Early experience of carotid artery stenting with distal filtration device--4 cases report / 中国介入心脏病学杂志

ABSTRACT

Objective The purpose of this study was to assess the effectiveness and safety of distal filtration protection devices during carotid artery stenting.Methods Between June and July in 2002, carotid artery stenting (CAS) were performed in 4 patients with asymptomatic severe carotid artery stenosis. Self-expendable stents (Smart, Cordis) and distal filtration devices (Angioguard XP, Cordis) were used in all patients. Primary endpoints were perioperative neurologic complications and mortality. Data were collected prospectively.Results All patients were male, their age were 59?4 years old. One patient had history of transient ischemic attacks(TIAs); and another had inferior myocardial infarction, and right coronary intervention was performed before CAS, and another one underwent CABG 6 months ago. There were two right internal carotid and two left internal carotid severe lesions (82.5?6.0)% were treated. The filtration devices and stents were delivered and deployed successfully in all target artery (technical success rate was 100%) and
