The surgical approach for the inferior vena cava leiomyosarcoma including the confluence of right renal vein: A case report of patch venoplasty with right renal vein reimplantation after complete tumor resection

ABSTRACT

Surgical approaches for leiomyosarcoma of the inferior vena cava (IVC) are based on tumor location. Radical resection for the IVC leiomyosarcoma involving the renal vein has traditionally included nephrectomy with renal vein ligation or kidney autotransplantation. A 51-year-old woman was admitted for elective surgery for the tumor of IVC. At surgery, the tumor was located in front of IVC, abutted with right renal vein. After the tumor resection, IVC reconstruction involved the patch cavoplasty with cryopreserved cadaveric vein graft and the implantation of the right renal vein into the inferior IVC. The patient recovered fully without any postoperative complications including kidney function change. This technique could be adopted for tumors located in front of IVC involving renal veins, provided complete resection of the tumor with a comfortable resection margin is possible.
