Renal cell carcinoma (RCC) with cavoatrial extension is a rare and complex problem. Complete resection is difficult but correlates with favorable patient outcomes. We present 2 cases of successful reoperative resections of recurrent RCC in patients with level III-IV cavoatrial involvement. We used a thoracoabdominal approach, peripheral cannulation, and hypothermic circulatory arrest. We advocate this novel approach as a successful means of avoiding a more difficult reoperation.

ABSTRACT: The management of malignant tumours invading the inferior vena cava (IVC) generally requires a high-risk surgery with low long-term benefits. Surgical treatment with resection and/or embolectomy of the IVC may, however, be beneficial in selected patients. We describe our experience with regard to patient selection, operative technique and outcomes through a standardized and simplified approach.
Between 1996 and 2012, 37 patients underwent extended resection of malignant tumours invading the IVC. Tumour infiltration was located at the hepatic and suprahepatic segment in 23 patients (62%), the renal segment in 6 (16%), and the infrarenal segment in 8 (24%). Fourteen patients (38%) had right heart involvement, of whom 5 had a tumour thrombus located in the pulmonary arteries (PA).
All the patients underwent a median laparotomy. A sternotomy with full liver mobilization was performed for tumours involving the PA, or the retrohepatic or supradiaphragmatic IVC. Cardiopulmonary bypass was performed in 15 patients (41%), with deep hypothermic circulatory arrest (DHCA) in 5 (14%). The 30-day mortality rate was 5.4%. The 1-, 5- and 10-year survival rates were 68.1, 45.7 and 40%, respectively, with a median survival of 18 months. Incomplete resection (R1 or R2) was the only parameter found to have a significant negative effect on survival (P = 0.003).
Radical resection of malignant tumours invading the IVC is feasible in carefully selected patients and may require CPB with or without DHCA. Morbidity and mortality are low and the survival rates acceptable, particularly in patients with complete resection of the tumour.

ABSTRACT: Thoracic incisions are the portals of choice for accessing thoracic organs. There are instances, however, that more than one incision are required at the same or a later stage, in order to access other, thoracic or extrathoracic, organs for more complicated procedures. Then again, a single thoracic incision may offer more than adequate access to extrathoracic organs and in selected cases becomes valuable surgical approach to organs of the upper abdomen or the contralateral hemithorax. The experience with this technique is discussed.
