Emergency Endovascular Aneurysm Repair Coupled with Staged Omentopexy for Primary Aorto-Duodenal Fistula.

A primary aorto-duodenal fistula (ADF), a rare, spontaneous development of a communication between the aorta and duodenum, is a disastrous complication of an abdominal aortic aneurysm. A 73-year-old patient with primary ADF underwent emergent endovascular aneurysm repair (EVAR), followed by staged omentopexy, without removing a stent graft (SG). The patient received long-term treatment with antibiotics, and there has been no evidence of infection during a follow-up period of three years. Emergency EVAR coupled with omentopexy, may be a treatment option for primary ADF, even when it means leaving the SG in a potentially infectious site.
