New ESO guideline released on endarterectomy and stenting for carotid artery stenosis

Based on moderate quality evidence, the authors recommend carotid endarterectomy (CEA) in patients with ≥60–99% asymptomatic carotid stenosis considered to be at increased risk of stroke on best medical treatment (BMT) alone. They also recommend CEA for patients with ≥70–99% symptomatic stenosis, and they suggest CEA for patients with 50–69% symptomatic stenosis. Based on high quality evidence, CEA should be performed early, ideally within two weeks of the last retinal or cerebral ischaemic event in patients with ≥50–99% symptomatic stenosis. Based on low quality evidence, carotid artery stenting (CAS) may be considered in patients < 70 years old with symptomatic ≥50–99% carotid stenosis. The results of another large trial comparing outcomes after CAS versus CEA in patients with asymptomatic stenosis are anticipated in the near future, that may influence treatment practices.
