NEURONAVIGATION
FOR
NEUROSURGICAL
OPERATIONS
Mr Chang had
headache,
dizziness
and
fits for
over
a
month
-
due
to a
cavernous
angioma, a benign blood ves-
sel tumor of
the
brain. Opera-
tion
was guided by
the
first
neuronavigation system
in
China installed
in
Huashan
Hospital, Shanghai
in
1997. lt
was
like a
compass throughout
the neurosurgical
operation
that
went
on
smoothly
and finished
promptly. Complication
rates
of
such an
operation
are
thus
much reduced compared with
those without such
systems.
With shorter operative
times,
operative costs also go
down.
Before operation, detail scans
of
his brain had already
been
input
to
computer;
during
operation, instruments
had
tags
for
real-time
spatial
positioning
registry
through two
infra-red
cameras. Such technologies
have
already been
in use
dur-
ing
the last
10 plus
years, first
in USA, Germany and Holland.
The
purpose
is
not
to
replace
conventional neurosurgical op-
erations
but, rather, to
enhance
the
quality
of
such operations
to
make
it
safer, more
reliable,
precise and scientific.
lt
may
even enlarge the scope of neu-
rosu
rgical operations.
