Portal hypertension is defined as an increase in the pressure gradient between the portal vein and IVC or hepatic veins of 10 to 12 mm Hg or greater. They deliver deoxygenated blood from the liver and other lower digestive organs like the colon, small intestine, stomach, and pancreas, back to the heart; this is done via the IVC. Since the liver serves the important function of filtering blood as it moves from the digestive tract, these veins are particularly important for overall health. Measurements taken at the junction of the right atrium and IVC are not equivalent to the other sites; clinicians should avoid measuring percentage collapse of . The IVC diameter can be measured either close to its entrance to the right atrium or 1 to 2 cm caudal to the hepatic veinIVC junction (approximately 34 cm from the junction of the IVC and the right atrium). Unlike other organs, 75% of the liver blood supply is nutrient dense venous blood, entering into the liver from the portal vein while the remaining oxygenated blood supply enters from the hepatic artery as arterial blood. It is common practice in echocardiography to estimate the right atrial (RA) pressure by examining the inferior vena cava (IVC) size and its response to respiration.
