I always recommend my patients to be active after a Brazilian butt lift. You should stay in the area where you had the procedure done for at least 7 days to make sure that everything is going well, your pain is well controlled, and that you are in good condition to be on a flight for a long period of time. Clots do not typically occur on healthy patients after surgery unless the patient was not active after the procedure. Immobility after surgery increases the risk of clots after surgery due to the pooling of the blood in the larger vessels of your leg, thus setting the stage for a cascade of events that result in clots. Most patients after a Brazilian butt lift do not complain of significant pain. If your pain threshold is low, then, this needs to be addressed before your flight so you can move around without significant problems. Anticoagulation in a healthy patient is currently controversial. There is consensus by most surgeons that patients with high risk for clots should have anticoagulation prophylaxis. On the other hand, cosmetic patients usually do not have significant risk factors to justify anticoagulation. Nevertheless, I sometimes use certain medications, such as Lovenox, on a patient-to-patient basis. For example, if I notice that the patient is not very active, pain threshold is low preventing the patient from moving, or if taking a long flight after surgery among others, I will suggest anticoagulation. Remember it can be a catch of 22 because anticoagulation can prevent clots but can also increase the chances of bleeding. In addition, anticoagulation needs to be done for two weeks after surgery since it is well known that you can develop a clot even in a period ranging from 10-14 days after surgery.
