Percutaneous transluminal angioplasty of homograft renal artery stenosis in a 10-year-old girl.

Hypertension caused by 90% stenosis of a transplant renal artery was effectively treated by percutaneous transluminal angioplasty of the stenosed artery. Following dilation no pressure gradient existed across the stenosis. Hypertension had developed in a 10-year-old girl with caudal regression syndrome and recurrent pylonephritis five months following homograft transplantation for chronic renal failure. Since percutaneous transluminal angioplasty was performed, the blood pressure has remained within age-related normal limits.
