Abstract    Venous thromboembolism（VTE）is one of the most common fatal cardiovascular diseases in hospital.The application of inferior vena cava filter（IVCF）can greatly reduce the occurrence of fatal pulmonary embolism，however, long-term indwelling also brings related complications.An increasing number of guidelines recommend implanting physicians consider removing the filter as soon as protection from PE is no longer needed.However，the total retrievable rate of IVCF is not high due to the unbalanced development of clinical concept and technology.Most filters are eventually permanently placed，so how to reduce the complications of filters and greatly improve the removal rate of IVC filters?The author thinks that the following points should be done.1）clear indications of implantation，strict selection of standardized operation and precise implantation, 2）systematic monitoring of the filter during implantation，timely treatment of primary thrombosis and adequate anticoagulation, 3）effective treatment of IVCF thrombosis, standardized retrievable technology and effective use of various interventional technologies.
