Anti-embolism stockings (also known as thrombo-embolic deterrent stockings) are designed to help prevent blood clots from forming in the legs. They work by creating a gentle pressure gradient that promotes blood flow in the deep veins of the legs, helping to prevent blood from pooling and forming clots. Here's how they work:
- Compression: Anti-embolism stockings are designed with a lower compression level than medical compression stockings, typically around 18 mmHg. The compression is applied evenly over the entire length of the stocking, with a slightly tighter fit around the ankle and gradually loosening towards the top of the leg.
- Graduated compression: Like medical compression stockings, anti-embolism stockings are designed with a graduated compression pattern. The compression is strongest at the ankle and gradually decreases as it goes up the leg, helping to promote blood flow back to the heart.
- Enhance blood flow: The gentle pressure created by the stockings helps to enhance blood flow in the deep veins of the legs, reducing the risk of blood pooling and clotting. This can be especially helpful for people who are at risk of developing blood clots due to prolonged periods of immobility, such as during surgery or long-distance travel.
- Reduce the risk of deep vein thrombosis: By promoting blood flow and reducing the risk of blood clots, anti-embolism stockings can help to prevent deep vein thrombosis (DVT), a potentially life-threatening condition where a blood clot forms in a deep vein, usually in the legs.
Overall, anti-embolism stockings are an effective and non-invasive way to prevent blood clots in the legs. However, they should be used under the guidance of a healthcare professional and are typically recommended for people who are at risk of developing blood clots due to immobility or certain medical conditions.
