What It Is and Why It Is Important
- Many factors influence a surgery patient's risk of developing a blood clot, including the type of surgery. When patients stay still for a long time after some types of surgery, they are more likely to develop a blood clot in the veins of the legs, thighs, or pelvis. A blood clot slows down the flow of blood, causing swelling, redness, and pain. A blood clot can also break off and travel to other parts of the body. If the blood clot gets into the lung, it is a serious problem that can sometimes cause death.
- Treatments to help prevent blood clots from forming after surgery include blood-thinning medications, elastic support stockings, or mechanical air stockings that help with blood flow in the legs. These treatments need to be started at the right time, which is typically during the period that begins 24 hours before surgery and ends 24 hours after surgery.
