    • Is it safe to leave the filter in and does it has to stay there for my lifetime?
    • Can the filter be placed for blood clots in the arms rather than the legs?
    • With so many filter types which one is the best for me?


Blood clots from the large veins of the legs and pelvis can produce life threatening Pulmonary Embolism (PE) if left untreated such as when standard therapy cannot be used. PE management might include placement of an inferior vena cava filter effective in preventing PE. However filter does not reduce the risk to zero nor does it treat the underlying venous clotting problem. Therefore continued anticoagulant therapy (blood thinners) should be used when possible.
