An impediment to hepatic venous outflow anywhere from the small hepatic venules to the cavoatrial junction because of a wide spectrum of etiologies results in Budd-Chiari syndrome, also known as hepatic venous outflow tract obstruction (HVOTO). 2016. 3. When a blockage occurs of these veins and blood is unable to drain from the liver, a rare disease, Budd-Chiari syndrome can result. These veins can also develop hypertensionhigh blood pressure in these veinscan also arise in cases of chronic liver disease. More dilated hepatic veins often present a "deer-horn" appearance. The IVCs function is to carry the venous blood from the lower limbs and abdominopelvic region to the heart. The inferior vena cava (IVC) is the largest vein in the body, draining blood from the abdomen, pelvis and lower extremities. The condition may be discovered when tests are done for other reasons. The 2008 ACEP Policy Statement on Emergency Ultrasound Guidelines includes the evaluation of intravascular volume status and estimation of central venous pressure (CVP) based on sonographic examination of the inferior vena cava (IVC). Ultrasound evaluation of the inferior vena cava (IVC) provides rapid, noninvasive assessment of a patients hemodynamic status at the bedside. It also increases pressure on these veins, and fluid may build up in the abdomen. Passive hepatic congestion: cross-sectional imaging features.
