Sriphojanart S Transplant renal artery stenosis (TRAS) is one of the common vascular complications post
kidney transplantation. A retrospective study ofTRAS among transplant recipients at a single transplant
center in Thailand was performed from February 1986 to December 2002. Among 750 cases, 16 cases
(2.1%) of TRAS were identified. Twelve cases (3.3%) were from cadaveric donors and four cases ( 1%)
were from living-related donors (p-value
=
0.034). Most cases presented with progressive deteriora-
tion of kidney graft with or without refractory hypertension. Doppler ultrasonography was used for
initial screening followed by renal angiography. Fifteen cases were treated by Percutaneous Trans-
luminal Angioplasty (PTA) with a 73 per cent success rate. Five cases underwent surgical revascula-
rization with an 80 per cent success rate. Two cases (13%) of successful PTA showed recurrent stenosis
with 46 months follow-up which were successfully treated by repeated PTA with stents.
