Iatrogenic arteriovenous fistula (AVF) is an unusual and potentially fatal complication of lumbar spinal surgery. The presentation of these injuries is usually late, with symptoms such as leg swelling or cardiac failure. It is crucial to suspect AVF in the patient which presents to emergency with lumbar spinal surgery history. The diagnosis is often based on imaging studies such as computed tomography (CT) or magnetic resonance (MR) angiography. Surgery was the first choice of treatment, but with recent advances in stent technology endovascular approach has become widely popular. We present two cases of AVF secondary to lumbar spinal surgery, one of them presenting with overt heart failure and the other one with leg swelling.
