Core Tip
Core Tip: Venous outflow complications during kidney transplantation are uncommon but may threaten immediate graft survival when conventional iliac venous drainage is not feasible. We describe a rare case of unexpected external iliac vein atrophy encountered intraoperatively, where renal allograft venous outflow was successfully salvaged using an ovarian vein bypass augmented with an autologous great saphenous vein conduit. This report emphasizes the importance of flexible intraoperative strategies and demonstrates that the ovarian vein can be adapted as an alternative venous drainage route after appropriate reconstruction, providing a practical solution for unexpected iliac venous insufficiency during renal transplantation.
