[Renal cell carcinoma extending into the right atrium; report of a case].
A 62-year-old male was diagnosed through abdominal ultrasonography, with right renal cell carcinoma extending into the inferior vena cava. Surgery was performed because echocardiography revealed the tumor to have reached the right atrium. The portion of the tumor situated in the right atrium was resected under the extracorporeal circulation. Distal part of inferior vena cava was resected with the tumor included. The tumor remaining in the confluence of hepatic veins was removed from the incised end of the inferior vena cava and was detached from the venous wall. Postoperative abdominal echography revealed a small additional tumor mass in hepatic veins. Although this mass was considered to be a remnant of the intravenous tumor, an additional surgical procedure was judged to be impossible. In retrospect, an additional long-axis incision on the inferior vena cava might have enabled us to catch the remnant of the tumor thrombus in the hepatic vein.
