The methods of thrombus elimination include intravenous thrombolysis, arterial thrombectomy, and antiplatelet and anticoagulant medication. Intravenous thrombolysis is suitable for patients with thrombus formation time within 4.5 hours, which can dissolve 30% of the thrombus and restore normal blood flow, and the commonly used intravenous thrombolytic drugs include alteplase and urokinase. Arterial thrombectomy is a minimally invasive procedure for patients whose thrombus formation time is less than 24 hours. It has an efficiency of more than 70% for the treatment of anterior cerebral circulation thrombosis, and is a very important approach to eliminate thrombus. For patients with prolonged thrombosis, antiplatelet agents or anticoagulant drugs can be chosen. Antiplatelet agents are indicated for non-cardiogenic thrombosis, and commonly used drugs include aspirin, clopidogrel hydrogen sulfate and cilostazol. Anticoagulants are indicated for patients with cardiogenic thrombosis and commonly used drugs include warfarin, rivaroxaban, and dabigatranate.
