Abstract:
Objective To analyze the effect and safety of cerebral protection filter in carotid artery and stenting(CAS) for the treatment of severe symptomatic carotid artery stenosis.Methods Elective CAS with the use of cerebral protection filters were undergone in 26 consecutive patients with severe carotid artery stenosis.The filter devices were advanced through lesions and opened distal to the lesions followed by CAS.The incidence of cerebral ischemic events and the debris collected in the filters were observed and analyzed.Results In all the patients,it was feasible and successful to position the filters devices in the internal carotid artery.After the filter devices were positioned,CAS were performed successfully in all the 26 patients.Thrombus or plague debris were found in 14 out of 26 retrieved filters(54%).There was no death or symptomatic cerebral thromboembolic event during the CAS procedure.Asymptomatic cerebral embolization lesions were detected in 3 patients by the means of diffusion-weighted magnetic resonance imaging after 1-6 days of the CAS.No major cerebral or cardiovascular ischemic events were recorded in all patients during their follow up period of 6-12 months.Conclusion Carotid artery stenting is an effective microinvasive therapy for severe carotid artery stenosis which effect and safety can be enhanced with the use of cerebral protection filter.
