Purposes
The optimal surgical management of renal cell carcinoma with tumor thrombus within the inferior vena cava (IVC) remains to be clarified.
Methods
Sixteen consecutive cases were reviewed. Incision, the IVC clamping position, and the venous drainage procedure were modified according to the tumor thrombus extension level: level I or II (below the hepatic vein, n = 8), level III (above the hepatic vein but below the right atrium, n = 5), and level IV (extending into the right atrium, n = 3).
Results
For level I or II, resection could be simply achieved by clamping the IVC below the hepatic vein, without hemodynamic collapse. For level III, clamping the IVC above the hepatic vein and the hepatoduodenal ligament was required. Venous drainage from the lower body (cannulation to distal IVC) and portal system (cannulation to ileocolic vein) were applied. When opening the IVC, the significant backflow was controlled using cardiopulmonary bypass with drop-in suckers. For level IV, median sternotomy, exposure of the right atrium, and cardiopulmonary bypass were mandatory. With the combination of these approaches, the perioperative mortality rate was 0% and the 5-year overall survival rate was 52%.
Conclusions
A multidisciplinary surgical approach is essential, especially for level III and IV cases.
