What does this research mean for the field?

Carotid endarterectomy provides proven clinical benefit for symptomatic patients with 70% or greater carotid stenosis when performed by surgeons with low perioperative morbidity and mortality, but is inappropriate for patients with stenosis under 50%. Novelty: ClaimNovelty.SYNTHESIS. Consensus alignment: ConsensusAlignment.SUPPORTS_CONSENSUS.

What question did this study set out to answer?

Why the study?

Indications for carotid endarterectomy have been debated extensively, resulting in diverse publications and a need for multidisciplinary consensus guidelines.

What are the appropriate indications for carotid endarterectomy in patients with carotid artery disease?

Key Points

Establish evidence-based consensus guidelines defining appropriate indications for carotid endarterectomy across symptomatic and asymptomatic patient groups based on surgical risk and degree of stenosis.
Convened an American Heart Association consensus conference in July 1993 with specialists in neurology, neurosurgery, vascular surgery, and healthcare planning.
Evaluated natural history studies, community audits, and randomized clinical trials to classify 96 potential surgical indications into four categories: proven, acceptable but not proven, uncertain, and proven inappropriate.
Carotid endarterectomy is proven beneficial for symptomatic patients with ≥70% stenosis and recent transient ischemic attack or mild stroke when performed by surgeons with <6% perioperative morbidity and mortality.
Surgery is acceptable but not proven for symptomatic patients with 50% to 69% stenosis and for asymptomatic patients with >75% diameter stenosis when surgeon morbidity and mortality is <3%.
Interventions are proven inappropriate for symptomatic patients with <50% stenosis not on aspirin or whenever expected combined surgical stroke morbidity and mortality exceeds 5%.
