Abstract:
Objective:To evaluate the mid-term results of endovascular treatment for transplant renal artery stenosis (TRAS).Methods:The clinical and follow-up data of TRAS patients undergoing endovascular treatment at the First Affiliated Hospital of Zhengzhou University from Jan 2014 to Jan 2021 were retrospectively analyzed.Results:A total of 2 230 patients underwent kidney transplantation, 78 cases(3.6%) developed TRAS, among those 27 patients received endovascular treatment and followed-up from 12 to 80 months(mean 36 months). Thirteen patients (48.1%) underwent renal graft angiography and balloon dilatation, of which 2 patients underwent stent placement, 14 patients (51.9%) underwent renal graft angiography with balloon dilatation and stenting. The serum creatinine 2 weeks postoperatively and 12 months postoperatively were 127.6 μmol/L (47-220 μmol/L) and 103.4 μmol/L (63-166 μmol/L), respectively, significantly lower than the preoperative 217.1 μmol/L (98-541 μmol/L), ( P<0.05). Glomerular filtration rate (GFR) before surgery was 8.3-105.3 ml/min, 2 weeks and 12 months after surgery compared to 24.6-132.2 ml/min and 47.3-113.9 ml/min( P<0.05). The preoperative peak systolic velocity (PSV) of the transplanted renal artery during the systolic phase was 234 cm/s (75-457 cm/s), compared to 129 cm/s (52-290 cm/s) ( P<0.05) 2 weeks and 118 cm/s (57-300 cm/s) 12 months postoperatively ( P<0.05). During the follow-up period, 2 patients (7.4%) died of multiple organ failure. Conclusions:TRAS is the most common vascular complication after kidney transplantation. Endovascular treatment has a high success rate and low complication rate.
