HCC
Using Lipiodol® Ultra-Fluid (Iodinated ethyl esters of fatty acids of poppy seed oil) in cTACE procedure
STANDARDIZATION IS KEY FOR REPRODUCIBLE AND OPTIMAL cTACE PROCEDURE
Lipiodol®-drug droplets are deformable & heterogeneous in size(1,2)

Droplet deformability |
Lipiodol®-drug droplets achieve transient dual embolization (arterial & portal vessels)(3)
PV = Portal Venule
HA = Hepatic Arteriole
BD = Bile Duct
HV = Hepatic Venule
HC = Hepatocytes
Peribiliary plexa allow Lipiodol®-Drug droplets shunting from hepatic artery to portal vein(4)
Radiological evidence of dual vascularization of HCC
 |
GRADE 0Arterial enhancement of the tumor |
 |
GRADE 1Early venous enhancement thanks to the peribiliary vascular plexa |
 |
GRADE 2Full visualization of the arterioportal vascular bed |
