Feasibility and safety of “filter-thrombus integrated retrieval technique” based on controlled deformation of spindle shaped IVC filters for complex IVC filter retrieval

The filter-thrombus integrated retrieval technique appears to be a safe and feasible strategy for managing thrombosed filters. Through a unique physical "caging" mechanism, this technique minimizes the risk of iatrogenic PE during retrieval without relying on additional thrombolysis or aspiration devices. It presents a viable option for patients with high thrombus burden or contraindications to anticoagulation.
