Abstract:
A 70-year-old woman was admitted to our hospital complaining of upper abdominal pain. Computed tomography revealed a 6-cm tumor next to the inferior vena cava (IVC). Venography revealed obstruction of the IVC, and venous return was via collateral circulations. Right nephrectomy and tumor resection of the middle part of the IVC was performed. The left renal vein, which was invaded by tumor, was divided without venous reconstruction. Pathological diagnosis was leiomyosarcoma. Postoperatively hemodialysis was needed for a month, but maintenance hemodialysis was avoided. Leiomyosarcoma of the middle part of the IVC sometimes invades bilateral kidneys, and sometimes it is not possible to reconstruct the renal vein. It is important to recognize collateral circulation by preoperative angiography, and to protect such circulation during operation.
