Hepatic vein spectral broadening

WebHepatic veins (HV) are large veins that drain blood into the right atrium (RA) through the inferior vena cava (IVC). There are three major hepatic veins, named the right hepatic vein, middle hepatic vein and left hepatic vein. The hepatic veins appear in ultrasound as thin-walled tubular anechoic structures enclosed by hepatic parenchyma. Alterations in the normal hepatic venous Doppler waveform often indicate cardiac dysfunction, although it may also reflect disease of the … Meer weergeven 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 gradients. Multiple terms have … Meer weergeven The normal periodic hepatic vein waveform is typically described in four parts: 1. a wave: atrial contraction 1.1. coinciding … Meer weergeven
