Cardiac surgery in patients with moderate renal impairment.

Background: There is a paucity of information concerning the results of cardiac surgery in patients with moderate impairment of renal function. We reviewed our recent experience to determine the results of operation and the long-term outcome.

Methods: Since January 1992, we have performed cardiac surgical procedures utilizing total cardiopulmonary bypass on 57 adult patients with preoperative serum creatinine values > or = 2.

Cavoatrial tumor thrombectomy using cardipulmonary bypass without circulatory arrest.

Of 29 patients with inferior vena caval tumor thrombus, 14 with supradiaphragmatic extension were deemed suitable for operation. Patients (age, 7.5 to 70 years) had renal cell carcinoma (n = 8), Wilms' tumor (n = 2), transitional cell carcinoma (n = 1), and adrenal carcinoma (n = 3).
