About this trial

Carotid stenosis caused by atherosclerosis is a significant risk factor for ischemic stroke, accounting for up to 15% of all strokes and transient ischemic attacks. Randomized clinical trials (RCTs) have demonstrated the benefits of carotid endarterectomy (CEA) in reducing stroke risk in patients with severe symptomatic carotid stenosis. Carotid artery stenting (CAS) has been developed as an alternative to CEA, offering several potential advantages, such as avoiding local surgical complications. However, unlike CEA, CAS has not been compared to medical therapy in RCTs for symptomatic carotid stenosis.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patient age 18 years or over

Hemispheric or retinal transient ischemic attack or a non-disabling stroke (or retinal infarct) within 15 days before enrolment

Stenosis of 50% to 99% in the symptomatic carotid artery (NASCET method) for whom revascularisation is decided according to guidelines

Disqualifiers

Patients unwilling or unable to participate in follow-up for whatever reason

Preexisting disability (Modified Rankin Score ≥ 3)

Nonatherosclerotic carotid disease

Severe tandem lesions

Trial design

Design model

Parallel

Treatments tested in this trial

  • carotid endarterectomy

    Procedure/Surgery

    Carotid endarterectomy is a surgical procedure used to reduce the risk of stroke due to carotid artery stenosis. During an endarterectomy, the surgeon opens the artery and removes the plaque.

  • Carotid artery stenting

    Procedure/Surgery

    Carotid artery stenting is an endovascular procedure in which a stent is deployed in the lumen of the carotid artery to treat narrowing of the carotid artery and reduce the risk of stroke.

Treatment groups

Trial outcomes

Primary outcomes

1

DWI Lesion Detection Rate

Imaging endpoint : Proportion of patients having at least one new lesion on post-treatment Diffusion-Weigthed Imaging (DWI) MRI compared to pre-treatment DWI MRI and confirmed by a core lab. The pre-treatment DWI MRI will be performed within 3 days before procedure. The post-treatment DWI MRI will be performed within 7 days after procedure.

Time frame
From 3 days before procedure to 7 days after procedure

Secondary outcomes

1

Profile of lesions

Imaging endpoint : Number and size of new lesions on post-treatment MRI. The pre-treatment DWI MRI will be performed within 3 days before procedure. The post-treatment DWI MRI will be performed within 7 days after procedure.

Time frame
From 3 days before procedure to 7 days after procedure
2

Vessel Occlusion Profile

Imaging endpoint : Proportion of patients having a new intracranial vessel occlusion on post-treatment MRI. The pre-treatment DWI MRI will be performed within 3 days before procedure. The post-treatment DWI MRI will be performed within 7 days after procedure.

Time frame
From 3 days before procedure to 7 days after procedure
3

Hemorrhage

Imaging endpoint : Hemorrhagic transformation on post-treatment MRI. The pre-treatment DWI MRI will be performed within 3 days before procedure. The post-treatment DWI MRI will be performed within 7 days after procedure.

Time frame
From 3 days before procedure to 7 days after procedure
4

Stroke/Mortality

Clinical endpoint : proportion of patients having any stroke or death during periprocedural period.

Time frame
From randomization to 30 days after procedure
