Area of Science:

  • Interventional Radiology
  • Vascular Surgery

Background:

  • Hepatic arterial embolization is a critical procedure for various liver conditions.
  • Superselective catheterization of hepatic arteries is often necessary for effective treatment.
  • Navigating tortuous vessels and accessing segmental arteries can be technically challenging.

Purpose of the Study:

  • To evaluate the feasibility and utility of a coaxial catheter system for superselective hepatic arterial embolization.
  • To assess the capability of the Tracker Hi-Flow catheter in complex hepatic arterial interventions.

Main Methods:

  • A coaxial catheter system, specifically the Tracker Hi-Flow catheter, was employed.
  • The system was used in 38 hepatic arterial embolization procedures across 20 patients.
  • The technique focused on superselective catheterization of segmental arteries and navigating tortuous vessels.

Main Results:

  • The Tracker Hi-Flow catheter facilitated 38 hepatic arterial embolizations.
  • The coaxial system's ability to superselectively catheterize segmental arteries was crucial.
  • The technique proved effective in negotiating tortuous hepatic vessels, enabling previously unfeasible embolizations.

Conclusions:

  • The coaxial catheter system, utilizing the Tracker Hi-Flow catheter, is a valuable tool for superselective hepatic arterial embolization.
  • This technique enhances the ability to treat complex hepatic arterial anatomies.
  • It expands the feasibility of embolization in challenging vascular structures.
