Summary

Carotid angioplasty and stenting (CAS) shows improved stroke rates, potentially nearing carotid endarterectomy (CEA) outcomes. However, CAS is recommended only for specific cases, with medical therapy preferred for asymptomatic patients.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Neurology

Background:

  • Endovascular therapies are increasingly utilized across various vascular applications.
  • The efficacy and safety of carotid angioplasty and stenting (CAS) compared to carotid endarterectomy (CEA) remain under investigation.
  • Initial CAS outcomes demonstrated higher stroke morbidity than CEA, failing to meet established guidelines.

Purpose of the Study:

  • To evaluate the evolving role and safety of carotid angioplasty and stenting (CAS) in managing carotid artery disease.
  • To compare the stroke morbidity and mortality rates of CAS with embolic protection devices against carotid endarterectomy (CEA).

Main Methods:

  • Ongoing randomized clinical trials are comparing CAS with embolic protection to CEA.
  • Analysis of recent improvements in CAS, including the impact of embolic protection devices.

Main Results:

  • Recent advancements have led to improved stroke morbidity rates with CAS, potentially approaching CEA levels.
  • Embolic protection devices have reduced embolic complications associated with CAS, though their long-term impact requires further study.
  • Initial comparative studies indicated unacceptably high stroke morbidity in the CAS group.

Conclusions:

  • CAS is advocated as an adjunct to CEA for select patients unsuitable for surgery.
  • Medical therapy remains the primary recommendation for asymptomatic patients with carotid artery disease due to CAS stroke risk exceeding guidelines.
  • Further data from ongoing trials are crucial to definitively establish the role of CAS in stroke prevention.
