Objectives:
Renal cell carcinoma with a tumor thrombus extending into the supradiaphragmatic inferior vena cava (IVC) and right atrium represents a challenge to the surgical team. We describe a technique that can be used to resect these tumors safely through a transabdominal approach without recourse to cardiopulmonary bypass (CPB) or entry into the thoracic cavity.
Methods:
Between May 1997 and August 2004, 59 patients (mean age 61 years) underwent surgical resection of a renal tumor extending into the IVC by techniques developed with the intention to avoid sternotomy and CPB. In 7 patients (12%), the tumor thrombus extended into the supradiaphragmatic IVC and right atrium. Complete surgical resection was successful through a transabdominal approach without CPB in all 7 of these patients.
Results:
In the 7 patients who underwent the described technique, the median age was 71 years (range 51 to 80). The mean operative time was 7 hours, 47 minutes. The mean estimated blood loss was 2514 mL (range 500 to 6000). The mean number of blood units transfused was 4.7 (range 0 to 11). One patient died in the immediate postoperative period of cardiac arrhythmia. The median follow-up was 11.1 months, and 5 patients were disease free.
Conclusions:
In select cases, renal cell carcinoma extending into the supradiaphragmatic IVC and right atrium can be resected without the use of CPB. We describe our technique.
