    Abstract:
    BACKGROUND: Neurologic events associated with distal embolization of debris during percutaneous carotid artery stenting complicate the procedure. Filter devices for cerebral protection potentially reduce the risk of embolization and other neurologic events. We studied the feasibility, safety, and efficacy of carotid artery stenting with a filter device. METHODS AND RESULTS: Between January 2002 and January 2003, a total of 22 consecutive patients (30 lesions) who had >70% diameter stenosis of the internal carotid artery underwent carotid artery stenting with filter protection at our institute. The mean age of the patients was 64+/-9 years; 14 were men and 8 women, and 15 had neurologic symptoms. A stent was successfully implanted in 29 lesions. It was possible to position a filter device in all the 29 lesions. Neurologic complications during the procedure, in the hospital, and at 30-day clinical follow-up occurred in 2 patients. One patient suffered a minor stroke that resolved within 24 hours. None of the patients had a major embolic stroke. There was one death from intracerebral hemorrhage related to hyperperfusion and the use of a glycoprotein IIb/IIIa inhibitor. CONCLUSIONS: Filter protection during carotid artery stenting seems technically feasible, safe, and effective. In the present study, the incidence of embolic neurologic events was low.
