One in 100 gets DVT, says research
As many as five passengers on every Boeing 747 are likely to develop blood clots because of deep vein thrombosis, according to a report published today. The Financial Times highlights a study published in the medical journal the Lancet, which suggests the condition affects as many as one in 100 travellers, some 10 times more than had previously been thought. The research, carried out by the Medical Research Institute of New Zealand, was carried out on some 878 people making return flights from Auckland, New Zealand; none of them were especially at risk of developing the condition. Some nine people developed DVT; five in deep veins in their legs and four in their lungs. According to the FT, the researchers said the results were probably “conservative” because the sample of travellers was probably “more aware than average” about DVT and many had taken precautions; 31 per cent had taken aspirin and 17 per cent were wearing compression stockings. The newspaper states that two of the travellers had been in the business class cabin, this matched the DVT incidence of the whole sample and appears to make redundant the term “economy class syndrome” often applied to the condition. Prof Richard Beasley, who carried out the research, reportedly said: “Our findings suggest that venous thromboembolism is a potentially important health problem for many long-distance air travellers, including those without recognised risk factors.”
