If a localized thrombus causes a narrowing of a blood vessel but not yet a blockage, anticoagulants, antiplatelet agents, and lipid-regulating drugs can be used to prevent the progression of the thrombus and to slowly disintegrate it. Once the thrombus has caused the blockage of blood vessels, especially the blockage of blood vessels of important organs and tissues, thrombolytic therapy must be carried out as soon as possible. 1. Anticoagulants: Heparin and warfarin are commonly used, because the effect of warfarin takes 3 to 4 days, so in the acute stage, heparin is usually used intravenously or subcutaneously, and then warfarin is taken orally. 2. Antiplatelet drugs: commonly used aspirin, clopidogrel, tegretol and so on. They can inhibit the aggregation of platelets and prevent the thrombus from increasing in size. 3. Lipid-regulating drugs: Atorvastatin, Rosuvastatin, etc. are commonly used. They can not only regulate blood lipids, improve blood flow rate and prevent the progress of thrombus, but also prevent and control atherosclerosis and prevent the formation of new thrombus. 4. Thrombolytic drugs: commonly used are urokinase, streptokinase, alteplase. They can dissolve the thrombus, restore blood flow to the blocked blood vessels, and reduce ischemic injury of the body. When thrombosis is found, it is recommended to consult a doctor in time, do not delay the time, so as not to miss the best time for treatment.
