What is prominent IVC and hepatic veins? Anything that increases right atrial pressure will cause a subsequent increase in pressure inside the IVC resulting in dilation. RA size is prognostic of adverse outcomes in PAH,6 in addition to other cardiovascular conditions, such as heart failure with reduce ejection fraction and RV dysfunction. Elevated hepatic venous pressure and a decrease in hepatic venous flow cause hypoxia in hepatic parenchyma, and eventual diffuse hepatocyte death and fibrosis. The middle hepatic vein is the longest. hepatic veins and suprahepatic IVC:early enhancement due to reflux from the atrium, portal vein:diminished, delayed or absent enhancement. The hepatic artery may be occluded Hepatic Artery Occlusion Causes of hepatic artery occlusion include thrombosis (eg, due to hypercoagulability disorders, severe arteriosclerosis, or vasculitis), emboli (eg, due to endocarditis, tumors, therapeutic read more . Torabi M, Hosseinzadeh K, Federle MP. It divides the liver into the right and left lobes. Why should the patient perform a sniff?

The inferior vena cava carries deoxygenated blood from your liver and the lower half of your body to the right side of your heart. On the bottom end of the liver are the organ's unusual double blood supplies. The hepatic veins drain deoxygenated blood from the liver to the inferior vena cava (IVC), which, in turn, brings it back to the right chamber of the heart. The most common cause is cirrhosis (chronic liver failure). The right atrial cavity area is 21.0cm during systole The inferior vena cava appears dilated measuring 2.20cm.The vessel collapses with inspiration.The tricuspid valve is normal.There is trivial tricuspid regurgigation.Regurgitant velocity is 311.0cm/s and estimated RV systolic pressure is 43mmHg consistent with mild pulmonary hypertension."
