Summary
Carotid artery stenting (CAS) is not superior to carotid artery endarterectomy (CEA) in major trials. A literature review found CAS has higher risks and costs, questioning its widespread use.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Neurology
Background:
- Carotid artery stenting (CAS) and carotid artery endarterectomy (CEA) are procedures to prevent stroke.
- Recent trials (EVA-3S, SPACE, ICSS, CREST) have compared these treatments.
Purpose of the Study:
- To evaluate the current evidence comparing CAS and CEA.
- To address the ongoing debate regarding the role of CAS in managing carotid artery disease.
Main Methods:
- Comprehensive literature search of contemporary published studies on carotid artery stenting.
- Analysis of data from key randomized controlled trials comparing CAS and CEA.
Main Results:
- Four major trials found no superiority of CAS over CEA.
- CAS is associated with a higher peri-procedural stroke-death rate and increased costs.
- CAS also shows a higher rate of late restenosis and increased risk of micro-embolization compared to CEA.
Conclusions:
- There is currently no Level-I evidence supporting the routine use of CAS.
- The benefits of CAS do not justify the prevailing enthusiasm among interventionalists.
- CEA remains a preferred treatment option based on current evidence.
