In some cases, a vena cava filter may be inserted into the vena cava (the large vein which returns blood from the body to the heart) of patients who cannot take medication or if blood thinners are not working. The filter is a kind of "clot catcher."
Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.
Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.
