We present a case of successful transluminal balloon dilatation of renal artery stenosis in a pediatric patient.

A 3-year-old boy was noted on the treatment of otitis media to have a blood pressure of 290/180mmHg. Subsequent repeat measurements in all extremities ranged from 200 to 290mmHg systolic with diastolic values from 100 to 180mmHg. Past history was negative except for MCLS, for which he underwent coronary arteriography which revealed no significant organic stenosis. There was no history of hypertension in the immediate family.

Laboratory studies including urinalysis, blood count, blood chemistry, 24-houre VMA and catecholamines were all within normal limite except for plasma renin activity and serum aldosterone levels. Renogram revealed malfunction of right kidney with slight degree.

Renal arteriogaphy showed 80% stenosis of right renal ventral artery and we performed Percutaneous Trans-luminal Renal Angioplasty (PTRA) with Judkins tech-nique. A repeat abdominal aortogram following PTRA showed the right renal artery to be of almost normal caliber.

After PTRA, blood pressure, plasma renin activity and angiotensin I level were normalized without me-dicine.
