An observational study in Venous Thromboembolism, sponsored by Stanford University. Recruiting at 1 site in United States. Per ClinicalTrials.gov, last updated 2025-09-26.
Sponsored by Stanford University · Observational
A prospective data registry for all patients who undergo IVC (Inferior Vena Cava) filter placement or retrieval at Stanford. Potential enrollees will already be undergoing the procedure. If patients are willing, they will be prospectively enrolled prior to the procedure. As part of the study, chart and clinical data reviews will be used to track patient progress and response to the treatment.
Patient clinical data will be used in a clinical registry. Before a patient is to undergo their initial procedure for filter placement/retrieval, we will approach them for consent to participate in the study. If patients consent, we will follow clinical data from the procedure, and perform prospective follow-up over time to track clinical response and effects of the placement or removal procedure.
Various real-world protocols involving advanced filter removal (including laser-assisted filter removal) will be investigated by conducting registry-based clinical trials.
Participants will only be enrolled if they will be undergoing an IVC (Inferior Vena Cava) filter placement/retrieval procedure.
694 studies on the registry are indexed under Venous Thromboembolism; 152 are open to participants now.
This study's planned enrollment of 5,000 is above the median of 700 across 283 observational studies indexed under Venous Thromboembolism.
