ABSTRACT
Patient selection for carotid artery stenting (CAS) and clinical and technical experience are of key importance in achieving low complication rates. All cerebral protection devices are designed to safely capture and remove possible debris during the different procedural steps in order to prevent any embolization to the cerebral circulation. The principle of occluding the internal carotid artery (ICA) in between the lesion and the brain creates complete protection of the distal ICA and prevents emboli from migrating to the cerebral circulation. Debris is captured in an umbrella-like filter placed in the ICA between the lesion and the brain. After the CAS procedure, a specially designed retrieval device is advanced to a location immediately proximal to the filter for removal of the debris-filled device from the body. There are two different systems to deliver the filter distal to the lesion.
