Abstract:
Objective To report our experience of interventional procedure for arterial complications in post renal transplantation and to evaluate its clinical value.Methods In a retrospective analysis of renal transplantations in our center,52 cases of renal allograft artery abnormalities had taken angiography.Interventional procedure included transluminal angioplasty of arterial stenoses,treatment of arterial occlusion,and embolization of pseudoaneurysm.Results Renal allograft artery abnormalities included artery stenosis (n=21),artery thrombosis (n=13) and embolision (n=1),renal artery pseudoaneurysms (n=2),and decrease of renal artery flow (n=3).Of the 21 artery stenosis,2 grafts with artery stenosis were lost because the stenosis could not be corrected,and 3 with mild stenosis received no treatment.Another 16 accepted renal artery angioplasty (balloon dilation,n=12,and stent implantation,n=4).14 achieved long-term allograft function.1 graft was lost because renal function failed to recover.Restenosis occurred in one stent implantation,and lost the allograft function after secondary dilation.13 cases received thrombolytic therapy through artery catheter for thrombosis and 9 achieved long-term allograft function.Thrombolyses failed in 3 cases,and renal function failed to recover in 1 case.One pseudoaneurysm received stent implantation after embolization,and got a short-term allograft function.The other one received allograft excision.Conclusion Intravascular interventional therapy will be the first-line therapy for any indications of complication in post renal transplantation,and it can surely save the kidney in a majority of instances.
