AIMS: Veno-occlusive disease of the liver is a severe complication of
allogeneic bone marrow or peripheral stem cell transplantation with a high
mortality. In its severe form, the portal vein is used as an outflow tract
for the arterial hepatic perfusion. A portosystemic side-to-side shunt,
e.g. a transjugular intrahepatic portosystemic shunt, may facilitate portal
outflow thus increasing hepatic (i.e. arterial) perfusion. METHODS: The
effect of a transjugular shunt on liver function and blood flow was studied
in three patients receiving shunt treatment 0-2 days after the diagnosis
of severe veno-occlusive disease occurring 28, 20, and 17 days after allogeneic
transplantation for acute myeloid leukemia, Hodgkin's disease and chronic
myeloid leukemia, respectively. RESULTS: The transjugular shunt reduced
the portosystemic pressure gradient from 23 to 8, 18 to 5, and 33 to 13
mmHg in patients 1, 2, and 3, respectively, increased the stagnant portal
vein flow to normal, and decreased the arterial resistive index, indicating
an increase in the arterial perfusion of the liver. This was accompanied
by rapid relief from abdominal pain and removal of ascites. The AST concentration
dropped from 1230, 417, and 2930 U/l before to 93, 20, and 41 U/l and the
PT-time ratio improved 3-7 days after shunt treatment while the bilirubin
concentration continued to rise until the patients died 26, 42, and 33
days after transplantation from multiorgan failure (two patients) or intracerebral
hemorrhage. CONCLUSIONS: The transjugular shunt may have improved abdominal
and hepatic perfusion and prevented further necrosis of hepatocytes. It
did not, however, affect jaundice or survival, which was limited by extrahepatic
complications.
