[Use of compression stockings during flights].

Flights longer than four hours pose a risk of venous thromboembolism in the general population, and the risk increases when additional risk factors are present. Compression stockings have proven beneficial on deep as well as superficial vein thrombosis and oedema during long-haul flights, without causing side effects or discomfort. However, no data exist for flights shorter than four hours. Passengers can use compression stockings as general prophylaxis, and this should be recommended based on an assessment of endogenous risk factors and the duration of the travel.
