Percutaneous transluminal angioplasty for pediatric renovascular hypertension.

Five children had percutaneous transluminal angioplasty (PTA) for renal artery stenosis, involving the mid- or distal main renal artery or proximal branches in 4 and developing after saphenous vein patch angioplasty in 1. All 5 children became normotensive following the procedure, but one later became hypertensive due to recurrent renal artery stenosis. The authors recommend PTA for treatment of mid- to distal renal artery stenosis in children.
