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. Check for errors and try again. The main hepatic veins are not visualised; however, a dilated accessory inferior right hepatic vein (AIRHV) is seen. Other ancillary findings in such cases include dilated IVC (diameter >2.5 cm) and hepatic veins with abnormal spectral waveform [13]. A dilated IVC (>1.7 cm) with normal inspiratory collapse (>50%) is suggestive of a mildly elevated RA pressure (610 mm Hg). liver enhancement pattern:reticulated mosaic pattern of low signal intensity linear markings which become more homogenous in 1-2 minutes.

Mild right upper quadrant abdominal pain has been reported to be the result of hepatomegaly and stretching of the hepatic Glisson capsule 1. 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]. IVC variants and dilated collateral veins can be mistaken for malignancy. This site needs JavaScript to work properly. The hepatic outflow obstruction usually occurs at the level of the inferior vena cava (IVC); the hepatic veins; and, depending on the classification and n. Plethora of inferior vena cava (IVC) - Dr. Johnson Francis, DM Multiple regression analysis showed the impact of VO(2) max, cardiac index, and right ventricular and left ventricular end-diastolic dimensions on IVC diameter. Relatively larger in size, there are three major hepatic veinsthe left, middle, and rightcorresponding to the left, middle, and right portions of the liver. These structures originate in the livers lobule and also serve to transport blood from the colon, pancreas, small intestine, and stomach. In most cases, the right hepatic vein will be whats affected. Epub 2021 Jun 19. We report the first case series of IVCT observed in Taiwan with a brief literature review. Read our, Linear endoscopic ultrasound evaluation of hepatic veins.
