Acquired intraabdominal arteriovenous fistula (AVF) is a rare disorder where the communication most commonly occurs between the abdominal aorta and inferior vena cava. Ilioiliac AVF has been reported previously, but is exceedingly rare. We present a case of acquired arteriovenous fistula of the right common iliac artery and left common iliac vein with extensive collateralization (ilioiliac AVF) in a 36-year-old female who presented with symptoms of high output congestive heart failure 18 years after sustaining an abdominal gunshot wound.
