Bifurcated Endograft Repair of Ilio-iliac Arteriovenous Fistula Secondary to Lumbar Diskectomy

Ilio-iliac arteriovenous (AV) fistula is a rare complication after lumbar diskectomy. Endovascular repair of such fistulas is a growing trend in vascular surgery. This is a case report of an endovascular exclusion of an ilio-iliac AV fistula in a 51-year-old male. This man presented with high-output congestive heart failure and ascites. The AV fistula was discovered 17 years after a lumbar diskectomy. Computed topography (CT) revealed a right common iliac artery pseudoaneurysm connecting to the left common iliac vein. The fistula was repaired using a bifurcated Gore Excluder endograft. There were follow-up CT scans at 6 and 10 months confirming exclusion of the AV fistula. Endovascular AV fistula repair offers a safe, effective method for managing ilio-iliac AV fistulas.
