Carotid stenting with the use of wallstent.

Cerebral infarction is a known potential risk associated with implanting a stent in a carotid artery.
It can be defined as an area of necrotic tissue in the brain resulting from a blockage or narrowing in the arteries supplying blood and oxygen to the brain.
The act of stent expansion or post-dilatation, to optimally oppose a carotid stent to the vessel wall, temporarily obstructs blood flow to the cerebral arteries (ischemic process).
The physical manipulation of the carotid arteries produces the risk of dislodgement of debris that may travel upstream to the cerebral arteries potentially disrupting perfusion.
This act, inherent to the procedure may have contributed to the reported event.
The blocked or narrowed arteries deprive brain cells of oxygen and nutrients, leading to nerve cell death.
Early medical intervention can halt this process and reduce the risk for irreversible complications.
Review of the information suggests that patient, vessel and procedural factors may have contributed to the reported events.
There is no indication that the event is related to the device design or manufacturing process.
Therefore, no preventative or corrective actions will be taken at this time.
