Carotid stenting Carotid stenting Carotid artery stenting (CAS) is an endovascular procedure where a stent is deployed within the lumen of the carotid artery to treat narrowing of the carotid artery and decrease the risk of stroke. CAS is used to treat narrowing of the carotid artery in high-risk patients, when carotid endarterectomy is considered too risky. Carotid artery stenosis can present with no symptoms or with symptoms such as transient ischemic attacks (TIAs) or strokes. The largest clinical trial to date, CREST, compared stenting to surgery on the collective incidence of any stroke, any heart attack or death. They found that
Carotid sinus therapeutic examination tool. In studies of thousands of uses on elderly patients, there were no complications of death or bradycardic events requiring treatment or resuscitation, even though this age group is more likely to be symptomatic from carotid sinus stimulation. A carotid massage can also possibly dislodge a thrombus, or some plaque. This could lead to any number of life-threatening effects, including stroke. Stimulation of the carotid sinus via a slap or a strike, to induce (usually temporary, but sometimes lethal) loss of consciousness is an effective self-defense technique, and is often taught in martial arts such as karate and
