经常远程乘高速喷气式民航客机的人士,有的可能在机上或下机后发现自己下肢踝部有水肿现象,这在医学上称之为‘喷气式飞机飞行腿’,是一种与高空长时间飞行有关的良性暂时性病症。喷气式飞机飞行腿是高空长时间飞行的‘环境病’,特别在30岁以上的妇女及有静脉曲张的人中常见。一般在飞行3小时后即可发现踝部有水肿,从踝部轻度按压凹陷至下肢肿胀均可发生,但极小见于大腿。水肿的严重程度与飞行高度、飞行持续时间以及机舱温度有关。患者可能感到不适,但当时或其后小腿不觉疼痛或触痛,也未见有深部静脉血栓形成。 People who often fly high-speed jet airliners remotely may find that their lower extremity ankles have edema on or off the plane. This is called “jet flight leg” medically, Time-related benign temporary illness. Jet jets are legally “environmental” flying long flights, especially among women over the age of 30 and those with varicose veins. Usually 3 hours after the flight can be found ankle swelling, mild depression from the ankle to lower limb swelling can occur, but rarely found in the thigh. The severity of edema is related to flight altitude, flight duration, and cabin temperature. The patient may feel unwell, but at the time or thereafter the calf felt pain or tenderness and no deep venous thrombosis was seen.
