London: The risk of having a potentiallyfatal blood clot after surgery is higher and lasts for longerthan had previously been thought, research led by theUniversity of Oxford has said.
The risk of blood clots is known to increase aftersurgery, particularly after major orthopaedic surgery such aship replacements. The risk is thought to be highest during thefirst few weeks after an operation but little is known aboutthe exact pattern and scale of this increased risk. "We have known for a long time that blood clots aremore common after some kinds of surgery, but we haven`t had aclear picture of the size of these risks before, or of howlong they last," says Dr Jane Green, one of the study authorsat the Cancer Epidemiology Unit.PTI
