[Surgical treatment under extracorporeal circulation for renal cell carcinoma with tumor thrombus in inferior vena cava].
Three cases of renal cell carcinoma with tumor thrombus extending into the inferior vena cava are reported. Radical nephrectomy and thrombectomy were performed under extracorporeal circulation in all the cases. The level of tumor thrombus was preoperatively determined by computed tomography, magnetic resonance imaging or venacavography. The tumor thrombus extended into the right atrium in one, and above the hepatic vein in two cases. One patient whose thrombus reached the right atrium died of multiple metastasis of renal cell carcinoma 5 months after operation. Another patient with lung metastasis was given interferon-alpha and is alive 5 months after operation. The other patient is clinically free of disease and in good health 7 years after operation. We believe that extracorporeal circulation allows an opportunity to resect the tumor thrombus in a controlled situation, and makes the operation safer.
