Successful percutaneous transluminal angioplasty for treatment of renovascular hypertension in a 15-month-old child.
In young children with renal artery stenosis the applicability of percutaneous transluminal angioplasty is limited by the small vessel size. We report our experience in a 15-month-old girl with severe hypertension, who underwent successful balloon dilatation of a tight renal artery stenosis caused by fibromuscular dysplasia. The procedure was performed using the guided co-axial balloon catheter technique with a 6 F right coronary Judkins catheter, a 0.014" guidewire and a 2 mm coronary artery balloon dilatation catheter. Antihypertensive medication was discontinued 6 weeks after the procedure. During a follow up period of 11 months, Doppler sonography revealed no evidence of recurrent renal artery stenosis.


CONCLUSIONS
Percutaneous transluminal angioplasty of renal artery stenosis can be performed safely in young children using equipment originally designed for treatment of coronary artery stenosis in adults.
