They tend to be saccular and multiple. 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]. Inferior vena cava (IVC) is normally 1.5 to 2.5 cm in diameter (measured 3 cm from right atrium). The main hepatic veins are not visualised; however, a dilated accessory inferior right hepatic vein (AIRHV) is seen. Macroscopically CT and MRI are able to depict cirrhotic changes as non-specific findings. In addition, multifocal, lobulated, infiltrative, hypoattenuating lesions were also detected (B, arrowheads).

However, the associated complications and mortality may be severe. These clinical manifestations of constrictive pericarditis are similar to those due to a cardiomyopathy. Indeed, it is the only thing that ever has.". IVC variants and dilated collateral veins can be mistaken for malignancy. A rare consequence of inferior vena cava thrombosis is cauda equina syndrome. 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. The vessel contracts and expands with each respiration. The implantation of the IVC filter involves a local anesthetic and numbing medication injected in your skin in the area that the IVC filter will be inserted, preventing discomfort during the surgery. Passive hepatic congestion is a well-studied result of acute or chronic right-sided heart failure. Inferior vena cava syndrome ( IVCS) is a very rare constellation of symptoms resulting from either an obstruction, or stenosis of the inferior vena cava. The IVC is a thin-walled compliant vessel that adjusts to the bodys volume status by changing its diameter depending on the total body fluid volume. Zakim D, Boyer TD.
