- W2043978330 abstract "Las fístulas aortoentéricas son una complicación infrecuente de los aneurismas de aorta abdominal. Se dividen en 2 tipos: primarias, debidas a la comunicación espontánea de la luz de un aneurisma aórtico y un asa intestinal, principalmente el duodeno, y secundarias, más frecuentes que las anteriores, que ocurren en pacientes intervenidos de reparación quirúrgica de aneurismas con implantación de prótesis. El signo clínico de presentación más frecuente de las fistulas aortoentéricas es una hemorragia digestiva alta. La sospecha clínica supone un pilar fundamental en la aproximación diagnóstica de las fístulas aortoentéricas, y la endoscopia y la tomografía computarizada son las técnicas más usadas para su diagnóstico, aunque no es infrecuente que estas técnicas sean negativas y se realice el diagnóstico en la cirugía. Presentamos 3 casos de fístulas aortoentéricas (una de ellas primaria) con diferentes patrones de hemorragia digestive alta, en los que el contexto clínico y los hallazgos de tomografía computarizada helicoidal permitieron su diagnóstico preoperatorio; discutimos el papel de esta técnica para el diagnóstico, y describimos los diferentes hallazgos que permiten sospechar o confirmar una fístula aortoentérica. Aortoenteric fistula (AEF) is an uncommon complication of abdominal aorta aneurysms. They are divided into two types: primary AEF due to a spontaneous communication of the lumen of an aortic aneurysm and an intestinal loop, usually the duodenum, and secondary AEF, which are more common and occur in patients who have undergone surgical repair of aneurysms with prosthetic implants. The most frequent presenting sign of AEF is upper gastrointestinal bleeding. Clinical suspicion is essential in the diagnostic approach to AEF and the most commonly used techniques for its diagnosis are endoscopy and computed tomography (CT). However, it is not unusual for the results of these techniques to be negative and for the diagnosis to be made at surgery. We present three cases of AEF (one primary) with distinct patterns of upper gastrointestinal bleeding, in which preoperative diagnosis was allowed by clinical and helical CT findings. We discuss the role of this technique in the diagnosis of this entity and describe the findings that allow AEF to be suspected or confirmed." @default.
