Carotid angioplasty and stenting (CAS) is not safer than carotid endarterectomy (CEA) for symptomatic stenosis. CAS may suit high-risk patients, but more research is needed to identify optimal candidates for carotid revascularization.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Neurology

Background:

  • Carotid stenosis poses a significant risk of stroke.
  • Carotid endarterectomy (CEA) is the established treatment.
  • Carotid angioplasty and stenting (CAS) is an emerging alternative.

Purpose of the Study:

  • To review the evidence comparing CAS and CEA for carotid stenosis.
  • To determine if CAS offers advantages over CEA.
  • To identify patient subgroups that may benefit from CAS.

Main Methods:

  • Systematic review of existing literature.
  • Analysis of randomized controlled trials and registries.
  • Comparison of safety and efficacy outcomes between CAS and CEA.

Main Results:

  • CAS is not safer and does not offer better short-term outcomes than CEA in non-high-risk symptomatic patients.
  • Evidence for CAS in asymptomatic patients suitable for CEA is insufficient.
  • CAS may be suitable for high-risk patients, but definitions of high risk vary, and comparative data is limited.

Conclusions:

  • CEA remains the gold standard for eligible patients with carotid stenosis.
  • CAS is a potential option for selected patients, particularly those at high surgical risk.
  • Further research is required to define optimal patient selection for CAS versus CEA.
