title: Failure and success of percutaneous angioplasty in a hypertensive child with bilateral renal artery stenosis.
abstract: We describe the clinical course of a 5-year-old girl with severe arterial hypertension that was uncontrollable with antihypertensive medication. Renal angiography revealed bilateral renal artery stenoses. Because percutaneous transluminal renal angioplasty (PTRA) failed to dilate the stenotic lesions, a renal artery bypass grafting in both renal arteries was performed. The patient remained normotensive for 7 months, and after that the arterial pressure increased again. Digital subtraction angiography demonstrated stenosis at the peripheral and central anastomosis of the vein graft that was used for revascularization of the left kidney. PTRA was decided on and successful patency was achieved. The patient has now been normotensive for a period of 5 years.
