Comparison of Anti- Embolic Protection with Proximal Balloon Occlusion and Filter Devices During Carotid Artery Stenting: Clinical and Procedural Outcomes

High-Risk Factors in Symptomatic Patients Undergoing Carotid Artery Stenting With Distal Protection

“…In a recent randomized controlled trial comparing CAS with proximal vs distal protection devices, although there was no difference in the overall complication rate, proximal protection was associated with lower rates of ICA vasospasm. 63 In another study, proximal protection was associated with fewer postprocedural diffusion-weighted imaging lesions compared with distal protection. 64 Understandably, the use of proximal protection devices instead of distal protection filters will also eliminate the concern about a poor distal landing zone in certain patients, which was shown in our study to be a significant risk factor for poor outcome after CAS.…”
