1% of travellers may develop DVT

Researchers in New Zealand have discovered that up to 1% of long-haul travellers could develop blood clots as a result of their flight. Nine passengers out of a total of 900 developed deep vein thrombosis after a long flight. However, it was said that two-thirds of these had pre-existing medical problems that could have made DVT more probable. And four of the nine had worn compression stockings to improve blood flow in their lower limbs.
