Jonathan Cohen



Risk factors for thrombosis should be routinely sought in all travellers and preventive strategies discussed.

Article Extract

Pulmonary embolism (PE) following air flight was first described in 1954, and was termed economy class syndrome in 1977. This term is no longer used as we now know that venous thromboembolism (VTE) is not restricted to economy class passengers. Yet more than 50 years on from its first description we still lack definitive evidence based on adequately designed epidemiological studies for air flight being a cause per se of VTE.
