title: Surgery in asymptomatic carotid stenosis: no advantage.
abstract: A meta-analysis of three trials including a total of about 5000 patients showed no reduction in mortality after surgery for asymptomatic carotid stenosis. The risk of vascular ischaemic events increased by about 3% during the first month, then decreased by about 1% per year for 3 to 4 years.
