[Arterial hypertension of renovascular origin]

We present 5 renal artery stenosis in 3 patients, 2 of them affected of neurofibromatosis. Percutaneous transluminal angioplasty was successful in one left renal artery. The operation was carried out in 4 renal arteries, 2 aortorenal reimplantations, 1 splenorenal bypass and 1 patch angioplasty using saphenous vein were performed. At this time 2 children are normotensive and do not require medication, and 1 child is normotensive and is receiving antihypertensive medication at a smaller doses that those necessary before operation. The good permeability of anastomosis was verified in all cases.
