Abstract
Balloon-occluded trans-arterial chemoembolization (B-TACE) achieves high accumulation of lipiodol in hepatocellular carcinoma (HCC) nodules and enables forceful retrograde injection of embolization materials into the collateral vessels, which improves local control of HCC nodules. Ultra-selective TACE (U-TACE) is also known to improve local control of HCC nodules. We consider the reason why U-TACE improves local control to also be forceful injection of embolization materials. In this paper, we discuss the mechanism of B-TACE and U-TACE, and disclose the know-how of B-TACE.
