Endoscopic third ventriculostomy in children younger than 2 years of age.
[hydrocephalus with stenosis of the aqueduct of sylvius]
Endoscopic
third
ventriculostomy
(
ETV
)
for
the
treatment
of
hydrocephalus
of
different
etiologies
is
still
controversial
in
children
younger
than
2
years
of
age
.
The
success
rate
of
ETV
in
this
group
of
patients
is
analyzed
in
this
study
.
The
series
consisted
of
21
patients
treated
with
ETV
.
The
mean
age
of
the
patients
was
6
.
7
months
,
ranging
from
9
days
to
15
months
(
16
patients
were
younger
than
1
year
)
.
The
study
included
hydrocephalus
due
to
idiopathic
aqueductal
stenosis
(
eight
)
and
other
congenital
anomalies
(
four
)
as
well
as
posthemorrhagic
(
three
)
and
tumor
-related
occlusive
hydrocephalus
(
three
)
.
Two
patients
presented
with
shunt
infection
and
one
with
a
shunt
failure
.
ETV
was
considered
to
be
successful
when
shunting
could
be
avoided
.
ETV
was
successful
in
nine
patients
,
with
a
mean
follow-up
period
of
26
.
2
months
.
The
procedure
was
successful
in
four
patients
with
idiopathic
aqueductal
stenosis
,
in
two
with
other
congenital
anomalies
,
in
one
posthemorrhagic
,
and
in
two
with
a
tumor
-related
hydrocephalus
.
In
12
patients
,
the
ETV
was
unsuccessful
after
a
mean
follow-up
of
3
.
3
months
.
These
patients
required
a
shunt
.
Ten
of
them
were
less
than
1
year
old
when
ETV
was
performed
.
In
one
tumor
-related
hydrocephalus
,
a
shunt
was
inserted
after
a
meningitis
after
tumor
removal
.
The
success
of
ETV
in
children
younger
than
2
years
of
age
suffering
from
non-
communicating
hydrocephalus
seems
to
be
dependent
on
both
age
and
etiology
.
Our
results
show
an
overall
success
rate
of
43
%
.
In
37
.
5
%
of
the
children
younger
than
1
year
of
age
,
ETV
was
successful
.
ETV
in
patients
with
hydrocephalus
due
to
idiopathic
aqueductal
stenosis
seems
to
be
more
beneficial
than
in
other
causes
of
hydrocephalus
.
