Carotid stenting stenosis of the internal carotid artery. Carotid stenting may be considered an alternative to carotid surgery in average surgical risk patients, albeit with a higher risk of death or stroke as seen in the SAPPHIRE and CREST trials. Features that favor carotid stenting include non-atherosclerotic cause of the stenosis (fibrodysplasia, radiation, early post-surgical stenosis or flap) an experienced center and experienced physician performing the procedure. Features that make stent placement more difficult include significant aortic arch tortuosity, thrombus containing lesions, occluded carotid artery, heavily calcified vessels, symptomatic patients and very tortuous and twisting vessels. None of these affect open, surgical
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
