Economy class syndrome: still a recurrent complication of long journeys.Feltracco P, Barbieri S, Bertamini F, Michieletto E, Ori C Department of Pharmacology and Anesthesiology, University of Padua Hospital, Italy. paolofeltracco@inwind.it Economy class syndrome is a rare but still unavoidable complication of long haul flights, particularly in patients who carry various intrinsic risk factors. The tendency to affect even asymptomatic young people and the greater risk to fragment and propagate to the pulmonary circulation are the main characteristics of deep vein thrombosis of long-flight travelers. We report the clinical history of eight patients admitted to intensive care unit for confirmed or highly suspected economy class syndrome. Seven of them developed the syndrome within 72 h from a long return flight, one suffered from pulmonary embolism after a 12-h car trip. Two out of eight patients died, one because of extremely severe hemodynamic impairment, the other as a consequence of multiple organ failure caused by a concomitant myocardial infarction. Deep vein thrombosis and pulmonary embolism represent one of the main medical problems of air travel and cause almost 20% of deaths in people with no medical history. Although economy class syndrome occurs mostly in elderly, even the healthy young population can be affected and, in fact, three out of eight patients of our series were under 50 years of age. All our patients but one carried a well recognized risk factor for deep vein thrombosis. Clinical symptoms of deep vein thrombosis can sometimes be aspecific and confusing, so that a certain proportion of post-travel deep vein thrombosis, evolving favorably and not giving rise to pulmonary embolism, might effectively remain undiagnosed. Economy class syndrome is still quite difficult to deal with and controversial in terms of preventive strategies. Published 14 May 2007 in Eur J Emerg Med, 14(2): 100-3.
