A RARE REASON FOR GASTROINTESTINAL SYSTEM BLEEDING: AORTOENTERIC FISTULA

Öz

Aorto-enteric fistula is a rare clinical picture with a high incidence of mortality among causes of gastrointestinal bleeding. Aorto-enteric fistulas, seen as primary or secondary, develop most frequently after aortic graft operation. Anamnesis plays a very important role in the diagnosis of aorto-enteric fistula since it is at first an unsuspected cause of gastrointestinal bleeding.

In this article, we report a case of a 75-year-old male patient with gastrointestinal bleeding in whom the bleeding focus could not be determined despite repeated endoscopies. The diagnosis of aortic dissection and aorto-enteric fistula was achieved following CT angiography and aortic graft sheath CT.

Gastrointestinal Sistem Kanamalarının Nadir Bir Nedeni: Aorto-enterik Fistül

Öz

Aorto-enterik fistül, gastrointestinal sistem kanama nedenleri arasında nadir görülen, mortalitesi yüksek olan klinik bir tablodur. Primer veya sekonder olarak görülen aorto-enterik fistüller en sık aort grefti operasyonu sonrasında gelişmektedir. Gastrointestinal kanamalı hastanın tanısında ilk olarak akla gelmeyen bu tablonun tanısında anamnez çok önemli bir rol oynamaktadır.

Bu makalede tekrarlanan endoskopilere rağmen kanama odağı belirlenemeyen, aort grefti öykülü, batın CT-anjiografi ve operasyon sonrasında aort disseksiyonu ve aorto-enterik fistül tanısı saptanan gastrointestinal kanamalı 75 yaşında bir erkek hasta sunulmaktadır.
