Abstract |
Budd-Chiari syndrome (BCS) is a rare clinical entity
characterized by post-sinusoidal portal hypertension
caused by the obstruction to the hepatic vein outflow.
The diagnosis is suggested by hepatic scintigraphy and
is usually confirmed by hepatic venography, inferior
vena cavography and biopsy. The scintigraphic finding
of BCS caused by the obstruction of main hepatic vein
has been reported to consist typically of hypertrophy
of the caudate lobe with increased radionuclide
accumulation. Such a typical finding has been accounted
for by the fact that the venous outflow from the
caudate lobe is preserved when the main hepatic vein is
obstructed. But usually, the hepatic venous outflow
from the caudate lobe is also obstructed in BCS due to
inferior vena caval obstruction. So hepatic
scintigraphic findings of BCS due to inferior vena
caval obstruction show different findings as compared
with the BCS due to hepatic vein obstruction. We
evaluate the hepatic scintigrams of the 13 cases of BCS
due to inferior vena caval obstruction and review the
literatures. The results are as follows: 1) We cannot
observe the caudate lobe hypertrophy with increased
uptake, which is known as a classic finding in BCS due
to hepatic vein obstruction. 2) The most prominent
hepatic scintigraphic findings of BCS are nonhomogenous
uptake in the liver with extrahepatic uptake in the all
cases. 3) We can see cold areas at the superior aspect
of right hepatic lobe in 7 cases (54%). This is a
useful finding suggesting BCS due to inferior vena
caval obstruction. |
