Treatment of renal transplant artery stenosis by percutaneous transluminal dilatation.
Transluminal arterial dilatation using a balloon catheter was performed in four patients with renal allografts and transplant artery stenosis. In three patients the procedure was uncomplicated and resulted in reduction in mean blood pressure from 180/100 mm Hg to 135/85 mm Hg immediately after and 135/90 mm Hg at a mean of eight months after angioplasty; renal function remained stable. In one patient with two stenoses the procedure was abandoned because of inaccessibility of the stenotic sites to the dilatation catheter; however, reversible acute renal failure ensued. Percutaneous transluminal angioplasty may thus offer a successful alternative to conventional surgical techniques in renal transplant artery stenosis in suitable patients.
