Abstract:
UNLABELLED:Early monitoring of non-alcoholic fatty liver disease (NAFLD) progression in obese patients is important to avoid the development of complications associated with fatty infiltration. THE AIM:of this study was to investigate the relationship between the degrees of fatty infiltration and reduced vascular compliance in NAFLD patients in the three main hepatic vessels. MATERIAL AND METHODS:Two hundred and fourty subjects were enrolled in the study. They were divided into 4 groups: 60 controls, 60 grade 1 NAFLD patients, 60 grade 2 NAFLD patients and 60 grade 3 NAFLD patients. After US confirmation of the presence and grade of NAFLD, the peak and mean portal vein velocity (PPVV and MPVV, respectively), the hepatic artery resistance index (HARI), and the phasicity of the hepatic vein were measured. RESULTS:The PPVV was 19.6 +/- 2.4 cm/sec in patients with grade 1 fatty liver, 17.6 +/- 1.2 cm/sec in grade 2 and 15.4 +/- 1.1 cm/sec in grade 3. The MPVV was 16.6 +/- 2.4 cm/sec in patients with grade 1 fatty liver, 16.6 +/- 2.9 cm/sec in grade 2 and 12.7 +/- 0.7 cm/sec in grade 3. The HARI was 0.75 in patients with grade 1 fatty liver, 0.68 in grade 2 and 0.64 in grade 3. There was an inverse relationship between PPVV, MPVV and HARI and different grades of fatty liver in patients (p = 0.001 for PPVV (Figure 7) and HARI, p = 0.006 for MPVV. CONCLUSION:The values of the investigated liver blood flow parameters were inversely correlated with the fatty infiltration grading. Fatty infiltration can severely influence hepatic blood flow, pointing attention to the importance of early diagnosis and the need for hepatic vessel flow abnormalities characterization in the NAFLD population.
