Abstract:
Objective To establish technique skills and evaluate complications of carotid artery stenting with the use of Filter. Methods In this study, 38 carotid lesions in 35 patients (with an asymptomatic stenosis exceeding 70% or a symptomatic stenosis exceeding 50% ) received stenting with the use of protective filter. The skills, complication and outcomes were evaluated. Follow-up surveillance included ultrasound examination, CTA, or MRA. Results The technique was successful in all 38 lesions. Angiography after stenting showed that the treated vessels were all patent (remained stenosis was less than 20% ). Sclerotic debris was found in 21 (55.3%) filters, 3 of which were full filled with debris. Complications included 1 (2.6%) stroke and hemiplegia, and I (2.6%) cerebral bleeding, 2 (5.3%) TIA after stenting and recovered after withdrawing the filter, 10 (26.3% ) suffered from perioperative transient decrease of heart rate and blood pressure. In a follow-up of 6 to 54 months (mean 32 months), all treated vessels were patent except 1 with stent-graft for carotid ulcer, no new TIA and stroke was found. Conclusion Meticulous technique and the use of carotid fiter permits carotid stenting in a safe and effective manner and prevents complications.
