Leg vein thrombosis filters need to be removed.
During thrombolytic therapy after lower extremity venous embolism, emboli are easily dislodged and then flow into the heart and lungs with the blood circulation, blocking the blood vessels of the heart and lungs, resulting in acute cardiac infarction, pulmonary embolism and other acute and critical illnesses, which are life-threatening. Therefore, in order to prevent emboli from dislodging in advance, venous thrombosis filters of the lower extremity will be placed in order to intercept these dislodged emboli.
Lower extremity venous thrombus filters are usually removed 2 weeks after anticoagulation and thrombolysis, but some patients who do not retain the embolus and do not want to take it out for the time being need to use anticoagulant and antiplatelet aggregation drugs such as aspirin for a long period of time to prevent thrombosis, and the specific application of the program should be carried out under the guidance of the doctor.
