IVC is the inferior vena cava which passes behind the intestines and conveys blood from the lower body to the heart. 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. The vitelline vein contributes to the hepatic segment of the IVC. IVC dilatation in the absence of any cardiac involvement is termed as idiopathic. Causes are most often systemic: Impaired hepatic read more ; focal ischemia can cause hepatic infarction or ischemic cholangiopathy Ischemic Cholangiopathy Ischemic cholangiopathy is focal damage to the biliary tree due to disrupted flow from the hepatic artery via the peribiliary arterial plexus.

Obstruction of inferior vena caval orifice by giant left atrium in patients with mitral stenosis. An ECHO can cause some pain if a liquid contrast is used, it is radioactive isotope and some people have an allergic reaction to it. It is caused most often by cirrhosis (in North America), schistosomiasis (in endemic areas), or hepatic vascular abnormalities. Clots of the hepatic veins lead to a rare disorder called Budd-Chiari syndrome. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). Isolated dilatation of the inferior vena cava. Careful review of the echocardiographic images showed nodular thickening of the pericardium in the AV groove, without significant thickening of the whole pericardium. A dilated IVC (>2 cm) has been found to indicate high RA pressure, particularly when there is no collapse during inspiration. 3. rupture = blow hole through heart wall (b/c MI causes thinning of the wall) biggest danger w/in 2 weeks of MI. {"url":"/signup-modal-props.json?lang=gb"}, Di Muzio B, Weerakkody Y, Rock P, et al.
