How many young people die from dvt in uk?

Estimate 25K/yr: Your House of Commons in 2005 estimated that 25,000 men & women die every year from hospital acquired venous thromboembolism. So while we don't die directly from deep vein thrombosis, death can occur when blood clot breaks free & blocks blood flow in lungs eg pulmonary embolism. Unfortunately, I could not determine breakdown by age http://www.nice.org.uk/guidance/CG92/chapter/introduction.
