ACUTE LIMB ISCHEMIA AFTER TRANSPLANTATION IN A PATIENT WITH PERSISTENT SCIATIC ARTERY

Background. Improved surgical techniques have contributed to a better outcome in kidney transplantation, and graft failure secondary to tech nical complications is unusual. Methods. We describe a surgical compli cation secondary to a rare and unexpected vascular anomaly in a pediat ric renal transplant that resulted in considerable morbidity. Results. Our patient had a persistent sciatic artery as a dominant source of b lood supply to the lower limb. Ligation of this vessel during anastomo sis with the transplant kidney vasculature led to severe ischemic dama ge to the leg. Conclusion. This vascular malformation, if undetected, can lead to serious complications. We present a review of the literatu re regarding this malformation and its management with regard to renal transplantation.
