Predictors of carotid occlusion intolerance during proximal protected carotid artery stenting.

Objectives: The aim of this study was to identify predictors of occlusion intolerance (OI) developing during proximal protected carotid artery stenting (CAS).

Background: The use of proximal embolic protection devices, such as endovascular occlusion, during CAS has been demonstrated to be particularly safe and effective. However, endovascular occlusion can expose the ipsilateral hemisphere to hypoperfusion and produce transient neurological symptoms (OI).

Proximal endovascular occlusion for carotid artery stenting: results from a prospective registry of 1,300 patients.

Objectives: This single-center registry presents the results of proximal endovascular occlusion (PEO) use in an unselected patient population.

Background: In published multicenter registries, the use of PEO for carotid artery stenting (CAS) has been demonstrated to be safe and efficient in patient populations selected for anatomical and/or clinical conditions.

Methods: From July 2004 to May 2009, 1,300 patients underwent CAS using PEO.
