title: [Aorto-intestinal fistulas. 4 case reports].
abstract: Four cases of aorto-enteric fistula are reported. The two primary types occurred after rupture of an aneurysm of the abdominal aorta into the duodenum and as a consequence of tumor infiltration of both the aorta and the intestinal wall in a woman with metastatic ovarian cancer. The two secondary types developed as a late complication of reconstructive surgery of the abdominal aorta. The condition was diagnosed or suspected on the basis of endoscopic findings in two cases. The pathogenetic role of graft infection in the development of secondary aorto-enteric fistula is emphasized. The generally poor prognosis can be considerably improved if prompt resection of the graft is combined with axillo-bifemoral anastomosis.
