Seven hypertensive patients underwent percutaneous transluminal angioplasty (PTA) for relief of arterial stenosis complicating renal allotransplantation. Four had end-to-end anastomosis of the donor renal artery to the recipient hypogastric artery; all PTA's were successful. Three patients had end-to-side anastomosis of the donor renal artery to the recipient external iliac artery; 2/3 PTA's were successful. Prior to PTA, all patients were using several antihypertension medications. Following successful PTA, the mean blood pressure fell from 190 ± 10/120 ± 5 to 132 ± 16/86 ± 9 mm Hg (p < 0.01) and remained at that level for up to 6 mth (average follow-up 2.85 mth) with decreased or no antihypertension medications. Since surgical correction of arterial stenosis is difficult and may endanger the transplant kidney, PTA should be attempted first.
