Recruitment is now closed!
Follow up will be continuing for the future. We look forward to having the first results in ACST-2 later this year (2021)
Message from the Chief Investigators
Patients in ACST-2 have tight asymptomatic carotid stenosis. We are comparing both the immediate hazards of the procedures when carried out by experienced doctors and the subsequent stroke rates over the next 5 to 10 years.
