Summary
Long-distance travel has a weak link to asymptomatic venous thromboembolism (VTE). Simple measures like hydration and movement are recommended, with specific prophylaxis for high-risk individuals.
Area of Science:
- Medical Science
- Public Health
Background:
- Literature suggests a weak association between long-distance travel and venous thromboembolism (VTE).
- Risk appears concentrated in asymptomatic calf vein thrombosis for passengers with risk factors traveling over 8 hours.
Purpose of the Study:
- To review the association between long-distance travel and VTE.
- To provide recommendations for VTE prevention during travel.
Main Methods:
- Literature review of existing studies on travel and VTE.
- Analysis of risk factors and preventive measures.
Main Results:
- The risk of symptomatic and fatal pulmonary embolism (PE) from travel is very low.
- Causal travel-related factors like stasis and dehydration are not definitively proven.
- No evidence supports routine thromboprophylaxis for all travelers.
Conclusions:
- Passengers should maintain hydration and exercise during travel.
- Graduated compression stockings or low-molecular-weight heparin may be considered for high-risk individuals.
- Aspirin is not recommended due to adverse gastrointestinal effects.
