Experiences regarding intervention in renal transplantations by nephrologists

At our institute since January 2007, we encountered 8 cases of transplant renal artery stenosis, 6 arteriovenous fistulas and a case of extra and intrarenal pseudo aneurysm. All patients with transplant renal artery stenosis underwent angioplasty and stenting successfully both in terms of anatomical correction and improvement in blood pressure control as well as graft function. One patient had arterial stenosis and arteriovenous fistulas both and he underwent simultaneous stenting and coil embolization. Three patients with fistulas who had significant bleeding underwent successful coil embolization while 2 patients who were asymptomatic are under close surveillance. One patient each who had extra and intrarenal pseudo aneurysm underwent successful endovascular covered stent grafting and multiple coil embolization respectively. Vascular interventions in renal allograft by experienced nephrology unit can achieve good success with minimal complications.
