Superselective arterial embolization of the rat liver

Area of Science:

• Hepatology
• Interventional Radiology
• Surgical Oncology

Background:

• Superselective transcatheter arterial embolization (TACE) is an established treatment for hepatic tumors.
• Evaluating TACE efficacy requires reliable experimental models.

Purpose of the Study:

• To develop and validate an experimental rat liver model for evaluating superselective transcatheter arterial embolization.
• To enable comparative analysis of embolized versus non-embolized liver lobes.

Main Methods:

• Retrograde catheterization of the superior pancreaticoduodenal artery in rats.
• Superselective embolization of intrahepatic arterial branches and sinusoids in specific liver lobes using Gelfoam powder.
• Utilizing 1.2 and 1.5 mg of Gelfoam for embolization.

Main Results:

• Successful development of a rat liver model for superselective TACE.
• Adequate performance of superselective embolization, mimicking clinical procedures.
• Establishment of a platform for comparative evaluation of embolized and non-embolized liver lobes.

Conclusions:

• The developed rat liver model accurately replicates clinical superselective TACE.
• This model provides a valuable tool for comparative assessment of TACE treatment responses.
• Further research can utilize this model to optimize hepatic tumor treatments.
