Carotid stenting there was no significant differences out to four years of follow-up between surgery and carotid stenting when counting all three, but carotid endarterectomy (CEA) has a higher risk of heart attacks and CAS has a higher risk of minor stroke than open surgery. Overall, younger patients (<70 years old) had better outcomes with stenting than with surgery. Patients had fewer heart attacks with stenting, but they did have more minor strokes. There was no difference between surgery or stenting for major (disabling) strokes. Prior to this, several European trials have reported results in symptomatic carotid artery stenosis patients comparing surgery
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
