Carotid Artery Stenting-Historical Context, Trends, and Innovations

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Neurology

Background:

• Carotid endarterectomy (CEA) was the standard for severe carotid artery disease.
• Carotid artery stenting (CAS) was initially for high-risk patients due to technical challenges.
• Both procedures aim for primary and secondary stroke prevention.

Purpose of the Study:

• To review the historical development of carotid artery stenting (CAS).
• To discuss current trends and innovations in CAS.
• To position CAS as an alternative to CEA.

Main Methods:

• Literature review focusing on historical data.
• Analysis of trends in CAS adoption and outcomes.
• Examination of technological innovations in CAS devices and techniques.

Main Results:

• CAS has evolved from a high-risk procedure to a reliable alternative to CEA.
• Technological advancements have improved CAS safety and efficacy.
• CAS is increasingly considered for a broader patient population.

Conclusions:

• CAS is a viable and evolving treatment option for severe carotid artery disease.
• Innovations continue to enhance the role of CAS in stroke prevention.
• The choice between CAS and CEA depends on patient-specific factors and evolving evidence.
