    Summary
    This summary is machine-generated.

    Flow-controlled silicone fluid embolization offers a method for targeted embolization when selective injection is not feasible. This technique preserves the proximal feeding vessel by using a specialized catheter and radiopaque silicone fluid for precise emboli distribution.

    Area of Science:

    • Interventional Radiology
    • Vascular Surgery
    • Biomedical Engineering

    Background:

    • Selective arterial embolization is a common interventional procedure.
    • Challenges arise when direct selective injection is not achievable.
    • Preservation of the proximal feeding vessel is often critical.

    Observation:

    • A modified double-lumen balloon catheter was developed.
    • Silicone fluid was rendered radiopaque using tantalum powder.
    • The fluid had predetermined viscosity and vulcanization characteristics.

    Findings:

    • Flow control is achieved by manipulating the balloon catheter in the proximal artery.
    • This manipulation allows for controlled distribution of emboli to distal arterial sites.
    • The technique facilitates embolization in challenging anatomical situations.
