    This study details superselective hepatic artery catheterization techniques using five catheter configurations. Tailoring catheters to individual anatomy achieved a 95% success rate in 1,000 patients.

    Area of Science:

    • Interventional Radiology
    • Vascular Surgery
    • Medical Device Technology

    Background:

    • Superselective catheterization of the hepatic artery is crucial for targeted therapies.
    • Variations in celiac artery anatomy necessitate adaptable catheterization techniques.

    Purpose of the Study:

    • To describe techniques for superselective hepatic artery catheterization.
    • To present catheter configurations designed for diverse vascular anatomies.

    Main Methods:

    • Utilized five distinct catheter configurations: simple curve, reverse curve, double curve, modified double curve, and hepatic and splenic curves.
    • Adapted catheterization techniques based on the orientation of the celiac artery (caudad, horizontal, cephalad).
    • Emphasized tailoring catheter selection to individual patient vascular anatomy.

    Main Results:

    • Achieved a 95% success rate in hepatic artery catheterization.
    • Successfully catheterized 1,000 patients using the described techniques.
    • Demonstrated the efficacy of anatomically tailored catheter approaches.

    Conclusions:

    • The described techniques and catheter configurations are highly effective for superselective hepatic artery catheterization.
    • Anatomically tailored catheterization significantly improves success rates.
    • This approach offers a reliable method for hepatic artery access in a large patient cohort.
