Summary

Guidewire fractures during removal can cause complications. Rotational atherectomy offers a solution by cutting the spring wire at the desired location, even if the proximal wire has fractured.

Area of Science:

Cardiovascular Interventions
Medical Device Technology

Background:

Guidewire entrapment is a recognized complication during interventional procedures.
Fracture of the guidewire core can lead to stretching of the spring coil, hindering retrieval.

Observation:

During guidewire removal, proximal core wire fracture can occur.
This fracture can result in the spring wire becoming entrapped distally despite proximal breakage.

Findings:

Rotational atherectomy was employed to address entrapped guidewires with proximal core fractures.
This technique successfully cut the spring wire at the intended site, facilitating removal.

Implications:

Rotational atherectomy provides a viable solution for managing complex guidewire retrieval scenarios.
This method enhances procedural safety and efficacy in challenging interventional cases.
