Introduction: Long-distance traveling in a sitting position may be associated with an increased incidence for venous thromboembolism. As major contributing factors immobility and compression of leg veins are discussed. At present no studies have been performed measuring the time course of lower limb blood flow, leg volume and leg tissue thickness during a long-haul flight.

- Long-distance travel by aircraft, bus, or car may increase the risk of thromboembolic events due to factors like prolonged sitting, rather than just hypoxia.
- A study measured coagulation markers and leg volume changes in healthy volunteers during a 10-hour bus journey, revealing moderate activation of coagulation.
- Results showed increased leg volume primarily in the calves post-travel, suggesting that long-distance travel can activate the coagulation system, questioning the role of hypoxia in thromboembolic risks.
Background: More than 1.5 billion passengers travel by aircraft every year. Leg edema, as a sign of venous stasis, is a well-known problem among passengers during and after long-haul flights.

Materials And Methods: To explore whether any changes occur in the coagulation system during a real long-haul flight molecular markers for coagulation and fibrinolysis were measured in 20 volunteers (10 subjects with a low and 10 with a moderate risk for venous thromboembolism (VTE)) during and after a return flight from Vienna to Washington.
