Each
year
锛?/p>
half
a
million
people
die
from
brain
aneurysms(
鍔ㄨ剦鐦?/p>
)
鈥?/p>
when
a
blood
vessel
bursts
in
the
brain.An
aneurysm
is
a
bulge
in
a
blood
vessel
that
can
burst.If
that happens in the brain
锛?/p>
it can be deadly.For survivors
锛?/p>
physical disabilities
are
often
severe.They
may
include
memory
problems
锛?/p>
loss
of
balance
锛?/p>
trouble
speaking
and
even
blindness.But
new
technologies
are
increasing
survival
rates
and
reducing
disabilities.
Beaumont Bacon is a survivor who makes light of her experience because she is
a
comedian.She
uses
humor
to
make
others
laugh.Now
she's
working
on
a
new
show.Michael
Alexander
is
her
doctor.He
operated
on
Beaumont
Bacon
after
her
attack.鈥淪he had bleeding in the frontal area of her brain锛?/p>
so right above the
eyes.The part that was in the brain was about maybe the size of an egg.So
锛?/p>
that's
a fairly large bleed.鈥?nbsp;
Ms.Bacon
had
a
better
chance
at
survival
than
most
people
because
of
Dr.Alexander.He directs the Neurovascular Center in Los Angeles.The center offers
new technologies that include placing a catheter(
瀵肩
) into an aneurysm
锛?/p>
then
threading wires to promote blood clots(
琛�鏍?/p>
)
锛?/p>
This technique reduces the chances
of another burst blood vessel.鈥淵ou don't have to open up the skull or open up the
brain to do surgery.It's all done from inside the blood vessels.So it reduces the
amount of blood loss
锛宎nd the recovery is much faster.鈥?/p>
For
Beaumont
Bacon's
recovery
锛?/p>
the
hospital
worked
to
prevent
problems
commonly
found in patients with a burst aneurysm.The problems include brain swelling that
can
shut
down
blood
vessels.She
spent
a
month
in
a
coma(
鏄忚糠
)
鈥?/p>
unable
to
communicate
with
doctors
锛?/p>
friends
and
loved
ones.But
with
a
year
of
treatment
锛?/p>
she
recovered.Now
锛?/p>
she is making people laugh.
