[Percutaneous transluminal angioplasty in renovascular hypertension].

Five children with renovascular hypertension were treated with percutaneous transluminal angioplasty, and followed for 12 to 32 months. Blood pressure fell to normal in four patients and improved in one. Angiographic and endocrinological improvements were associated with a fall in blood pressure and no complications were observed. Angioplasty is considered a safe, effective treatment for children with renovascular hypertension.
