Abstract
Objective: To assess hemodynamic changes in the liver in patients diagnosed with non-alcoholic liver steatosis by ultrasound. Methods: Clinical and prospective study with a quantitative approach. The sample consisted of patients of both sexes, aged 18 to 70 years. Through ultrasonography, they were diagnosed as having or not having non-alcoholic liver steatosis and submitted to a hemodynamic evaluation by Doppler flowmetry. The data were analyzed using the IBM SPSS 22.0 for Windows software and the significance level was p <0.05. Results: 145 patients were evaluated by abdominal ultrasound. Of these, 33 were diagnosed with non-alcoholic hepatic steatosis grade 1, 35 with grade 2, and 07 with grade 3. There was a change in the wave pattern of the hepatic vein, from three-phase to biphasic or monophasic, according to the increase in the degrees of steatosis hepatic. The results were statistically significant for the maximum, minimum and average velocities of the portal vein, when a comparison between the non-carrier group and the fatty liver carrier group was performed. Conclusion: Non-alcoholic fatty liver disease causes changes in hepatic hemodynamics, decreasing the maximum, minimum and average velocities of the portal vein, in addition to changes in the wave pattern of the hepatic vein.
