1 Welcome to ACST-2! Guidance & Useful Information ACST-2 Office Level 6, Nuffield Department of Surgical Sciences University of Oxford, John Radcliffe Hospital Headley Way, Oxford OX3 9DU, UNITED KINGDOM

2 ACST-2: Asymptomatic Carotid Surgery Trial –2 ACST-2 compares carotid endarterectomy and carotid stenting in patients with tight asymptomatic carotid stenosis carotid surgery (CEA) or carotid stenting (CAS) Primary outcomes to compare:- 1) peri-procedural risks (MI, stroke & death) within 30 days after allocated intervention (CEA or CAS) 2) compare long term benefits of stenting and surgery

3 ACST-2 Background First patient randomised: 15/01/2008 Patients are now in their 6 th year of follow up 92 active centres from 27 countries Largest (investigator-led) trial in the world comparing surgery vs. stenting in asymptomatic patients, having recruited >1,520 Goal: recruit over 3,600 patients by the end of 2019 Currently the peri-procedural stroke (fatal and disabling) and death within 30 days is 1.0 % in 1078 patients

4 Clinician Duplex Doppler CTA MRA Patient consent and entering in trial DETECTION Patient eligibility discussed (e.g. MDT ) TIA/stroke clinics Stroke inpatients Vascular outpatients Screening Cardiology or cardiothoracic surgery assessment WHERE WE FIND TRIAL PATIENTS

5 Know the Inclusion Criteria Tight carotid artery stenosis (>70%), confirmed by duplex ultrasound MRA/CTA shows that CEA and CAS are both practicable No symptoms or signs* on the IPSILATERAL side for at least 6 months Patient is still eligible even if they’ve had a symptom or sign* on the CONTRALATERAL side within 6 months Doctor & patient are uncertain about whether to treat with CEA or CAS, but are certain an intervention is needed Patient is fit and willing for follow- up and is likely to live 5 to 10 years (*MR/CT infarcts)
