Summary
Flying may increase the risk of blood clots, a prospective study found. Graduated elastic compression stockings significantly reduced this risk in passengers, suggesting a potential preventative measure for air travel.
Area of Science:
- Cardiovascular Health
- Aerospace Medicine
- Thromboembolic Disease Research
Background:
- Anecdotal evidence suggests a link between air travel and blood clot formation.
- Venous thromboembolism (VTE) is a significant public health concern, particularly in relation to immobility.
- Understanding risk factors associated with prolonged travel is crucial for preventative strategies.
Purpose of the Study:
- To investigate the incidence of asymptomatic venous thrombosis in air passengers.
- To evaluate the efficacy of graduated elastic compression stockings in preventing travel-related thrombosis.
- To identify areas for further research into symptomatic VTE and cabin environmental factors.
Main Methods:
- Prospective study design involving passengers before and after flights.
- Assessment of asymptomatic venous thrombosis using validated diagnostic methods.
- Interventional component evaluating the impact of graduated elastic compression stockings.
Main Results:
- A higher-than-expected incidence of asymptomatic venous thrombosis was observed in passengers.
- Graduated elastic compression stockings demonstrated a reduction in the incidence of asymptomatic venous thrombosis.
- The study provides quantitative data on the prevalence of subclinical thrombosis post-flight.
Conclusions:
- Air travel is associated with a significant risk of developing asymptomatic venous thrombosis.
- Graduated elastic compression stockings are effective in mitigating this risk.
- Further research is warranted to assess symptomatic VTE and the influence of cabin conditions.

01:24Disorders of Hemostasis
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

01:30Venous Thrombosis I: Introduction
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
01:20Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
01:29Venous Thrombosis III: Interprofessional Care
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
01:29Pulmonary Embolism I: Introduction
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...
01:19Pulmonary Embolism I: Introduction
A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...
