Fig. 3 —Graph shows evolution of varices and spleen volume over time
after liver transplantation (LT). First CT scan was obtained within 2 weeks
after transplantation, second CT at approximately 2 months, third CT at 6
months, and fourth CT at 1 year after transplantation. Numbers on main
y-axis indicate mean value of variceal grade and numbers on second
y-axis indicate spleen volume on each CT. Solid lines indicate that
difference of mean values of variceal grade or spleen volume between each CT
and just-prior CT are statistically significant, whereas dotted lines indicate
difference is not significant. All varices except splenic and retroperitoneal
varices significantly decreased in diameter on CT performed within 2 weeks
after transplantation (p < 0.05). All varices except esophageal
varices became stable approximately 2 months after transplantation. On the
contrary, esophageal varices continuously and significantly decreased in size
even more than 1 year after liver transplantation. Spleen volume decreased
significantly within 2 weeks after transplantation and became stable after
that time.
