Living Related Renal Transplantation Using a Saphenous Vein Graft: A Case Report.

We report a case of living related renal transplantation that used the recipient's saphenous vein as a graft to extend the length of the right donor renal vein. A 41-year-old woman underwent ABO-incompatible living related renal transplantation from her 74-year-old mother in November 2014. A retroperitoneal laparoscopic right donor nephrectomy was performed, because the right kidney showed a cyst on preoperative computed tomography. As the right kidney after donor nephrectomy had a short renal vein and the kidney was large at 280 g, anastomosis with the external iliac vein was difficult. Therefore, we obtained the recipient's 15-cm-long right saphenous vein and created a 1 cm saphenous vein graft. We anastomosed 1 side of the saphenous vein graft to the allograft renal vein in bench surgery and performed end-to-side anastomosis of the other end to the recipient's external iliac vein. The allograft renal artery was used to perform end-to-end anastomosis to the recipient's internal iliac artery. Allograft kidney function was good after transplantation. When the longer axis of the renal graft vein is short, as in the right kidney, a saphenous vein graft may be useful.
