  • Title: [Evaluation of portal circulation in healthy subjects with duplex scanning before and after meal].

    Journal: Vestn Ross Akad Med Nauk; 1994; (6):16-9. PubMed ID: 7522694.
    Abstract:
    Duplex scanning was used to functionally assess the arterial and venous vascular bed in the portal circulatory system in 11 healthy persons aged 17 to 22 years before and after taking the food containing normal levels of calories. A circulatory response was studied in the celiac trunk, superior mesenteric artery, splenic and portal veins. The normal values of the diameter, linear and volumetric blood flow velocities of the vessels under study were defined. There was their increased velocity of arterial and venous flows. A nevous response to a meal was ahead of an arterial one and the increase in blood flow in the celiac trunk occurred more rapidly than in the superior mesenteric artery. It is concluded that duplex scanning is an informative and reliable tool in the study of blood flow in the portal circulatory system.
