Causes of leg blood vessel blockage include lower extremity arterial thromboembolism, lower extremity atherosclerosis, and deep vein thrombosis. Leg blood vessel blockage can be treated by medication, surgery and other ways. 1. Lower extremity arterial thromboembolism: Atrial fibrillation, rheumatic heart disease, atherosclerosis and other patients in the body after the embolus fall off with the blood circulation caused by the leg blood vessel blockage, which leads to lower extremity arterial thromboembolism. You can take aspirin and other antiplatelet drugs under the guidance of a doctor, or arteriotomy to remove the thrombus and other treatments for blocked blood vessels in the legs. 2. Atherosclerosis of the lower limbs: This refers to the formation of different degrees of plaque in the arteries of the lower limbs, resulting in narrowing of the lumen of the blood vessels, which can lead to blockage of the blood vessels in the legs in severe cases. It can be treated with arterial bypass surgery, angioplasty, etc. as recommended by the doctor. 3. Deep vein thrombosis: When the patient’s blood flow is slow and the blood is in a high coagulation state, it is easy to lead to deep vein thrombosis, thus blocking the blood vessels in the legs. You can take anticoagulant drugs such as warfarin under doctor’s guidance, or have lower vena cava filter implantation according to doctor’s suggestion. Since the causes of leg blood vessel blockage and the degree of the disease are different, the treatment methods are also different, so we should consult the doctor in time to clarify the cause of the disease and carry out standardized treatment under the doctor’s guidance.
