Spontaneous ilio-iliac arteriovenous fistula: A rare complication of aorto-iliac aneurysm

Fatima Zohra Benbrahim et al. Radiol Case Rep. .

Abstract

Ilio-iliac arteriovenous fistula is an unusual complication of aorto-iliac aneurysms that can occur spontaneously, traumatically or iatrogenically. The typical clinical presentation includes the characteristic triad of high-output heart failure, a pulsatile abdominal mass with unilateral limb ischemia, or signs of venous congestion. We describe a rare case of spontaneous rupture of an aortoiliac aneurysm into the left common iliac vein of a 65-year-old man, easily diagnosed by angiography. We highlight here the angiographic findings of the ilio-iliac fistula, which was the means of diagnosis in this presentation, especially in patients with atypical clinical features at the outset, and we report the difficulties in choosing the optimal vascular approach.

Keywords: Aneurysm; Arteriovenous fistula; CTA (Angiography); Iliac artery; Iliac vein.
