Interventional therapy for stenosis and aneurysm in renal graft artery: report of 9 cases.

Objective To study the interventional therapy for renal graft artery stenosis and aneurysm patients with renal transplantation to further improve the survival rate of the graft. Methods Seven patients with of renal graft artery stenosis received balloon dilatation of the stenotic artery, followed by stent implantation. For renal graft artery aneurysm in another 2 patients, thrombin infusion and stent implantation were respectively performed. Results The condition was successfully managed in 6 of the 7 patients with renal artery stenosis, whose serum Cr levels dropped to below 106 μmol/L 3 d after the operation. Thrombin infusion in one of the 2 patients with renal artery aneurysm caused thrombus in the renal graft and then aneurysm rupture, resulting in final graft loss. The other aneurysm case was successfully managed with stent implantation. Conclusions Interventional therapy as balloon dilatation combined with stent implantation is ideal for treating renal graft artery stenosis, and stent implantation constitutes an important management for artery aneurysm in the renal graft.
