There is nothing mysterious about air travel and clots: sitting at home or in a car for the same period of time would also increase the risk of a clot. If your daughter follows your exercise schedule and gets up and walks through the aisle every hour or so, she should be fine. One way to decrease the risk of future clots would be to continue to take one baby aspirin a day - this decreases the function of blood platelets, which are important in clotting. If your daughter has additional problems with clots in the future she should have a repeat lupus anticoagulant test and a test for anti-phospholipid antibodies to see if her antibody levels have increased. If so, treatment with stronger anticoagulants, such as warfarin, should be considered. Your daughter should also be aware that tobacco smoking and birth control pills increase the risk of developing clots.
