The treatment of carotid intimal thickening with plaque formation is mainly through conservative treatment, such as anti-platelet aggregation drugs and statin lipid-regulating drugs, which aim to reduce platelet aggregation and inhibit lipids from entering the intima, and at the same time stabilize the plaque so that the soft plaque becomes hard plaque, which can prevent plaque rupture and lead to thrombosis or rupture leading to embolism of the distal artery, and then It is to reduce the inflammatory response of blood vessels, in short, to inhibit the further development of atherosclerosis. We should change our lifestyle, do not smoke, drink alcohol, eat fried food, fatty meat and animal offal, and eat a lighter diet with more vegetables and fruits. If the patient has diabetes, hypertension and hyperlipidemia, he or she needs to be actively controlled by medication, and the diet should be changed to a low-salt diet, low-sugar diet and low-fat diet, as well as proper exercise, preferably aerobic exercise, which can lower blood lipids and blood sugar and help in blood pressure control.
