title: Leiomyosarcoma of the inferior vena cava involving the renal veins: a simple method of right renal vein reimplantation.
abstract: In this report we describe a case of leiomyosarcoma of the inferior vena cava involving the renal veins. The abdominal computed tomography scan showed a tumor in the infrahepatic portion of the inferior vena cava and the confluence of the renal veins. After resection of the tumor, venous reconstruction involved the replacement of the inferior vena cava with a prosthetic graft and the implantation of the right renal vein into the portal vein. The left renal vein was ligated distally, with preservation of collateral pathways. To our knowledge, no other reports of such venous reconstruction have been published. After a follow-up of 30 months, the patient has shown no further symptoms, and the abdominal computed tomography scan demonstrates patency of the renal portal anastomosis. Tests indicated normal renal and hepatic function, suggesting good tolerance of the renal portal anastomosis. We believe that the technique described in this report should be adopted routinely for tumors located in the renal veins, provided complete resection of the tumor with a comfortable resection margin is possible.
