Vena cava thrombosis can represent a surgical challenge in the context of kidney transplantation. Selection of venous drainage in this setting should provide adequate venous outflow and minimize the risk of thrombosis and subsequent graft failure. We report the case of an adult female patient who presented for a deceased donor kidney transplant with incidental finding of complete inferior vena cava (IVC) and obliteration. After exploration of the retroperitoneal space up to the level of the obliterated IVC, a collateral venous branch was identified at the confluence of the right and left iliac veins. This was utilized as the site of the renal vein venous anastomosis. The patient recovered with immediate graft function. Follow-up ultrasound demonstrated patent vasculature without evidence of thrombosis or outflow obstruction. This report offers a surgical alternative to proceed in the case of an adult with unsuspected caval system obliteration.
