According to statistics, the first two-thirds of our brain blood comes from the carotid artery, when the intima thickens under certain factors (mainly atherosclerotic plaque) the lumen will become very narrow, resulting in the blockage of this important channel from the heart to the head, causing insufficient blood supply to the brain and even cerebral infarction, and 60% of the clinical cerebral infarction is due to carotid stenosis. The current treatment methods for carotid stenosis include medication and surgical treatment. Usually, if the patient has already experienced other symptoms of cerebral ischemia such as transient cerebral ischemia, blackout or cerebral infarction, and the stenosis exceeds 50%, surgical treatment is required; if the patient has not yet experienced symptoms such as dizziness and cerebral infarction, but the stenosis has exceeded 70%, active surgical treatment is also required; there is another condition with symptomatic stenosis: stenosis ≥ 50%, with a history of transient ischemic attack or cerebral infarction within six months to a year, need to receive surgery to improve symptoms as soon as possible. Can minimally invasive surgery be performed on carotid arteries? Carotid stenting is minimally invasive and can be considered in patients with severe cardiopulmonary disease who have difficulty tolerating general anesthesia; carotid stenosis due to radiation; carotid stenosis combined with skin damage to the neck; occlusion of the contralateral carotid artery; and high carotid bifurcation making the procedure difficult. It is also important to note that stent intervention may cause problems such as plaque dislodgement and restenosis, as well as the need for long-term postoperative medication, so it should be chosen with caution. In contrast, carotid endarterectomy is an ideal method to remove sclerotic plaque and prevent stroke. As the thickened intima and atherosclerotic plaque are removed, the blood supply to the brain is improved by unblocking the vessels, and the generation of emboli is also cut off. It has been proven to be an effective method for improving ischemic symptoms after numerous clinicopathological studies, and is also known as the gold standard for treating carotid stenosis. It is indicated for patients with lipid-rich soft plaques; plaques with a large range of diameters >15mm; intraplaque hemorrhage; and severely calcified plaques.
