Anecdotal reports have suggested a link between flying and the development of blood clots. A recent prospective study looking at passengers before and after flying has demonstrated a much higher incidence of asymptomatic venous thrombosis than we expected. In the same paper, graduated elastic compression stockings reduced this incidence of asymptomatic venous thrombosis. Further studies are required to see how many passengers develop symptomatic deep vein thrombosis and to assess the overall incidence of venous thromboembolic disease. A major epidemiological study, an interventional study to assess the efficacy of mechanical methods of venous thrombosis prophylaxis and the effect of graduated compression stockings, and studies to look at the effect of the cabin environment on thromboembolism are planned.
轶事报道表明飞行与血栓形成之间存在联系。最近一项针对乘客飞行前后情况的前瞻性研究显示，无症状静脉血栓形成的发生率比我们预期的要高得多。在同一篇论文中，分级弹力袜降低了无症状静脉血栓形成的发生率。还需要进一步研究来确定有多少乘客会发生有症状的深静脉血栓形成，并评估静脉血栓栓塞性疾病的总体发生率。计划开展一项大型流行病学研究、一项评估静脉血栓形成预防机械方法疗效及分级弹力袜效果的干预性研究，以及一项观察机舱环境对血栓栓塞影响的研究。
