Insights
Carotid endarterectomy (CEA) is crucial for preventing stroke in patients with significant carotid artery stenosis. Patch closure during CEA reduces restenosis, while carotid angioplasty and stenting (CAS) offers a less invasive alternative.
Area of Science:
- Vascular Surgery
- Neurology
- Cardiovascular Medicine
Background:
- Stroke is a leading cause of death, with carotid occlusive disease causing up to one-third of strokes.
- Carotid endarterectomy (CEA) is a key surgical treatment for carotid artery stenosis.
- Patient selection for CEA is guided by stenosis severity and symptomatic status.
Purpose of the Study:
- To review the established indications for carotid endarterectomy (CEA).
- To discuss the controversial timing of CEA post-stroke.
- To evaluate different methods of arteriotomy closure and alternative surgical techniques.
Main Methods:
- Review of prospective randomized trials defining patient selection criteria for CEA.
- Analysis of studies comparing primary arteriotomy repair versus patch closure.
- Comparison of standard CEA with carotid eversion endarterectomy (CEE) and carotid angioplasty and stenting (CAS).
Main Results:
- CEA is indicated for asymptomatic patients with >= 60% stenosis and symptomatic patients with >= 50% stenosis.
- Patch closure of the arteriotomy reduces the rate of restenosis compared to primary repair.
- Carotid eversion endarterectomy (CEE) demonstrates similar efficacy to standard CEA.
Conclusions:
- Early CEA may benefit select patients following a stroke.
- Patch closure is superior to primary repair for reducing restenosis after CEA.
- Carotid angioplasty and stenting (CAS) presents an evolving, less invasive treatment option for carotid plaque.
Abstract:
Stroke is the third leading cause of death in the United States, and up to one third of patients have a stroke secondary to carotid occlusive disease. Surgical management has firmly established itself as an important modality in treating this disease. Several prospective randomized trials have defined the patients that would have the most benefit from carotid endarterectomy (CEA). These patient populations include asymptomatic patients with a >or= 60% stenosis and symptomatic patients with a >or= 50% stenosis. The timing of CEA after stroke remains controversial, but recent studies advocate early CEA in a select group of patients. During the CEA, the method of closing of the arteriotomy has an overall effect on the safety of the procedure as well as long-term outcome. As compared with primary repair of the arteriotomy, patch closure has been shown to decrease the frequency of restenosis. In addition, carotid eversion endarterectomy (CEE) is an alternative method to remove the plaque that has a similar efficacy to standard CEA. The role of carotid angioplasty and stenting (CAS) continues to evolve and offers the patient a less invasive method of treating the carotid plaque.
