Images in clinical medicine: common iliac artery aneurysm with arteriovenous fistula

Abstract

A 75-year-old male was admitted with sudden onset of unilateral left lower limb swelling and pain. He was a hypertensive on treatment for the past 10 years and a chronic smoker. On examination, the patient’s blood pressure was 220/130 mm Hg and he had palpable abdominal pulsations. A bruit was audible over the patient’s lower abdomen. An ultrasound showed a retroperitoneal cystic mass and CT scan confirmed the presence of large aneurysm involving the left common iliac artery which was compressing upon the ipsilateral common iliac vein . A fistulous communication was found between the left common iliac artery and the vein with early contrast opacification of the common iliac vein and the inferior vena cava in the arterial phase .
