title: Percutaneous transluminal angioplasty for treatment of renovascular hypertension.
abstract: Four patients with typical renovascular hypertension due to atherosclerotic stenosis (3 patients) and near occlusion (one patient) were treated with percutaneous transluminal angioplasty (PTA). Two patients had malignant hypertension by clinical standards. All had significant reduction in blood pressure following angioplasty, resulting in either a normotensive state, or management with significantly less antihypertensive medication. Patency and normal renin levels were achieved within two months in 2 patients. Clinical follow-up documented continued reduction in blood pressure. Advantages of the procedure include local anesthesia, relatively little discomfort, repeatability, and the fact that surgery is not precluded if angioplasty is unsuccessful.
