Cardiovascular Surgery in the Management of Malignant Renal Neoplasms: Survey of 187 Cases in the Literature

AUTOR(ES)
RESUMO

Transmural or endovascular invasion of regional veins is often a characteristic of malignant renal neoplasms. Tumor thrombus that ascends in the inferior vena cava and sometimes invades the heart seldom adheres to intima. Radical surgical management of malignant renal neoplasms necessitates concomitant extraction of tumor thrombus. This may be achieved by cavotomy alone, but often resection of portions of the suprarenal inferior vena cava (either partial mural cavectomy, or circumferential cavectomy) is also required. Atriotomy is mandatory whenever intracardiac tumor thrombus exists.
