Vascular blockage specific selection of what drugs are effective, need to be based on the cause and condition of the decision, such as cerebral infarction selection of edaravone, myocardial infarction selection of aspirin, lower extremity deep vein thrombosis selection of low molecular heparin, pulmonary embolism selection of urokinase and so on. 1. Cerebral infarction: it is mainly caused by atherosclerosis of cerebral arteries which leads to blood vessel blockage, resulting in blood circulation disorder in the brain and ischemia and hypoxia of tissues; those with mild symptoms can choose edaravone and cytidine neuroprotective drugs for treatment, and those with severe symptoms can choose thrombolytic drugs such as urokinase for treatment, and if necessary, perform surgical treatment. 2. Myocardial infarction: it is mainly caused by atherosclerosis of coronary arteries, which leads to the blockage of blood vessels, resulting in myocardial ischemia and hypoxia; in the stable period, it can be treated with aspirin against platelet aggregation, atorvastatin or reseruvastatin for lipid regulation, and in the acute attack period, it can be treated with aspirin, clopidogrel and other drugs for double combination of antiplatelet aggregation, and coronary stenting can be carried out if necessary. 3. Lower extremity deep vein thrombosis: due to infection, autoimmune abnormalities and other factors, resulting in blood coagulation in the lower extremity deep vein system, resulting in vascular occlusion; embolism can be selected for mild anticoagulation with low molecular heparin, and embolism can be selected for more serious thrombolytic treatment with urokinase, and surgical treatment if necessary. 4. Pulmonary embolism: it is mainly the embolus of the deep veins of the lower limbs, which enters into the lungs along with the blood circulation system, thus leading to the blockage of the pulmonary artery or the branch of the blood vessels; usually, those with mild condition can choose anticoagulant drugs such as warfarin and rivaroxaban, and those with more serious embolism need to choose thrombolytic drugs such as urokinase and streptokinase, or perform surgical thrombolysis treatment. When the above symptoms occur, it is recommended to go to the hospital in time, early standardized treatment, the above drugs should be used under the guidance of the doctor.
