Determination of the amount of parenchymal damage in nonalcoholic fatty liver disease (NAFLD) is crucial to choose the best treatment and management.


Here, the associations between laboratory data and severity of steatosis and fibrosis plus hepatic vessel Doppler indices in NAFLD patients were investigated.

Patients and Methods:

Fifty patients (20 males and 30 females) with NAFLD criteria were enrolled. Fatty liver was graded by sonography (SGFL) and FibroScan (FGFL). In addition, liver fibrosis was graded through FGLF. Damages to the portal, hepatic, and splenic veins were evaluated by color Doppler/dopplex. Serum liver enzymes and C-reactive protein (CRP) were also measured.


Significant association existed between SGFL and FGFL (P = 0.006). Portal vein pulsatility index (PI) and phasicity plus the triphasic and monophasic pattern of hepatic veins significantly associated with fatty liver grade evaluated by sonography. Splenic vein Peak systolic velocity and PI showed significant association with FGFL. Eventually, elevated liver enzymes and CRP significantly correlated with FGLF.


We found that the severity of fatty liver is correlated with hepatic and portal veins damages; however, the degree of parenchymal fibrosis was independent to these indices and can be directly evaluated by FGFL. In addition, elevated liver enzymes and CRP correlated with the degree of fibrosis.
