Travel-related thrombosis occurs in 1/6,000 individuals who fly long-haul flights. The risk is increased significantly in passengers with thrombophilia and during hormonal therapy. Pregnancy is a hypercoagulable state with 5-10-fold increase in VTE risk. Mechanisms for hypercoagulation on air are related to cabin atmospheric conditions, with immobility and flight duration playing a major role. Prophylactic measures include frequent exercise in all passengers, elastic stockings and LMWH in travelers at high risk.
长途飞行的人群中，与旅行相关的血栓形成发生率为千分之一。血栓形成倾向者以及接受激素治疗的乘客发生这种风险的几率会显著增加。怀孕是一种高凝状态，静脉血栓栓塞（VTE）风险会增加5至10倍。飞行过程中导致血液高凝的机制与机舱内大气条件有关，其中不动和飞行持续时间起主要作用。预防措施包括所有乘客都要经常运动，高风险旅行者要穿弹力袜并使用低分子肝素。
