Normally, permanent inferior vena cava filters are not removed, but they are surgically removed after they develop complications. In clinical practice, filters are placed to prevent the dislodgement of emboli from the inferior vena cava back into the pulmonary arteries leading to serious conditions such as pulmonary embolism. Permanent inferior vena cava filters can be left in the blood vessels for a long time without removal, but the filters are also a foreign body to the organism and can lead to serious complications secondary to thrombosis, so lifelong anticoagulation is required for this group of people. When complications occur, it is important to remove them in time through surgery so that the thrombus does not continue to develop, which in turn leads to vascular occlusion. With the development of modern medicine and new understanding, nowadays, temporary filters are mostly used in clinics to help patients get through the acute phase and then remove them, thus avoiding the complications associated with long-term filters.
