Objective To understand the characteristics of patients who have undergone the removal of the inferior vena cava (IVC) filter, so as to provide a reference for optimizing the clinical application strategy of IVC filters. Method The demographic and clinical characteristics of patients underwent IVC filter removal in the Division of Vascular Surgery, Department of General Surgery, West China Hospital, Sichuan University from December 2016 to December 2023 were retrospectively collected. Results A total of 102 patients were enrolled, including 48 (47.1%) males and 54 (52.9%) females. The age of the patients was (46.75±16.72) years old, and 75 (73.5%) patients were aged between 20 and 59 years old. The proportion of patients underwent retrieval after IVC filter placement due to combined central deep vein thrombosis was highest, accounting for 48.0% (49/102). Of the 102 patients, 72 (70.6%) patients underwent IVC filter removal within 90 d and 6 (5.9%) patients underwent IVC filter removal after more than one year. The median duration of filter placement for all patients was 35 d (ranging from 5 to 7 300 d). The filter was removed via interventional method in 92 (90.8%) patients and via open surgery in 10 (9.8%) patients. The endovascular retrieval failed in one of 92 patients and then the follow-up observation was selected. Compared with the interventional treatment, the patients who had the filter removal by open surgery had a longer placement time of the filter in the IVC (median: 136.5 d vs. 32.5 d, P=0.002). Conclusions From the analysis results of this cases data, patients with IVC filters don’t show obvious gender characteristics. The majority of them are young and middle-aged, and interventional method is mostly used for the removal of IVC filters. Patients who receive open surgery to remove the filter have a longer placement time in the IVC, suggesting the necessity of early removal of the IVC filter.
