Overview
For people with a greater than 70% stenosis within the carotid artery, removal of atherosclerotic plaque by surgery, specifically a carotid endarterectomy, may be recommended.
Surgery
Carotid Endartectomy
Carotid endartectomy may be performed within 2 weeks of cerebral or retinal TIA in those with TIA attributed to a high-grade internal carotid artery stenosis:[1][2][3]
| Degree of carotid artery stenosis | Carotid endartectomy |
|---|---|
| 70-99% internal carotid artery stenosis | Recommended |
| 50-69% stenosis | Recommended only in specific situation† |
| <50% stenosis | Not recommended |
Extracranial-Intracranial Bypass
Extracranial-intracranial bypass is not recommended in patients with TIA.[1]
†Recommended only in certain patients and at centres with perioperative complication rate of <6%
