Extracranial Carotid Stenosis
Recommendation
1- Stroke or TIA within previous 6 months with 70-99% carotid artery stenosis —> Carotid endarterectomy (Perioperative risk must be <6%)
2- Stroke or TIA with carotid artery stenosis —> Control BP, Lipid lowering drugs, Antiplatelet therapy
3- Stroke or TIA recently with 50-69% carotid stenosis —> Carotid endarterectomy should be considered according to individual’s features (Perioperative risk must be <6%)
4- CEA>CAS if age of patient ≥70 years
5- CEA>CAS if revascularization is scheduled within 1 week of index stroke
6- CAS>CEA if Severe stenosis accompanied with risk factors for surgery
7- CAS is an alternative to CEA if ICA stenosis is ≥70% and there is low risk of complications with endovascular approach
