Vascular plaques in the neck are commonly found in people who smoke, have high blood pressure and high blood lipids. The formation of this plaque is usually due to high blood lipids, which cause deposits under the intima and inflammatory reaction, bleeding and thrombosis, on the basis of which fibrosis and calcification gradually occur, forming the plaque of the neck vessels. This plaque will gradually increase in size with time and even narrow or occlude the lumen. Once the plaque appears, it should be taken seriously enough and strict cessation of smoking, including second-hand smoke, and strict control of blood lipids and blood pressure must be carried out.
