Background:
Improved surgical techniques have contributed to a better outcome in kidney transplantation, and graft failure secondary to technical complications is unusual.
Methods:
We describe a surgical complication secondary to a rare and unexpected vascular anomaly in a pediatric renal transplant that resulted in considerable morbidity.
Results:
Our patient had a persistent sciatic artery as a dominant source of blood supply to the lower limb. Ligation of this vessel during anastomosis with the transplant kidney vasculature led to severe ischemic damage to the leg.
Conclusion:
This vascular malformation, if undetected, can lead to serious complications. We present a review of the literature regarding this malformation and its management with regard to renal transplantation.
