Individuals who underwent a total hip replacement had at least four
times the risk of suffering a stroke in the
weeks immediately following, a Dutch study reported.
more cautious monitoring after such a procedure is warranted.
Hip replacement patients showed nearly five times the rate of
ischemic stroke than a control group. The rate of hemorrhagic stroke was a little more than four times
as much. The rates were highest in the two weeks following surgery but
declined quickly thereafter, evening out after six to 12 weeks, said
Frank de Vries, PharmD, PhD, of the Utrecht Institute of Pharmaceutical
Sciences in the Holland, one of the researchers. His team's work is
detailed online in Stroke: Journal of the American Heart Association.
“Risk assessment of stroke in individual patients undergoing total
hip replacement (i.e. evaluate other risk factors for stroke) should be
considered during the first 6 to 12 weeks,” the researchers wrote.
They examined records of 200,000 individuals,
including more than 66,000 who had total hip replacement from 1998 to
2007, to reach their findings.
