[Radical nephrectomy and caval tumor thrombectomy with cardiopulmonary bypass combined with right anterior minithoracotomy;report of a case].

Renal cell carcinoma is a tumor with a distinct feature that it can invade the renal vein and grow intravascularly extending to the inferior vena cava (IVC). We herein report a case of a 71-year-old female who presented with a neoplasm that involved the right kidney and an intra-IVC tumor thrombus. We performed radical nephrectomy and tumor thrombectomy under cardiopulmonary bypass through a right anterior mini thoracotomy. The patient was discharged on the 13th day after the surgery without any complication, and is currently in good health at 7 months after the operation.
