Epidemiological studies show that the risk of venous thromboembolism doubles after long haul air travel of more than four hours' duration, a World Health Organization report says.
The final report of phase I of the WHO research into global hazards of travel (WRIGHT) project concludes that the absolute risk of venous thromboembolism among healthy individuals for a flight of more than four hours was 1 in 6000. Pathophysiological studies, it says, support these findings.
The studies were carried out by an international collaboration of researchers from …
