Splenic Rupture During Occlusion of the Porta Hepatis in Resection of Tumors with Vena Caval Extension

The surgical management of renal cell carcinoma with intraluminal extension into the vena cava is technically demanding.

To our knowledge we report the first 2 cases in which intraoperative splenic rupture occurred and discuss possible causes of this complication.
