Abstract
Intracaval tumor thrombus is one of the characteristic features of advanced hepatocellular carcinoma. To formulate an appropriate operative strategy for removing intracaval tumor thrombi, it is of great importance to accurately diagnose the location, any invasion into the wall of the vena cava, and the extent of intracaval tumor spread. Intravascular ultrasonographic imaging is a novel technology that enables the precise catheter-based assessment of the dimensions and morphology of the vascular structure and any lesions. We have applied this technology to the diagnosis of intracaval tumor thrombi originating from adrenal metastasis secondary to hepatocellular carcinomas. This modality was thus found to be useful in determining the best operative procedure for removing tumor thrombi in the inferior vena cava.
