Other things that can block the hepatic veins include: A blocked hepatic vein can damage your liver and lead to a condition called Budd-Chiari syndrome. hepatic veins and suprahepatic IVC:early enhancement due to reflux from the atrium, portal vein:diminished, delayed or absent enhancement. The inferior vena cava (IVC) is the largest vein of the human body. The hepatic veins carry blood to the inferior vena cavathe largest vein in the bodywhich then carries blood from the abdomen and lower parts of the body to the right side of the heart. 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 .

Venous: Etiology and manifestations for varicose veins, deep vein thrombosis. The IVC diameter is altered with volume status and respiration, with higher IVC diameter during expiration than inspiration. nance imaging showed normal hepatic vein and inferior vena cava without obstruction, but dilated PV. Saunders. A dilated IVC (>1.7 cm) with normal inspiratory collapse (>50%) is suggestive of a mildly elevated RA pressure (610 mm Hg). Symptoms usually result from abdominal distention. 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). Specific vascular lesions may occur in the hepatic artery, hepatic vein, or portal vein. Gore RM, Mathieu DG, White EM et-al. Wilson disease is present at birth, but symptoms usually start between ages 5 and 35.

Factors Increasing Central Venous Pressure. If the pressure in the pulmonary artery is greater than 25 mm Hg at rest or 30 mmHg during physical activity, it is abnormally high and is called pulmonary hypertension.
