Intrarenal arterial stenosis. Saralasin acetate infusion test as an aid to diagnosis.

This report documents a case of hypertension caused by an intrarenal arterial stenosis in a ten-year-old girl. The renovascular origin of her hypertension was suggested by a positive saralasin acetate infusion test, and the lesion was identified by use of the subtraction technique in renal arteriography. Partial nephrectomy resulted in resolution of the patient's hypertension with good function in the remaining portion of the kidney.
