Summary
Carotid angioplasty and stenting offer a minimally invasive option for stroke prevention, comparable to carotid endarterectomy. Ongoing trials focus on cerebral protection devices to mitigate risks associated with stenting.
Area of Science:
- Vascular Surgery
- Interventional Neurology
- Cerebrovascular Disease
Background:
- Carotid endarterectomy is the traditional treatment for carotid occlusive disease and stroke prevention.
- Endovascular techniques, including carotid angioplasty and stenting, have emerged as alternatives.
- Cerebral embolization and subsequent neurologic complications are potential risks of carotid stenting.
Purpose of the Study:
- To review the current status of carotid artery stenting (CAS) in treating carotid occlusive disease.
- To discuss recent clinical studies and ongoing prospective trials evaluating CAS efficacy.
- To explore strategies for cerebral embolization protection during CAS.
Main Methods:
- Review of current literature on carotid angioplasty and stenting.
- Analysis of data from recent clinical studies comparing CAS and carotid endarterectomy.
- Discussion of cerebral protection devices and ongoing prospective trials.
Main Results:
- Current data suggest similar success and complication rates between CAS and carotid endarterectomy.
- Cerebral embolization remains a concern, driving research into protective measures.
- Numerous prospective trials are investigating the efficacy of CAS with various cerebral protection devices.
Conclusions:
- Carotid artery stenting is a viable therapeutic option for carotid occlusive disease.
- Further research, particularly through prospective trials focusing on cerebral protection, is crucial.
- Optimizing safety through effective embolization prevention strategies is key to widespread CAS adoption.
