Thirty-one patients treated from January 2020 to December 2022 underwent manual aspiration thrombectomy, catheter-directed thrombolysis, AngioJet rheolytic thrombectomy, and/or balloon dilatation with stent implantation in various combinations. Outcomes include thrombus clearance grade, filter removal status, IVC patency, post-retrieval thrombus status, and procedure-related

Manual aspiration thrombectomy (MAT), catheter-directed thrombolysis (CDT), AngioJet rheolytic thrombectomy (ART), and balloon dilatation and stent implantation, either individually or in combination of 2 or 3 methods, were applied. Data of the thrombus clearance rate, inferior vena cava filter (IVCF) retrieval rate, thrombus status in the IVCF after retrieval of the filters, patency of inferior vena cava (IVC), and complications were collected and analyzed.  \nResults MAT was applied in 6 cases, CDT was applied in 10 cases, CDT plus MAT was used in 7 cases, ART plus CDT was used in 5 cases, combination of ART, CDT and MAT was used in 2 cases, and balloon dilatation and stent implantation following CDT was used in 1 case. The success rate of surgical technique in 31 patients was 100% . Except one primary filter, which was placed in other hospital 5 years ago, the rest 30 primary filters plus a secondary protective filter placed in one of the patients were successfully removed. Grade II or III was achieved in thrombus clearance by the endovascular mechanical therapies in this study. The restoration rate of IVC patency was 100% . No serious complications such as massive hemorrhage or pulmonary embolism occurred during the procedure of the endovascular intervention therapies.  \nConclusions Endovascular intervention therapies, including MAT, CDT, ART, and stent implantation, are safe and feasible in IVCF retrieval and restoration of IVC venous patency.  \nClinical trial number Not applicable.  \nKeywords Inferior vena cava filter, Thrombosis, Catheter-directed thrombolysis, AngioJet rheolytic thrombectomy  \n†Shiqiang Liao and Shuming Shi contributed equally to the article.  \n*Correspondence: Jianjie Rong [vascularRjj@163.com](vascularRjj@163.com)  \n1Department of Vascular Surgery, Suzhou TCM Hospital Affiliated to Nanjing University of Chinese Medicine, No. 18 Yangsu Road, Canglang NewTown, Gusu District, Suzhou City, Jiangsu 215009, China  \n© The Author(s) 2025.
