Hi Steph5678, The baseline risk for blood clots in the overall tummy tuck population is 0.2%, or 1 patient in 500, based on great data from ~129,000 aesthetic surgery patients in a database called CosmetAssure. However, based on your description, you would be at higher risk than most. You have a known genetic predisposition for blood clots (Factor V Leiden), and have had a personal history of blood clots. These two risk factors, coupled with the potential of having a surgery under a general anesthetic, elevate your risk for clots. It will be important for you and your surgeon to discuss your risk for blood clots after surgery. Your surgeon should identify any other risk factors that are modifiable (such as oral contraceptive use, elevated body mass index, varicose veins, and others), and remove those prior to surgery. Other risk factors, like your personal history of clots and genetic hypercoagulability, can unfortunately not be changed. Prior to surgery, you should discuss your risk level with your surgeon, and the two of you should make an informed decision about whether to move forward or not. If you have surgery, sequential compression devices (leg squeezers) can decrease your risk for clots by physically propelling blood out of your legs during surgery. There is a straight line relationship between time spent under anesthesia and risk for clots, and so you and your surgeon should discuss the appropriateness of concurrent or additional procedures, balancing your goals with your risk level. You and your surgeon should also discuss the role of blood thinners/anticoagulants, if you elect to move forward with surgery. The attached video is a talk I gave at the American Society of Plastic Surgeons meeting a few weeks ago on this very topic--it should help you identify potential talking points for you and your surgeon.
