| description | Purpose
The aim of our study was to quantitate by Doppler sonography the blood flow in the right and left portal vein branches before and after a standard meal. We also assessed the functional response of the right and left lobes of the liver.
Methods
Portal blood flow was measured by Doppler sonography in the left and right portal vein branches and main portal trunk in 20 healthy volunteers in both fasting and postprandial states. The ratio between portal blood flow and liver volume (determined by MRI) was the portal flow index (PFI).
Results
Before the meal, a statistically significant difference in portal blood flow volume was observed between the right and left portal branches (p < 0.01). The right PFI (0.83 ml/minute/cm3) and left PFI (1.1 ml/minute/cm3) were also significantly different (p < 0.01). The increase in portal venous blood flow after a meal was found to be greater in the left portal branch (128%) than in the right portal branch (78%). The postprandial PFI also differed significantly (right, 1.54 ml/minute/cm3; left, 2.5 ml/minute/cm3).
Conclusions
These findings suggest that the left lobe of the liver has a better postprandial compliance than the right lobe has. © 1999 John Wiley & Sons, Inc. J Clin Ultrasound 27:75–80, 1999. |
