Transluminal catheter angioplasty of abdominal aorta in Takayasu's arteritis

Nine patients with Takayasu's arteritis and a long stenotic segment of the abdominal aorta were treated by percutaneous transluminal angioplasty (PTA). Intermittent claudication disappeared in six of seven cases, the femoral pulse reappeared in all five; ankle/arm indices increased in seven cases; elevated blood pressure normalized in seven of eight cases. Seven patients were followed for 3 to 28 months. They were all free of symptoms from the lower extremities. In three patients with or without renal artery stenosis and with hypertension, the blood pressure decreased after PTA of the abdominal aorta only. PTA may be a valuable treatment in Takayasu's arteritis and stenosis of the abdominal aorta.
