title: [Surgical treatment of caval thrombosis caused by parenchymal renal neoplasms].
abstract: The incidence of renal cell carcinoma with a vena caval tumour thrombus has been reported in the literature, form 4% to 19%. Vena caval involvement causes serious diagnostic and therapeutic problems. Surgical treatment is usually conditioned by the tumor thrombus cranial extension and the possible invasion of the vena caval wall. Using Diagnostic Imaging (ECHO, CAT, MRI) we are able to establish the real presence, dimension and extension of the tumor thrombus, but we can not evaluate precisely its nature or the infiltration of the vena caval wall. We report our own experience in 27 patients with renal cell carcinoma extending into the vena cava (22 cases with tumor thrombus extending under the diaphragm and 5 cases over the diaphragm) and describe our favourite approach for thrombus extending into the right atrium using extracorporeal circulation, profound hypothermia and cardiac arrest (3 cases). From our data, we believe that the vena cava involvement doesn't make the prognosis any worse, if it isn't associated with the infiltration of the vena caval wall and nodal disease.
