Effects of fatty filtration at the pediatric liver hemodynamic changes evaluated by Doppler ultrasonography

Abstract

Background: Hemodynamic changes in liver vascular structures of patients in the pediatric age group are evaluated by doppler ultrasonography. Material: Fifty- nine hepatosteatosis patients, classified as mild, moderate or severe, and 23 healthy volunteers were included in this 82-person study. The height, weight, liver size tests of the subjects were measured. Those values were compared in the patient and control groups. In the patient and control groups, color duplex Doppler ultrasonography was used to examine portal vein peak velocity, portal vein flow volume, hepatic artery resistive index (RI), hepatic artery pulsatility index (PI) and hepatic artery flow volume. Results: Similar to the degree of hepatosteatosis, increases in body mass index, liver size were statistically significant (p<0.05). The difference between portal vein peak velocity hepatosteatosis and control groups was found statistically significant. As the hepatosteatosis grade increased, there was no statistically significant decrease in hepatic arterial flow volume, portal vein flow volume, and total flow volume. Hepatic artery RI and PI values ​​were statistically significantly lower in the control group than the other groups (p <0.05). There was a significant mild decrease in the mild stool group compared to the middle steat group. Although the hepatic artery RI and PI values ​​did not differ statistically in the comparison of the hepatosteatosis group, there was a minimal increase in the RI and PI values ​​as the steatosis grade increased. Discussion: According to these results, as the level of steatosis increases, the changes in the portal venous structures become more prominent and the resistance increases in vascular structures.
