In the current society, the economy is developing rapidly, and people’s living conditions are improving, whether it is food or travel, etc., all become more convenient. However, people’s health condition is gradually worrying, especially the incidence of carotid stenosis, a cerebrovascular disease, is gradually increasing, endangering people’s life and health safety, especially the middle-aged and elderly. The level of treatment for carotid stenosis varies from hospital to hospital, resulting in many patients with carotid stenosis not receiving good treatment, delaying the disease and even causing serious consequences such as cerebral infarction and neurological damage. Therefore, once you suffer from carotid stenosis, you should pay enough attention to find a regular hospital and receive the correct standardized treatment. Due to the relatively backward technical conditions in many local hospitals, carotid artery stenting is a relatively simple treatment for moderate to severe carotid artery stenosis. However, there are some problems with carotid artery stenting, such as the need for long-term medication to stabilize the plaque and prevent foreign body reactions; in addition, there is a relatively high chance of intravascular stent collapse, acute and chronic thrombosis, restenosis, occlusion, and stent fracture after surgery. Patients have asked what effective treatment options are available for restenosis after 80% stenting of carotid stenosis. Numerous comparative trials have shown that carotid endarterectomy has a better safety and treatment outcome than carotid stenting. The majority of carotid artery stenoses in Europe and the United States are treated with endarterectomy. In patients with restenosis after stenting, carotid endarterectomy can be used to remove the previously placed stent along with the intimal plaque, restore the carotid artery to its original size, restore blood flow, and remove the source of the embolus, thus effectively preventing the occurrence of cerebral infarction.
