An acute abdominal syndrome reveals a postoperative ilio-iliac arteriovenous fistula: about one case.

Introduction: Postoperative ilio-iliac arteriovenous fistula is an unusual but known complication after lumbar surgery.

Case Report: We report the case of a 74-year-old patient consulted at the emergency department for intense acute abdominal syndrome revealing a post-operative common ilio-iliac arteriovenous fistula 5 years after a lumbosacral arthrodesis L3-S1. The patient was treated with an endovascular arterial stent-graft with immediate vascular and clinical results.

Conclusion: Arteriovenous fistula is a possible etiology of acute abdominal syndrome in patients with lumbar or abdominopelvic surgery history.
