Hepatology. 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].
