Carotid artery stenting offers minimal benefit for asymptomatic patients and may be harmful. For symptomatic patients, carotid stenting can cause emboli, highlighting risks in current practice.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Neurology

Context:

  • Carotid artery stenting (CAS) is increasingly performed, but its efficacy and safety are debated.
  • Current practice often includes patients with asymptomatic carotid lesions or suboptimal stenosis degrees.
  • Concerns exist regarding patient selection and the applicability of trial results to community hospitals.

Purpose:

  • To critically analyze recent publications on carotid artery stenting.
  • To evaluate the appropriateness of patient selection in modern CAS series.
  • To assess the risks and benefits of CAS in both asymptomatic and symptomatic carotid stenosis.

Summary:

  • CAS for asymptomatic carotid lesions provides marginal benefit and carries risks, including infra-clinical cerebral micro-infarcts.

Related Experiment Videos

  • Many current CAS series include patients with stenosis below the optimal NASCET range (70-99%).
  • The EVA-3S trial was halted due to high cerebral morbidity in the stenting group, and CAS for symptomatic lesions can generate emboli.

    • Impact:

    • Highlights the potential futility and harm of CAS in asymptomatic patients.
    • Questions the current indications and patient selection criteria for CAS.
    • Underscores the need for careful consideration of risks versus benefits in CAS procedures, particularly regarding cerebral micro-infarcts and emboli.
