[Anesthetic management of radical nephrectomy using cardiopulmonary bypass in patients with vena caval or atrial extension of renal cell carcinoma].

We experienced three cases of anesthesia for radical nephrectomy using cardiopulmonary bypass in patients with vena caval or atrial extension of renal cell carcinoma. Pulmonary thromboembolism (PTE) did not occur. One patient with preoperative hepatorenal dysfunction died of multiple organ failure. Other two patients were discharged in good condition. We must pay attention to treatment of intraoperative PTE and massive hemorrhage, prevention of organ damage, and presence of preoperative organ dysfunction.
