WebAnatomy. Although the liver has a dual blood supply, the hepatic veins provide the sole route of egress for blood exiting the liver. The segmental anatomy of the liver as defined by the French surgeon Claude Couinaud [] divides the liver into eight segments, with portal vein branches at the center and hepatic veins at the periphery.The right, middle, and left … Alterations in the normal hepatic venous Doppler waveform often indicate cardiac dysfunction, although it may also reflect disease of the hepatic parenchyma and/or vasculature. The consequent hemodynamic … See more The shape of the hepatic vein spectral Doppler waveform is primarily determined by pressure changes in the right atrium, or more exactly the blood flow resulting from the resultant pressure … See more The normal periodic hepatic vein waveform is typically described in four parts: 1. a wave: atrial contraction 1.1. coinciding with the "p wave" on the electrocardiogram, contraction elevates pressure within the … See more halloween diy outdoor decorations witches
