Carotid endarterectomy (CEA) shows lower peri-procedural stroke risk than carotid artery stenting (CAS). CAS is safer for younger patients, while CEA is preferred for elderly individuals regarding stroke risk.

Area of Science:

  • Vascular Surgery
  • Neurology
  • Interventional Cardiology

Background:

  • Internal carotid artery stenosis is a significant cause of ischemic stroke.
  • Carotid endarterectomy (CEA) is a proven stroke risk reduction therapy.
  • Carotid artery stenting (CAS) offers an endovascular alternative to CEA.

Purpose of the Study:

  • To review and compare the risks and benefits of CAS versus CEA.
  • To focus on evidence derived from randomized clinical trials.
  • To assess the safety and efficacy of CAS as an alternative to CEA.

Main Methods:

  • Systematic review of randomized clinical trials comparing CAS and CEA.
  • Analysis of peri-procedural complications and long-term outcomes.
  • Stratification of results based on patient age and symptomatic status.

Main Results:

  • CEA demonstrated a lower risk of peri-procedural stroke or death compared to CAS.
  • CAS was associated with reduced risks of myocardial infarction, cranial nerve palsy, and access site hematoma.
  • CAS is a potentially safer option for younger patients, whereas elderly patients face higher stroke risks with CAS.

Conclusions:

  • CEA has a lower peri-procedural stroke risk than CAS.
  • CAS offers specific advantages in reducing certain complications, particularly in younger patient populations.
  • Long-term effectiveness and optimal treatment for asymptomatic stenosis require further investigation through ongoing trials.
