title: Portal hypertensive hemorrhage from a left gastroepiploic vein caput medusa in an adhesed umbilical hernia.
abstract: Caput medusa is a frequent incidental finding in patients with portal hypertension that usually represents paraumbilical vein portosystemic collateral vessels draining into body wall systemic veins. A symptomatic caput medusa was seen in a morbidly obese patient after an umbilical hernia repair, which was fed not by the left portal vein but by the left gastroepiploic vein, in a recurrent adhesed umbilical hernia that likely contained herniated omentum. Refractory hemorrhage from this caput medusa was successfully treated by transjugular intrahepatic portosystemic shunt creation and balloon-occluded variceal sclerosis.
