Origin and course
The splenic vein is formed by splenic tributaries emerging at the splenic hilum in the splenorenal ligament at the tip of the tail of pancreas. It runs in the splenorenal ligament in close association with the splenic artery.
- superiorly: splenic artery
- anteriorly: pancreas
- posteriorly: left kidney, left crus of diaphragm (separated by left renal vessels), left psoas muscle, left sympathetic trunk, and the abdominal aorta (separated by superior mesenteric artery and left renal vein)
