OBJECTIVES: To evaluate the safety and feasibility of the use of covered stents for the treatment of extracranial carotid artery stenosis caused by highly embologenic plaques, and to study the long-term outcome of patients receiving such covered stents. METHODS: Between 2002 and 2007, 46 patients (63% symptomatic, 78.3% male, 67 +/- 8.6 years old) with internal carotid artery stenosis caused by embologenic plaques or restenosis were treated with self-expanding covered stents (Symbiot, Boston Scientific). Pre-dilatation or protecting devices were not used. Post-dilatation was applied in every patient. Each patient was followed long-term. The outcome measures were the occurrence of neurological events, and the development of in-stent restenosis, as detected by clinical examination and duplex ultrasound. RESULTS: The technical success rate of stenting was 100%. There were no neurological complications in the peri-procedural period. The mean follow-up period was 34.3 +/- 27.7 months (the rate of patients lost to follow-up was 15.2%) during which no stroke or stroke-related deaths occurred. Restenosis was detected in 3 patients (6.5%). CONCLUSION: Covered stents provide efficient peri- and post-procedural protection against neurological complications due to embolisation from high-risk plaques during carotid artery stenting. Restenosis of covered stents appears to be infrequent during long-term follow-up.
