Successful Emergency Operation for a Graft-Enteric Fistula with Massive Melena and Sepsis: A Case Report

Abstract

A 44-year-old male, with past history of mitral valve re-replacement, tricuspid annuloplasty and re-replacement of aorto-biiliac prosthetic graft 4 years previously, was admitted to Asahi General Hospital because of massive melena, sepsis and shock. Angiography revealed a false aneurysm at the site of the anastomosis between the graft and the right external iliac artery. He was diagnosed as having graft-enteric fistula, and the emergency operation, including partial resection of the graft, excision of the false aneurysm and extraanatomic bypass, was performed successfully. Pathogenesis, diagnosis and treatment of graft-enteric fistula are discussed.
