Suprarenal Filter Placement in the Inferior Vena Cava to Prevent Tumor Emboli During Radical Nephrectomy in Renal Cell Carcinoma Invading the Inferior Vena Cava / 대한비뇨기과학회지

ABSTRACT

A renal cell carcinoma with tumor thrombus extension into the inferior vena cava occurs in approximately 5 percent of cases. Despite invasion of the inferior vena cava, an aggressive surgical approach for these neoplasms is recommended, but pulmonary and tumor embolisms have been common complications. Therefore, the prevention of tumor emboli during operation is necessary. Placement of a suprarenal filter in the inferior vena cava has become the procedure of choice for preventing tumor emboli during a radical nephrectomy.
