The family of a young woman who died after medics failed to spot a silent condition that kills thousands of Scots every year have spoken out two decades after her death.
Gordon and Jane McPherson, from Renfrewshire, and their son Stephen were left heartbroken when 23-year-old Katie died in January 2003 from deep vein thrombosis (DVT).
Katie was studying at Queen Margaret University in Edinburgh to be an occupational therapist when medics at two separate hospitals failed to spot a blood clot in her leg, instead giving her painkillers and sending her home.
