A retrospective study on the clinical outcomes of endovascular intervention treatment for inferior vena cava filter thrombosis - Research Open Access

Sep 30, 2026

A retrospective study evaluates the feasibility and safety of tailored endovascular intervention strategies for inferior vena cava filter thrombosis (IVCFT), aiming to optimize thrombus clearance, filter retrieval success, and restoration of inferior vena cava (IVC) patency. 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 complications.

Methods A retrospective analysis was performed on 31 patients who were treated in our center from January 2020 to December 2022 with diagnosis of inferior vena cava filter thrombosis (IVCFT) . 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. Results 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. Conclusions Endovascular intervention therapies, including MAT, CDT, ART, and stent implantation, are safe and feasible in IVCF retrieval and restoration of IVC venous patency.

FAQs

What clinical outcomes were assessed in the study of IVCF thrombosis?

The study assessed thrombus clearance rate and grade, IVCF retrieval rate and post-retrieval thrombus status, restoration of IVC patency, and procedure-related complications.

Which endovascular intervention methods were used?

Manual aspiration thrombectomy, catheter-directed thrombolysis, AngioJet rheolytic thrombectomy, and balloon dilatation with stent implantation were used either individually or in combinations based on thrombus characteristics.

What were the key findings on safety and feasibility?

The reported success rate of endovascular techniques was 100%, most primary filters were successfully removed, IVC patency restoration reached 100%, and no serious complications such as massive hemorrhage or pulmonary embolism occurred during procedures.
