There is an increasing suspicion among the travelling public and the international media of an association between the occurrence of deep venous thrombosis (DVT) and air travel. It was noted by the UK House of Lords Select Committee on Science and Technology that up to 20% of the total population may have some degree of increased clotting tendency. It follows that some air travellers are at risk of developing DVT when, or soon after, travelling. There have been no epidemiological studies published which show a statistically significant increase in cases of DVT when travelling in the absence of pre-existing risk factors. The literature was reviewed. Current evidence indicates that any association between symptomatic DVT and travel by air is weak, and the incidence is less than the impression given by recent media publicity.
出行公众和国际媒体越来越怀疑深静脉血栓形成（DVT）的发生与航空旅行之间存在关联。英国上议院科学技术特别委员会指出，高达20%的总人口可能有某种程度的凝血倾向增加。因此，一些航空旅行者在旅行期间或旅行后不久有发生DVT的风险。尚未发表任何流行病学研究表明，在没有预先存在的风险因素的情况下旅行时，DVT病例有统计学上的显著增加。对相关文献进行了综述。目前的证据表明，有症状的DVT与航空旅行之间的任何关联都很弱，其发病率低于近期媒体宣传所给人的印象。
