The Splenic Artery of a Human Male Viewed Posteriorly

Description

Arising from the celiac trunk and coursing leftward along the superior border of the pancreas, the splenic artery is shown from a posterior perspective as a characteristically tortuous vessel approaching the splenic hilum (hilum lienis). The spleen (lien) sits in the left upper quadrant with its smooth capsule (capsula lienis) facing posteriorly, while the pancreatic body and tail lie medial and slightly inferior to the splenic parenchyma, with the tail nearing the hilum. Short gastric branches toward the gastric fundus and terminal hilar branches are implied as the artery divides near the splenic capsule. The splenic vein typically tracks more posterior and inferior to the artery along the pancreas, converging toward the portal venous system. Posterior viewing clarifies the relationship of the splenic artery to the pancreatic tail, a frequent site of iatrogenic injury during distal pancreatectomy and splenectomy. Tortuosity is not just an artistic convention, it affects catheter navigation during angiography and underlies why aneurysms often occur along the distal third of the splenic artery, with pregnancy and portal hypertension among recognized risk associations. Bleeding here can track rapidly into the lesser sac. Orientation to the hilum also supports teaching of segmental splenic vascular anatomy, which matters for partial splenectomy and for controlling hilar bleeding. Useful for upper abdominal anatomy teaching in gross dissection labs, surgical atlases discussing left subcostal and retroperitoneal approaches, and interventional radiology materials on selective splenic artery embolization for blunt splenic trauma or hypersplenism. Also appropriate for gastroenterology and pancreatic surgery publications that need a clear posterior map of splenic artery course relative to the pancreas and duodenum.
