Abstract:
Background. Complicated evolutionary forms of liver cirrhosis are particularly caracterized
by damage to the hepatic arterial circuit. The hepatic artery represents the nutritional
vascularization, representing the branch of the celiac trunk that propels O2-enriched blood
to the liver.
Objective(s). Evaluation of blood flow in the large-caliber arterial networks of the liver by
Doppler quantification in liver cirrhosis.
Materials and methods. Subjects of the study were 62 patients with liver cirrhossis – 46
men, 16 women, mean age - 39±0.21 years. The linear parameters studied by Doppler
quantification were calculated in the hepatic artery, portal vein, splenic vein and superior.
Results. The volume of blood flow velocity in the hepatic artery was 269±115 ml/min. The
volumetric flow rate in the portal vein varied between 578±31 ml/2 ml/min and 324±15.6 ml/min, constituting approximately 1000-1200 ml/min. In the splenic vein the volume
velocity ranged from - 157±0,4 to 366±12 ml/min. A linear increase in blood flow by 70%
was observed. Superior mesenteric vein – normal flow volume is 194±25 ml/min. As the
pathology progressed, the flow volume also increased from 785±0,5 ml/min to 979±138
ml/min.
Conclusion(s). Acceleration of blood flow in the hepatic artery represents informative
hemodynamic parameters that secondarily invoke the reduction of elasticity and tone of
large veins, the decrease in filling of small and medium caliber arteries of the liver.
