Endarterectomy or Stenting in Severe Asymptomatic Carotid Stenosis.
2017
BACKGROUND: Stroke is a major cause of death in the western world, and carotid endarterectomy has been shown to be effective in treating both symptomatic and asymptomatic carotid stenosis. Carotid stenting is a relatively new form of treatment for carotid stenosis and few studies have looked specifically at asymptomatic patients. OBJECTIVES: To retrospectively examine short- and long-term results in the treatment of asymptomatic carotid artery stenosis with surgery or stenting. METHODS: We retrospectively collected data of all patients with asymptomatic carotid stenosis treated by carotid artery stenting or carotid endarterectomy in our department from 2006-2007. The primary endpoints were stroke, myocardial infarction, or death during the periprocedural period; or any ipsilateral stroke, restenosis, or death within 4 years after the procedure. RESULTS: The study comprised 409 patients who were treated by either stenting or surgery. There was a low morbidity rate in both treatment groups with no significant difference in morbidity or mortality between the treatment groups in both in the short-term as well as long-term. CONCLUSIONS: Both treatment methods have a low morbidity and mortality rate and should be considered for patients with few risk factors and a long life expectancy. Treatment method should be selected according to the patient's individual risk factors and imaging data.
