This study aims to review retrospectively the records of patients treated with carotid artery stenting (CAS) to investigate the potential correlations between clinical variables, distal protection filter (DPF) type and characteristics, and 30-day peri-/postprocedural outcomes.
They found the following features were important to minimise adverse events:
Higher vascular resistance, concentric in shape, greater capture efficiency, lower porosity, lower number of pores, and lower pore density. Lower porosity and smaller wall apposition were also found to be independently significant for minimization of peri-/postprocedural TIAs

The Protected Carotid Artery Stenting in Patients at High Risk for Carotid Endarterectomy (PROTECT) study was performed to evaluate the safety and effectiveness of two devices for carotid artery stenting (CAS) in the treatment of carotid artery stenosis in patients at high risk for carotid endarterectomy (CEA): (1) a new embolic protection device, the Emboshield Pro (Abbott Vascular, Abbott Park, Ill), using the periprocedural composite end point of 30-day death, stroke, and myocardial infarction (DSMI), and (2) a carotid stent in conjunction with an embolic protection device (EPD) using the DSMI periprocedural composite end point plus ipsilateral stroke at up to 3 years for long-term evaluation.

The aim of this study was to examine the incidence of ischemia during protected carotid artery stenting (CAS) as well as to compare the protective efficacy of the balloon and filter devices on diffusion-weighted MR imaging (DWI).

This paper discusses an alternative to filter devices to reduce cerebral embolic events during carotid stenting.
Conclusion: Use of the reverse flow device was associated with fewer overall lesions on DWI and proportionately fewer positive scans compared with the use of filter-type devices (P = .08, not significant). Transcranial Doppler recordings demonstrated a significant reduction in embolization to the brain during carotid artery stent placement with the use of reverse-flow cerebral protection.
