The study on sectional anatomy and imaging of accessory hepatic veins.
[child syndrome]
To
evaluate
the
distribution
and
clinical
value
of
accessory
hepatic
veins
(
AHVs
)
,
we
investigated
the
number
and
caliber
of
the
AHVs
and
the
angles
between
the
shafts
of
AHVs
and
inferior
caval
vein
.
We
analyzed
the
anatomical
dissections
,
serial
transverse
and
coronal
sections
(
0
.
1
-
0
.
2
mm
)
of
a
frozen
liver
,
and
the
ultrasonographical
and
enhanced
CT
images
of
healthy
patients
.
We
found
that
:

Most
of
the
angles
between
the
AHVs
and
inferior
caval
veins
on
the
thin
sections
(
78
%
)
and
liver
dissections
(
72
%
)
were
acute
(
P
<
0
.

)
,
while
the
AHVs
with
right
angles
had
significantly
larger
average
calibers
(
P
<
0
.
05
)
.
However
,
on
the
contrary
,
most
of
the
angles
between
the
AHVs
and
inferior
caval
veins
were
right
angles
as
observed
in
ultrasonography
(
89
%
)
and
spiral
CT
images
(
83
%
)
(
P
<
0
.
01
)
.
The
angle
parameters
appear
to
be
more
selective
when
displaying
the
AHVs
on
ultrasonography
and
spiral
CT
images
.
(

)
The
presentation
rates
of
the
AHVs
in
ultrasonic
and
spiral
CT
images
were
much
lower
than
those
of
the
anatomical
dissections
(
P
<
0
.
01
)
.
(

)
There
were
no
apparent
differences
in
displaying
right
inferior
hepatic
veins
between
ultrasonography
and
spiral
CT
(
P
>
0
.
05
)
.
However
,
the
presentation
rate
of
small
AHVs
was
much
lower
in
spiral
CT
images
(
P
<
0
.
05
)
.

The
ultrasonographical
and
spiral
CT
scans
provide
effective
reference
for
the
diagnosis
of
Budd-child
syndrome
,
hepatectomy
,
especially
liver
hanging
maneuver
.
