Transhepatic Portal Venous Angioplasty With Stenting for Bleeding Jejunal Angiodysplasias in a Retrasplant Patient: A Case Report

Abstract A 41-year-old man, who had undergone liver retransplantation, was admitted to our institution complaining of rectorraghia. Gastroscopy and colonoscopy failed to detect the source of bleeding. Computed tomographic angiography detected a stenosis at the portal anastomosis. Capsule endoscopy showed the presence of multiple small bowel angiodysplasias. After a surgical failure, direct portography revealed severe stenosis of the extrahepatic portal vein. Subsequent to percutaneous transhepatic portography, we dilated the stenosis using a balloon catheter and placed an expandable metallic stent, stopping the bleeding without further episodes of gastrointestinal bleeding.
