Once a person gets sick, the desire for a better life is shattered. Everyone wants to be healthy for himself and his family, but some diseases visit suddenly and cause serious damage to the body. Carotid artery stenosis is one of the more frequent problems, and it is important to know that the carotid artery is a bridge between the heart and the brain, once the carotid artery is narrowed or even blocked, it is very dangerous. Carotid artery stenosis can be mild or severe, and patients with mild stenosis and no obvious symptoms can be controlled by taking medication. If the stenosis rate is too high, the condition is already very serious, and medication alone may not be very useful at this time, what is needed is timely surgery. In clinical practice, there are some patients who are hesitant to make a decision because they are worried about the risk of surgery, and as a result, the problem becomes more serious and more painful for themselves, which also adds much difficulty to the later treatment. We would like to remind you that the treatment of moderate to severe carotid stenosis needs to depend on the specific condition, and if necessary, take the surgical treatment. Although this method has certain effects, there are many defects and shortcomings. After surgery, the problem of embolus dislodgement can easily occur, and the formation of intra-stent thrombosis can lead to postoperative restenosis, requiring a second surgery, which is more painful and costly for patients. However, after continuous exploration and practice by experts in the medical field, a more advanced and effective method, namely carotid endarterectomy, has finally been introduced. This technique can directly peel off the thickened plaque and the diseased intima in the carotid artery area to restore the size of the carotid lumen and reestablish blood flow, and the postoperative recovery is ideal.
