BACKGROUND The endovascular approach has shown high initial technical success rates, good patency rates, and minimal complications in treating transplant @entity2791 (TRAS). The objective of this study was to describe our experience with an endovascular approach to TRAS. MATERIAL AND METHODS We performed a retrospective single-institutional review of all kidney transplant procedures performed at our institution from September 2009 to September 2014. All consecutive cases of TRAS were included. RESULTS From a total of 183 kidney transplantations, 16 @entity1 had TRAS. Mean time from transplantation to TRAS diagnosis was 201.8 days. Stenoses or hemodynamic significant kinkings were located at the @entity254 (7), proximal (5) and middle (4) portions of the transplant artery. All @entity1 were treated with angioplasty and primary balloon-expanding stenting. Early technical success was 93.75% and local complication rate was 12.5%. No @entity204 occurred. Mean serum @entity1011 level dropped from 3.87 mg/dL to 2.91 mg/dL after 24 hours; 1.85 mg/dL after one month; and 1.67 mg/dL after three months (P<0.05). Mean estimated glomerular filtration rate increased from 31.60 mL/min to 39.53 mL/min after 24 hours; 50.92 mL/min after one month; and 55.05 mL/min after three months (P<0.05). Doppler ultrasound criteria normalized after the procedure. Number of classes of antihypertensive drugs was not different before and after the procedure (P=0.38). Mean follow-up time was 9.75 months. One @entity1 had a @entity256 and required surgical intervention to restore graft function. CONCLUSIONS The endovascular approach to TRAS with primary balloon-expanding stenting was safe and had a high rate of technical success. It was effective for restore and maintain the renal function in transplant kidney grafts with a low rate of @entity256 .
