OBJECTIVE: It was our aim to review our surgical experience with retroperitoneal tumors extending to the vena cava by using cardiopulmonary bypass, deep hypothermia and circulatory arrest. METHOD: We performed this procedure in 15 patients. The ages ranged between 16 and 70 years. The primary malignancies were renal cell carcinoma (n = 13), Wilms' tumor (n = 1) and paratesticular rhabdomyosarcoma (n = 1). RESULTS: There were no operative deaths. One patient died on the fourth postoperative day because of pulmonary embolization. The most common postoperative complications were: 1 patient required surgical reexploration because of hemorrhage, there was transitory renal failure in 3 patients, 1 patient developed a postoperative reactive psychosis and 1 patient developed a subclinical pericarditis. CONCLUSION: We believe that the resection of retroperitoneal malignancies with venous tumor thrombus extension offers, in selected patients, the only chance of reasonable long-term survival. The application of a cardiopulmonary bypass and hypothermia in high level vena cava thrombi is an important advance that has improved the safety and technical efficacy of a difficult surgical undertaking.
