The severity of atherosclerotic plaque formation in an unnamed artery is related to the size of the plaque. Small plaques are usually not serious, but large plaques are more serious. Smaller atheromatous plaques are generally not serious and can be controlled with prompt treatment, which will restore normal blood and oxygen supply to the arteries. However, in the case of large atheromatous plaques, they may detach on their own and easily form blood clots, which in severe cases will lead to insufficient blood and oxygen supply to the arteries, and cause plaque instability, and ultimately lead to occlusion. This situation is more serious and can be life-threatening if not treated in time. If plaque is found in the anonymous artery through examination, it is recommended to have a low-fat and light diet, go to the hospital for regular checkups, and also need to know whether there is a primary disease, and if necessary, give statins under the guidance of doctors to regulate lipid therapy.
