Left external iliac artery dissection and bilateral renal artery aneurysms secondary to fibromuscular dysplasia: a case report.

Abstract

A case of acute lower limb ischaemia due to spontaneous dissection of the left external iliac artery and coincidental bilateral renal artery aneurysms is reported. Histopathological examination of the resected iliac artery showed features of fibromuscular dysplasia. Dissection of the external iliac artery without involvement of the aorta is extremely rare with only two previously reported cases. The aetiology and management of fibromuscular dysplasia is discussed.
