Total hip replacement
surgery is widely becoming popular in Europe and United States. Every year
about 1 million total hip replacement surgeries are done.
According to a recent
research published in the American Heart Association journal Stroke
, in the
first two weeks after the total hip replacement surgery, the risk of ischemic
stroke increases 4 to 7 times and hemorrhagic stroke increases 4.4 times.
Frank de Vries, Ph.D.,
Pharm.D., the lead author of the study and assistant professor of
pharmacoepidemiology at Utrecht University in the Netherlands said, "This is
the first study to evaluate the risk of stroke in patients undergoing total hip
replacement compared to people in the general population who did not undergo
the surgery, but were matched for age, sex and geographical region."
stated, "It makes sense to evaluate the risk of stroke two weeks after surgery.
There is an increasing tendency to decrease the length of hospital stay because
of improved therapy and because of strategies to reduce costs and mobilize
patients as soon as possible."
enrolled 66,583 patients in Danish registries who underwent total hip
replacement surgery and evaluated them against 199,995 people who did not have
surgery. The volunteers were aged between 70 and 72 years, mostly Caucasians
and 63.1 percent of them were females.
discovered that the risk of stroke was four times more in patients who had
total hip replacement surgery as compared to those who did not have the

Prof Cyrus Cooper of
the University of Southampton said that the risk of stroke was two times more
with total hip replacement surgery as compared to any other general surgery.
The scientists said
that aspirin intake could lower the risk of blood clot.
Prof Cooper said,
"This research has demonstrated that there is a high risk of stroke to patients
soon after having a total hip replacement and suggests that the use of soluble
aspirin might be beneficial in reducing this risk. He added, "Normally we would
have reservations about people taking aspirin every day but our results suggest
aspirin is a benefit and worthwhile to give to the patient before the surgery."
surgery is a major traumatic operation and like any other surgery there is
always a threat of further health ailments.
The researchers said that if you are intending
to go for a total hip replacement surgery, it is advisable to speak to your
general physician and discuss the associated potential risks.
