Aorto-enteric fistula: CT findings

Abstract: The objective of this pictorial essay is to present the different CT findings encountered in patients with aorto-enteric fistulas (AEFs). An AEF is a rare and sometimes disastrous occurrence, responsible for intermittent or massive gastrointestinal hemorrhage and hematemesis. CT provides fast and effective evaluation in hemodynamically stable patients suspected of having an AEF.

“…CT and three-dimensional CT have been considered as valuable assets in the diagnosis of complex vascular pathoanatomy. [12][13][14] Three-dimensional CT is a safe, simple, and noninvasive examination method, which has high sensitivity and specificity for the early diagnosis of AEF. Compared with digital subtraction angiography (DSA), reconstruction image of three-dimensional CT can clearly show the extent of aortic disease and the relationship between AEF and the foreign body.…”

“…En cas d'hémorragie d'origine indéterminée, des examens complé-mentaires doivent impérativement être pratiqués à la recherche de fistule, mais la normalité du TDM même injecté n'exclut pas le diagnostic. Ainsi, le diagnostic radiologique ne peut parfois être porté que sur des signes indirects, tels que des signes d'infection, présence ectopique d'air ou encore épaississement des parois digestives en regard [5]. L'infection de prothèse est présente de façon quasi systéma-tique lors de FAE [6,7].…”

“…In case of a negative CT scan, additional studies-including magnetic resonance imaging (MRI), gastroenteric endoscopy, In-labeled white blood AEF aortoenteric fistula cell scanning, red blood cell scintigraphy, positron emission tomography-are alternative diagnostic examinations that can be utilized. The sensitivity of MRI has not been investigated, and its diagnostic value is unclear [8,11]. Sensitivity of upper GI endoscopy has been reported to be 50-55% [7,12], and it is reported to be useful mainly for excluding other causes of bleeding [13,14].…”

“…The CT scan is considered the imaging investigation of choice in suspected aortoenteric fistula [8], even if some authors suggest gastroenteric endoscopy as the initial diagnostic procedure to perform [7].…”
