    A novel retrieval system for Gianturco coils allows for repositioning if malposition occurs. This coil delivery system is effective for routine embolization and high-flow vascular lesions.

    Area of Science:

    • Interventional Radiology
    • Vascular Surgery
    • Neurosurgery

    Background:

    • Gianturco coils are widely used for vascular occlusion.
    • Coil malposition can necessitate repeat procedures.
    • Effective delivery systems are crucial for complex vascular interventions.

    Purpose of the Study:

    • To introduce a new delivery system for Gianturco coils with retrieval capability.
    • To evaluate the safety and efficacy of this system in patients.

    Main Methods:

    • A coaxial cannula delivery system was designed to allow coil retrieval.
    • The cannula features a monofilament cutting mechanism for precise coil release.
    • The system was used in three patients for embolization procedures.

    Main Results:

    • The system successfully facilitated the placement of 48 Gianturco coils.
    • Coil retrieval was possible in cases of malposition.
    • The system was applied to occlude great vein of Galen aneurysms.

    Conclusions:

    • The new delivery system offers enhanced control and safety for Gianturco coil placement.
    • It is suitable for routine embolization and particularly beneficial for high-flow vascular lesions like arteriovenous fistulas and malformations.
