Filters and Compression Stockings
If anticoagulants do not work or you cannot take blood thinners, your doctor may insert a filter into the inferior vena cava located in the abdomen. This device can help trap or capture a blood clot to prevent it from reaching the lungs or heart. Filters should be only a short-term solution until you can take medications. Leaving them in the long term may actually cause venous thrombosis. [2]
A simple way to reduce the risk of venous thrombosis is to wear compression stockings. These are special socks that can prevent blood from clotting and reduce the risk of swelling. You need to wear them on the legs right above or below the knee. It is better to wear them every day for a few months to get the best results. Compression stockings can be easily purchased from any drug store or pharmacy. They are typically elastic to improve blood circulation and reduce swelling. [3]
