Each hepatic vein can have two or more branches inside the liver. All forms of heart disease (congenital or acquired) are linked to passive hepatic congestion. Inferior Vena Cava may appear congested when its dilated without any respiratory variation collapsed with very small diameter through the respiratory cycle, or compliant and vary through respiratory cycle. If this happens, patients could have a heart attack, pulmonary embolism, or stroke. The IVC diameter is altered with volume status and respiration, with higher IVC diameter during expiration than inspiration.

Created for people with ongoing healthcare needs but benefits everyone. Fifty-eight top-level athletes and 30 healthy members of a matched control group Congenital thrombosis of the IVC is often asymptomatic which is caused by well-developed collaterals. Blood leaves the liver through the hepatic veins. Although the liver has a dual blood supply, the hepatic veins provide the sole route of egress for blood exiting the liver. The IVC diameter is altered with volume status and respiration, with higher IVC diameter during expiration than inspiration. Unable to process the form. The superior vena cava carries blood from the head, neck, arms, and chest. Portal venous shunts are abnormal communications between portal and systemic venous systems (portosystemic shunts), or between the PVS and the hepatic artery (arterioportal shunts). Careers. Clinical findings in these patients are dominated by those of right-sided heart failure. One is the hepatic artery, which brings in oxygen-rich blood from the heart. The abdominal CT showed prominent dilatation of the IVC and hepatic vein with no evidence of liver disease such as cirrhosis, hepatocellular carcinoma or Budd-Chiari syndrome. We report the first case series of IVCT observed in Taiwan with a brief literature review. "Hepatic" means relating to the liver. Tumors that compress the SVC, such as lung cancer, are generally radiosensitive [12]. All forms of heart disease (congenital or acquired) are linked to passive hepatic congestion.
