To the editor,

An aorto-enteric fistula (AEF) is an abnormal communication between the aorta and the gastrointestinal (GI) tract. It can be classified into primary AEF (PAEF) and secondary AEF (SAEF). PAEFs commonly arise from an abdominal aortic aneurysm or inflammatory/infected aorta process (aortitis/sepsis) with an incidence of 0.04–0.07% [1].

SAEFs are an uncommon complication of aortic abdominal reconstruction with an incidence of 0.6–4%. SAEFs can be subcategorised into two types: Type 1, a ‘true’ AEF, which develops between the proximal aortic suture line and GI tract, and Type 2, a para-prosthetic enteric pseudo-fistula with no real communication (i.e. bleeding from an eroded bowel wall) [2]. AEFs typically present with a primary trivial herald bleed that is sometimes followed by a life-threatening gastrointestinal haemorrhage [3]. We present here a rare case of PAEF, diagnosed on CT angiography (CTA) and successfully treated with endovascular aortic repair. We review...
