Catheter atherectomy of intimal fibroplasia of the common iliac artery.

An 18-year-old woman presented with renovascular hypertension and left lower extremity claudication. Aorto-iliac angiography showed stenotic lesions in the left renal artery and the left common iliac artery. For uncontrolled hypertension, nephrectomy was performed and histopathology of the renal artery showed intimal fibroplasia, an uncommon type of fibromuscular dysplasia. The left common iliac artery lesions were treated with directional atherectomy, which produced excellent immediate angiographic and symptomatic improvement.
