Hepatic embolization with an open-ended guide wire.

D M Coldwell

    Radiology
    |October 1, 1987
    PubMed
    Summary
    This summary is machine-generated.

    A new steerable guide wire simplifies catheterization of difficult-to-navigate vessels and hepatic artery embolization. Optimal polyvinyl alcohol foam suspension for embolization with this wire is 0.6 mg/mL saline.

    Area of Science:

    • Interventional Radiology
    • Vascular Surgery

    Background:

    • Catheterization of tortuous vessels presents significant challenges.
    • Hepatic artery embolization requires precise delivery of embolic agents.

    Purpose of the Study:

    • To evaluate the utility of a novel open-ended, steerable guide wire in complex vascular interventions.
    • To determine optimal embolic agent suspension for use with the new guide wire.

    Main Methods:

    • Case series of four patients undergoing vascular procedures.
    • Utilized a new steerable guide wire for catheterization and embolization.
    • Investigated different concentrations of polyvinyl alcohol foam suspension.

    Main Results:

    • The steerable guide wire proved invaluable for catheterizing tortuous vessels.

  • Successful hepatic artery embolization was achieved without a catheter.
  • A more dilute polyvinyl alcohol foam suspension (0.6 mg/mL saline) prevented wire occlusion.

    • Conclusions:

    • The open-ended steerable guide wire is a valuable tool for complex vascular catheterization.
    • This guide wire facilitates direct hepatic artery embolization.
    • Optimized embolic suspension is crucial for successful procedures with this device.
