Carotid artery stenting (CAS) has been developed in recent years as an alternative to carotid endarterectomy (CEA). We report our clinical experience of CAS and evaluate the feasibility and efficacy of this treatment. Since 1997 Feb, 237 patients (199 male, aged 50-85, mean 67.5), 235 carotid artery stenosis (109 symptomatic, 126 asymptomatic), 5 aortitis, 1 FMD, and 6 dissecting were treated with 259 endovascular stenting procedures. Our method in now is as follows;under local anesthesia, transfemoral approach, using guiding catheter, pre-dilation with low profile 3mm PTA balloon with. 014" long wire, and self-expandable stent deployment. Since 1998 Dec, we have used our originally made distal balloon protective system in post PTA. Procedural success was 99.2%, and complications occurred in 2 (0.77%) major and 6 (2.3%) minor stroke without mortality. Restenosis occurred in 12/155 (7.7%) of F/U angiography, 6-50 months after treatment. No complication occurred in re-treatment. Our results indicate that carotid stenting may well offer a similar safety profile and efficacy to those of carotid endarterectomy. The future status of carotid artery stenting will be determined with randomized trials and improvement in devices, technique and safety.
