课文(一):坐飞机坐出的血栓

三十几岁的小王由于工作原因,常常乘飞机到世界各地出差。前不久,刚下飞机小王便感到胸闷、气短,身体非常难受。到医院检查,他的胸部CT显示:双侧肺动脉栓塞,以右侧为重。原来小王患上了“经济舱综合征”。

所谓“经济舱综合征”,又叫“下肢静脉血栓”,它是指乘坐飞机经济舱的乘客,由于长时间坐在相对狭小的座位上不动,导致双下肢静脉血液循环不畅通,发生凝固形成血栓,下飞机活动后血栓脱落,并随血液流经右心室到达肺动脉,阻塞肺动脉,即医学上所说的“肺栓塞”,其后果轻者引起呼吸困难、胸痛等,重者可引起猝死

不过,“经济舱综合征”不是坐飞机经济舱所特有的。事实上,不论是坐飞机还是火车、长途汽车,甚至是在办公室里,只要是长时间坐着不动,人体下肢静脉都容易形成血栓,进而有发生“肺栓塞”的可能。

引起血栓的另一个因素是血液黏稠。一般来讲,体重过重和高血脂高尿酸、糖尿病患者,以及正服用避孕药的妇女,患“经济舱综合症”的几率比较高,应当注意预防。

Text (1): Thrombus from a Flight

In his 30s, Xiao Wang often flies to all parts of the world on business because of his work. Not long ago, just off the plane, Wang felt chest tightness, shortness of breath and the body is very uncomfortable. On examination at the hospital, CT of his chest showed bilateral pulmonary embolism, with emphasis on the right side. It turned out that Wang suffered from “economy class syndrome”.

The so-called “economy class syndrome”, also known as “lower limb venous thrombosis”, points to the plane economy class passengers, because sitting for a long time in a relatively narrow seat motionless, can lead to lower limb venous stagnation and coagulation with the formation of thrombosis. The thrombosis can be dislodged, and with the blood flow through the right ventricle to the pulmonary artery, blocks the pulmonary artery, namely “pulmonary embolism”. This causes dyspnea, chest pain, and can cause sudden death.

However, the economy class syndrome is not specific to flying economy class. In fact, no matter by plane or by train or bus, or even in the office, as long as you sit still for a long time, the veins of the lower limbs of the human body easily form thrombus, and then there is the possibility of “pulmonary embolism”.

Another factor causing the thrombus is the thick blood. In general, overweight and hyperlipidemia, high uric acid, diabetes, and women taking contraceptives, have a higher risk of suffering from “economy class syndrome” and travelers should pay attention to prevention.
