Relationship between Arterioplasty and Renal Prognosis in Living Donor Renal Transplantation

Abstract

Renal transplantation with multiple arteries has been reported to increase the risk of causing complications and poor renal function compared to the transplantation with a single artery.

We performed 166 living donor renal transplantations at our hospital over a 7-year period from 2015 to 2021. Excepting 12 patients whose multiple arteries were ligated at the branches, 154 patients were enrolled in a retrospective cohort study. The patients were divided into two groups : the arterioplasty group (AP group, n=37) and the simple anastomosis group (SA group, n=117). The primary end point was renal function. The secondary endpoints were intraoperative arterial re-anastomosis, graft survival, and patient survival. When compared for renal function between both groups, the serum creatinine (s-Cr) level at discharge was 1.68±0.93 mg/dL in the AP group and 1.36±0.40 mg/dL in the SA group (p=0.157). The s-Cr level at 1 year later was 1.52±0.66 mg/dL in the AP group and 1.29±0.38 mg/dL in the SA group (p=0.197).

Intraoperative arterial reconstructions were performed for 3 (8%) patients in the AP group and 6 (5%) patients in the SA group, with no significant difference between the groups (p=0.449). Graft survival at 1 year later was 97.3% in the AP group and 98.3% in the SA group (p=0.175). Patient survival at 1 year later was 100% in both groups.

Arterioplasty in living donor renal transplantation with multiple arteries was effective and safe.
