Lasting Antihypertensive Effect of Percutaneous Transluminal Angioplasty of Renal Artery Stenoses in a Child

Am J Dis Child. 1983;137(6):600-601. doi:10.1001/archpedi.1983.02140320076019

While percutaneous transluminal angioplasty (PTA) of renal artery stenoses was introduced five years ago in adults1 as a therapeutic modality for renal vascular hypertension with lasting success,2 to our knowledge, the application of PTA in children with this diagnosis has not been reported. We report the long-term effects of PTA of two renal artery stenoses in a 5-year-old boy with renovascular hypertension.

Report of a Case.—A 4½-year-old boy (weight, 17.5 kg; height, 105.5 cm) had a history of dizzy spells, headache, and three seizures during the previous month. Blood pressure was 180/130 mm Hg; urinalysis findings were normal. Stenoses in the left renal artery and in a right renal polar branch were shown angiographically (Fig 1, left), and renovascular hypertension was diagnosed after exclusion of other causes. The systemic renin activity was elevated (40 ng/mL/hr). The boy underwent bilateral PTA on Oct 23, 1980, while he was
