Venous reconstruction using a Y‐shaped saphenous vein in kidney transplantation: A report of three cases

Abstract

Introduction Transplantation, especially, of the right kidney may be difficult to properly choose the main drainage vein due to abundance of renal veins with the thin wall and the small diameter. Therefore, we report three cases, wherein anastomosis‐related complications may be avoided by using a reconstructed Y‐shaped major saphenous vein graft. Case presentation The first case was a case of congestion when anastomosed with a trifurcated renal vein which ligated branch. The second case was a case of donated kidney with three renal veins, which were all short, small, and thin‐walled. The third case was a case of donated kidney with four renal veins. Two of them were unused, though the other two veins were short and thin‐walled with equal diameters. In all of three cases, renal veins were anastomosed with Y‐shaped saphenous vein graft. Conclusion Y‐shaped saphenous vein graft is possibly effective for such reconstructions as it may prevent anastomosis‐related complications.

Anatomic characteristics and novel transplantation model of the canine uterus

“…This reconstruction had no complications in any cases. This procedure has not been reported in uterine transplantation but was recently mentioned in the context of kidney transplantation [ 17 ]. Although the anatomy of the canine uterus differs distinctly from the human anatomy, the results of this study supply information regarding the anatomy of the canine uterus and immunosuppression during the transplantation process.…”

Editorial Comment to Venous reconstruction using a Y‐shaped saphenous vein in kidney transplantation: A report of three cases

“…In this issue of the IJU Case Reports, Miyauchi et al reported three living-donor kidney transplant cases which the two donor right renal veins were reconstructed using a major Y-shaped saphenous vein. 1 In the case of living-donor renal transplantation, the donor left kidney is usually selected because the right kidney has shorter venous length than the left kidney. 2 If there are minor abnormalities in the donor right kidney, the normal donor left kidney is preserved.…”

“…4 When there are two veins, as reported in Miyauchi et al's study, this Y-shaped saphenous vein graft seems to be effective in preventing outflow obstruction and to achieve the lengthening of the right allograft renal vein. 1 I would like to use the Y-shaped saphenous vein graft in case of short and multiple allograft renal veins.
