Whether a carotid plaque requires treatment is determined not only by its size, but also by the severity of the stenosis and accompanying clinical symptoms. Usually, if the carotid plaque is large enough to cause a stenosis of more than 70%, surgical treatment is required, which usually involves removal of the carotid artery lining. Surgery is also needed if the stenosis is more than 50 percent and is accompanied by symptoms such as dizziness. When the plaque in the carotid artery is non-calcified and unstable, in order to avoid rupture and bleeding, it can be treated with oral medications such as Rosuvastatin and aspirin. The use of drugs should be under the guidance of a doctor, and also pay attention to maintain a healthy lifestyle, diet should be kept low in salt and fat, but also moderate exercise. Therefore, carotid plaques with a stenosis of more than 50% and accompanying symptoms, or with a stenosis of more than 70%, as well as unstable plaques, require treatment.
