Radiodiagnostic methods in determining the structure of tumor thrombus in the inferior vena cava in kidney cancer

Renal cell carcinoma (RCC) is the most common primary tumor of the renal parenchyma. Venous involvement is one of the most important anatomic characteristics of tumor. It is known that venous spread influences the survival of patients with RCC. Tumor thrombosis of IVC in patients with renal cell carcinoma has been reported in 4–10 %. The reference standard for RCC with tumor thrombus remains surgical resection. The structure of thrombus determines some technical difficulties in the management of tumor. Spongeous thrombus correlate with higher risk of thrombus detachment during surgery resulting in PE. Therefore determination of IVC thrombus consistency is very important part of preoperative radiologic assessment of tumor in patients with RCC.
