Brief Summary:
A 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.

Condition or disease Intervention/treatment
Venous Thromboembolism Procedure: IVC Filter Placement or Retrieval

Detailed Description:

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 do chart reviews over time to track progress of the filter and response to the procedure to place/remove the filter.

Participants will only be enrolled if they will be undergoing an IVC (Inferior Vena Cava) filter placement/retrieval procedure. The procedure itself is not being performed as part of the study.
