Thank you for your question. In my practice with take several precautions to prevent blood clot formation. This includes a blood clotting risk assessment pre-operatively which is a scoring system unique to each patients medical history. I also have my patients wear thigh high compression stockings starting the morning of surgery and continually 2 days post surgery. In addition, compression foot devices are placed on patients during surgery which facilitates circulation in the legs and throughout the body. Post-operatively I recommend to be up and walking throughout the day. All these combined will lessen the risk of blood clot formation. As always it is important to follow the specific instructions of your plastic surgeon as they know what is best for your situation.
Unfortunately there is no way to eliminate the risk of developing blood clots, but there are many things that can be done to minimize the risk. Your health status and history need to first be evaluated for risk. Protocols are in place in the operating room to lower your risk such as the use of compression hose and sequential compression devices. Early ambulation is also important.
