[Radical extirpation of a left-sided hypernephroma with tumor thrombus in the vena cava inferior (author's transl)]. / Radikale Exstirpation eines linksseitigen Hypernephroms mit Tumorzapfen in der Vena cava inferior.

A radical nephrectomy of a left-sided renal cell carcinoma with extension of the tumor thrombus into the vena cava as far up as the right atrium is described. The right kidney has no venous collateral system, therefore ligation of the right renal vein and resection of the tumor-invaded vena cava is not possible. A left radical extended nephrectomy, if necessary, with interposition of a vessel prosthesis, increases the prognosis and must be considered the therapy of choice.
