Spontaneous Dissection of the Iliac Artery in a Patient With Fibromuscular Dysplasia

A 49-year-old man was referred to our hospital at 10 days after the onset of sudden intermittent claudication of the right lower limb and with right lower abdominal pain. Diagnosis by computed tomography scan and pelvic angiography was dissection from the common iliac artery to peripheral external iliac artery with thrombosed false lumen. Replacement of the common and external iliac artery was performed using a 10-mm Dacron prosthesis. A pathological examination of the right common iliac artery revealed an arterial disorder caused by fibromuscular dysplasia.
