ObjectiveTo explore the value of recombinant inferior vena cava filter (IVCF) in the prevention of perioperative pulmonary embolism in patients with lower limb or pelvic fracture combined with deep venous thrombosis (DVT).MethodsThe clinical data of 168 patients with lower limb or pelvic fracture combined with DVT were analyzed retrospectively.ResultsThe filters were successfully implanted in 168 patients, and the recoverable filters were removed after (48.3±4.8) d (14–97 d). The filters were removed successfully in 159 cases, and the removal rate was 94.6%. Sixty-one cases were found to have thrombus on the filter after contrast examination or removal of vena cava filter, that is, the thrombus interception rate was 36.3%.ConclusionFor patients with lower limb or pelvic fracture combined with DVT, the rechargeable vena cava filter can effectively stop thrombosis and avoid pulmonary embolism.
