ABSTRACT Objective To evaluate the effectiveness and outcomes of endovascular treatment of TRAS with PTA. Materials and Methods We searched our prospectively collected database looking at cases of TRAS between January 2005-December 2011. CCT was the gold-standart for diagnosis of TRAS. Parameters analysed comprised technical aspects, arterial blood pressure variation, and renal function. A minimum follow-up of 24 months was considered. Results Of the 2221 renal transplants performed in the selected period, 22 (0.9%) patients were identified with TRAS. Fourteen (63.6%) were male and mean age was 377±14.8years (12-69). Kidney graft was from deceased donnors in 20 (80%) cases. On doppler evaluation, mean blood flow speed after transplantation, at TRAS diagnosis and after TAP was 210.6±99.5, 417±122.7 and 182.5±81.6mL/sec, respectively (p<0.001). For SBP and DBP, there was a significant difference between between pre-intervention and all post-treatment time points (p<0.001). After 1 month of the procedure, there was stabilization of the Cr level with a significant difference between mean Cr levels along time (p<0.001). After a mean follow-up of 16±4.2 (3-24) months, overall success rate was 100%. Conclusions Endovascular treatment with PTA/stenting is a safe and effective option for managing TRAS, ensuring the functionality of the graft and normalization of blood pressure and renal function.

PURPOSE: To analyze the outcome of deceased donor recipients given priority in allocation due to lack of access for dialysis and compare this data to the one obtained from non-prioritized deceased donor kidney transplant recipients. MATERIALS AND METHODS: we reviewed electronic charts of 31 patients submitted to kidney transplantation that were given priority in transplantation program due to lack of access for dialysis from January 2005 to December 2008. Immunological and surgical complications rates, and grafts and patients survival rates were analyzed. These data were compared to those obtained from 100 regular patients who underwent kidney transplantation without allocation priority during the same period. RESULTS: Overall surgical complication rate was 25.8% and 27% in the patients with priority in allocation and in the non-prioritized patients, respectively. There was no statistical significant difference for surgical complications (p = 1.0), immunological complications (p = 0.21) and graft survival (p = 0.19) rates between the groups. However, patient survival rate was statistically significant worse in prioritized patients (p = 0.05). CONCLUSIONS: patients given priority in allocation owing to lack of access for dialysis have higher mortality rate when compared to those non-prioritized.
