Introduction: Kidney transplantation (KTx) is the therapy of choice in patients with end-stage renal disease. Aorto-iliac calcifications (AIC) are a relative contra-indication for KTx, even though the influence on patient and graft survival remains poorly explored. The aim of this study is to assess the impact of aorto-iliac calcifications on patient and graft survival using the TASC II classification.

Methods: This retrospective single-center study included all KTx recipients from 2000-2016 who had imaging-proven pre-transplantation aorto-iliac stenotic lesions. Patients were classified according to the TASC II classification. All patients transplanted between 2007-2011 without aorto-iliac stenotic lesions were used as a control group. Primary endpoints were patient and graft survival. Cox proportional hazards model was used to evaluate risk factors for mortality and graft loss.

Results: Aorto-iliac stenotic lesions were observed in 78 patients before kidney transplantation. In total, 773 patients were included as a control group. Overall patient survival was decreased for every TASC II class (TASC II A: p=.001; B: p=.004, C: p<.001, D: p<.001). No significant difference was found for 90-day mortality (TASC II A p=.165; B p=1.000; C p=1.000) and 1-year mortality (TASC II A p=.143; B p=1.000; C p=1.000) in patients with TASC II A, B or C lesions. Patients with TASC II D lesions had significantly higher 90-day (p=.006) and 1-year (p <.001) mortality. Death-censored graft survival was not significantly decreased for TASC II A, B and C compared to the control group (TASC II A p=.792; B p=.950; C p=.160). Multivariate Cox model showed that any TASC II lesion was not a predictor of overall mortality (hazard ratio (HR) 1.52 confidence interval (CI) 0.94-2.46) or graft loss (HR 1.72; CI 0.94-3.17).

Conclusion: Kidney transplantation is a safe procedure in patients with TASC II A, B and C lesions. Graft survival is unaffected by aorto-iliac stenotic lesions. Therefore, aorto-iliac calcifications should not be a contra-indication for kidney transplantation.
