Conclusion: A dilated IVC without collapse with inspiration is associated with worse survival in men independent of a history of heart failure, other comorbidities, ventricular function, and pulmonary artery pressure. If this happens, patients could have a heart attack, pulmonary embolism, or stroke. Sometimes one or more hepatic veins can narrow or get blocked, so blood cant flow back to your heart. The vessel contracts and expands with each respiration. Passive hepatic congestion, also known as congested liver in cardiac disease, describes the stasis of blood in the hepatic parenchyma, due to impaired hepatic venousdrainage, which leads to the dilation of central hepatic veins and hepatomegaly. On the bottom end of the liver are the organs unusual double blood supplies. I am currently continuing at SunAgri as an R&D engineer. More dilated hepatic veins often present a "deer-horn" appearance. It is caused most often by cirrhosis (in North America), schistosomiasis (in endemic areas), or hepatic vascular abnormalities. Suppurative thrombophlebitis of the IVC is even a more uncommon subtype of IVC thrombosis and is mostly associated with IVC filters or venous catheters.

Our website is not intended to be a substitute for professional medical advice, diagnosis, or treatment. The portal vein (which is rich in nutrients and relatively high in oxygen) provides two thirds of blood flow to the liver. The IVC diameter is affected by right heart function, as well as conditions like IVC aneurysm or Budd-Chiari syndrome (BCS), which directly or indirectly increase the volume of the blood in the right heart or increase the back pressure on the systemic circulation ultimately leading to IVC dilation [2,3]. Most commonly, these veins can be impacted in cases of cirrhosis, in which there is scarring of the liver tissue due to a range of diseases, including hepatitis B, alcohol use disorder, and genetic disorders, among other issues. In these cases, blood flow is slowed down and these veins can develop high blood pressure (hypertension), which is potentially very dangerous. This condition is characterised by bacterial thrombophlebitis in the hepatic venous opening of IVC which on resolution could form a membrane or a stenosis or a thick obstruction followed by collaterals.

Variations to the anatomy of the hepatic veins are not uncommon and occur in approximately 30% of the population. Prolonged exposure to elevated hepatic venous pressure may lead to liver fibrosis and cirrhosis. Deep venous thrombosis (DVT, 8/8) and pulmonary embolism (5/8 . Abstract. 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. FOIA 2014 Feb;27(2):155-62. doi: 10.1016/j.echo.2013.09.002. 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. Conclusions: Measurements of respiratory variation in IVC collapse in healthy volunteers are equivalent at the level of the left renal vein and at 2 cm caudal to the hepatic vein inlet. Typical structural features of the athlete's heart as defined by echocardiography have been extensively described; however, information concerning extracardiac structures such as the inferior vena cava (IVC) is scarce. The main hepatic veins are not visualised; however, a dilated accessory inferior right hepatic vein (AIRHV) is seen.
