Mathematical Modeling of the Blood Flow in Hepatic Vessels

Resumo

A mathematical model is developed for the blood flow in the vessels connected with the hepatic portal vein. A satisfactory anatomical model of the venous vessels of unpaired organs in the abdominal cavity and in the portal vein basin is constructed and integrated into the general systemic circulation model. Computer experiments are carried out modeling redistribution of venous and arterial blood flows in the presence of portal hypertension in liver fibrosis. The hydrodynamic properties of the blood flow are investigated allowing for anatomical and artificial shuts and their effect on pressure reduction in the portal vein. The calculation results are consistent with clinical data.
