Potential drawbacks of manual aspiration with filter devices in carotid artery stenting:
Background:
Carotid artery stenting (CAS) uses filter protection to prevent embolic events, but filter behavior under retrograde flow is not well understood.
Methods:
An ex vivo silicone model simulated carotid flow using the FilterWire EZ under antegrade, stagnation, and retrograde conditions. Simulated debris of varying sizes was introduced.
Results:
Filters expanded under antegrade flow, collapsed during aspiration, and released debris under retrograde flow. Upon restoring antegrade flow, larger debris was recaptured; smaller particles escaped.
Conclusion:
Filter performance in CAS depends on flow dynamics. Preoperative evaluation of vascular anatomy and procedural planning are key to improving safety.
