical anatomy teaching (upper GI and hepatopancreatobiliary modules), for atlas figures that need accurate portal venous tributaries, or for illustrating operative reports and patient education materials on distal pancreatectomy and splenic vessel preservation techniques.
