Fig. 2B. —57-year-old woman with postoperative change to pancreatic head. Drawing shows right-to-left direction of blood flow. Because confluence of superior mesenteric vein with portal vein is obstructed, blood flow of superior mesenteric vein runs into middle colic vein (M), marginal vein along transverse colon, left transverse colic vein, inferior mesenteric vein, then splenic vein. X indicates location of venous obstruction and arrows indicate direction of blood flow. IMV = inferior mesenteric vein, LTCV = left transverse colic vein, MV = marginal vein along transverse colon.
