Summary

Living donor kidney transplants with arterial abnormalities can achieve excellent outcomes. Microsurgical reconstruction, especially bench reconstruction for diseased arteries, significantly improves graft survival rates in kidney transplantation.

Area of Science:

  • Nephrology
  • Transplant Surgery
  • Vascular Surgery

Background:

  • Graft survival in kidney transplantation can be compromised by arterial abnormalities in donor kidneys.
  • Living donor (LD) kidney transplants are susceptible to issues related to multiple renal arteries or renovascular disease.

Purpose of the Study:

  • To evaluate the outcomes of living donor kidney transplants based on graft arterial anatomy and revascularization techniques.
  • To assess the impact of microsurgical reconstruction on graft survival in the presence of arterial abnormalities.

Main Methods:

  • A series of 261 living donor kidney transplants were classified into three groups based on arterial anatomy and reconstruction methods.
  • Group I: Single healthy renal artery. Group II: Multiple arteries reconstructed intracorporeally. Group III: Diseased artery or multiple arteries reconstructed ex vivo (bench reconstruction).

Main Results:

  • One- and 3-year graft survival rates were 91% and 87% (Group I), 82% and 82% (Group II), and 100% and 100% (Group III).
  • A recent series of 53 LD transplants with aggressive microsurgical bench reconstruction achieved 100% 3-year graft survival, even with diseased single arteries.

Conclusions:

  • Microsurgical bench reconstruction is a highly effective technique for managing living donor kidneys with arterial abnormalities.
  • Aggressive reconstruction strategies can lead to excellent long-term graft survival in kidney transplantation, overcoming challenges posed by donor kidney vascular conditions.
