OBJECTIVE Presentations of a spontaneous ilio-iliac arteriovenous fistula are considered a rare occurrence and warrant urgent intervention. They are usually a result following trauma, previous surgery or uncommonly from a ruptured aneurysm. METHOD We describe a case of a patient presenting with general malaise who examined to have a pulsatile abdominal mass with an associated bruit. He was found to have an ilio-iliac arteriovenous fistula secondary to a ruptured iliac aneurysm that was treated successfully with open surgical repair. RESULT The patient was brought forward for open surgical repair due to haemodynamic instability as well as likely predicted difficulties with endovascular repair. Intra-operatively, his sigmoid colon was adherent to the aneurysm prompting the need for a Hartmann's procedure to allow for better visualisation of the aneurysm. A combination of external digital compression and Prolene suture was used to close the arteriovenous fistula. CONCLUSION Open surgical repair of an ilio-iliac arteriovenous fistula secondary to a ruptured iliac aneurysm appears to be safe and feasible approach. The advancement of medical technology does open up the possibility of an endovascular approach; however, in a small subset of patients, open repair would appear to be better.
