Bilateral common iliac arteries and their branches have atherosclerosis, meaning that there should be atherosclerotic plaque formation in the common iliac arteries and branches, this condition is usually a decrease in the elasticity of the blood vessels, the lumen of the blood vessels is narrowed due to atherosclerotic plaque, and when the stenosis is severe the blood flow of the blood vessels is affected, and ischemia of tissues will occur. The common iliac artery and branch vessels, which are the arterial blood supply vessels of the abdominal cavity and lower extremities, have atherosclerosis, meaning that there is atherosclerotic plaque formation, which is the result of cholesterol-lipid plaque deposition in the arterial wall, if the plaque is small and the stenosis is less than 50%, it usually does not affect the blood flow, and if the stenosis is more than 50%, for example, up to 90%, it may even require surgical treatment. Atherosclerotic plaque formation is found, need to formalize to vascular surgery or cardiology consultation, need to control blood lipids, etc., take atorvastatin drugs on time and pay attention to a healthy lifestyle to prevent the development of atherosclerotic plaque aggravation. Drugs need to be used under the guidance of a doctor, avoid self-medication.
