Study Summary
The goal of the proposed study is to contrast the relative efficacy of closed-cell stents versus open-cell stents in preventing periprocedural cerebral embolization in high-risk patients with symptomatic and asymptomatic extracranial carotid stenosis undergoing carotid artery stenting (CAS).
Primary Outcome
Bilateral transcranial Doppler scan monitoring of the anterior and middle cerebral arteries was performed using a PMD150-ST3 digital transcranial Doppler pulsed-wave ultrasound scan system (Spencer Technologies, Seattle, Wash) with 2-MHz probes located over the temporal bones above the zygomatic arch. Isolated microembolic signals (MES) were identified from Doppler spectras according to the criteria given by the Consensus Committee of the Ninth International Cerebral Hemodynamic Symposium. If th
Interventions
- DEVICE closed-cell stent (Xact stent)
- DEVICE Open-cell stent (Acculink carotid)
