Background:
This is the first clinical report on experience in the use of the Gore embolic filter in carotid interventions. It was designed as a guidewire and embolic protection system in carotid, peripheral, and coronary interventions. The ability to capture debris is driven by the frame of the filter, which is designed to improve vessel wall apposition and allows a short landing zone.
Methods:
We report the results of the first 20 consecutive patients undergoing carotid artery stenting using the Gore embolic filter in our institution. We analyzed technical success as well as the occurrence of transient ischemic attack (TIA), stroke, or death periprocedurally and through 30 days of follow-up. Mean patient age was 72 years and 12 patients (60%) were male. Seven patients were symptomatic and 4 patients suffered recurrent neurological events.
Results:
Technical success was achieved in all procedures. In 1 patient, the retrieval catheter was caught between the proximal struts of the stent and required further retrieval maneuvers. Within 30 days of follow-up, 1 patient had a TIA. No stroke, death, or myocardial infarction occurred.
Conclusion:
This initial experience suggests that the Gore embolic filter device can be used safely for distal embolic protection during carotid stenting procedures with high technical success.
