Hybrid repair of internal iliac arteriovenous aneurysm fistula presenting with lower limb pain: A case report

Iliac arteriovenous fistula is a rare vascular disease defined as the formation of an abnormal channel between the iliac artery and vein. The high mortality rate associated with an iliac arteriovenous fistula resulting from a ruptured iliac arterial aneurysm necessitates early diagnosis and timely, appropriate management. We report a case of an 86-year-old man presenting with lower limb pain and edema. Computed tomography angiography demonstrated a large internal iliac artery aneurysm with a fistula to the adjacent vein. Symptoms resolved once a hybrid repair was performed.
