People always say that the carotid artery is the lifeline of the body, why? It is because the blood from the heart is mainly delivered to the head, face and neck through the carotid artery. If a problem occurs in the carotid artery, the consequences can be very serious. Nowadays, carotid artery stenosis is a highly prevalent cerebrovascular disease, and carotid artery stenosis does not supply blood properly, so health problems occur frequently and must be actively treated and controlled. The treatment of carotid artery depends on the situation. Mild carotid artery stenosis is mainly treated with conservative medication, which aims to control the growth of plaque, prevent further stenosis, and stabilize the plaque to prevent it from falling off and causing cerebral infarction. If the carotid stenosis is more than seventy percent, surgical treatment is needed to better treat and reduce the damage. The current surgical option for carotid stenosis is carotid endarterectomy, a procedure that can effectively prevent brain infarction and stroke caused by carotid stenosis. What are the risks of carotid endarterectomy? In fact, carotid endarterectomy has been used for a long time and is technically very mature, and there are many successful cases. Patients who are concerned about the safety of carotid endarterectomy can learn that carotid endarterectomy is performed under direct microscopic vision and the risks of the procedure are minimal. This technique can successfully remove the diseased intimal plaque and restore the smooth inner wall and normal inner diameter of the carotid artery, which greatly improves the patient’s cerebral blood supply and effectively prevents cerebral infarction.
