right hepatic veins

right he·pa·tic veins

veins draining much of the right lobe of the liver (posterior lateral segment [VI] and right anterior lateral segment [VI] and the lateral parts of the posterior and inferior anterior medial segments [V and VII]) that merge to form a single or sometimes double trunk, draining into the right side of the suprahepatic portion of the inferior vena cava (between the superior surface of the liver and the diaphragm); when single, it is the largest vein of the liver.
Synonym(s): venae hepaticae dextrae [TA]

Anatomical variations in the pattern of the right hepatic veins draining the posterior segment of the right lobe of the liver.
3) The right portal fissure separates segment V from segments VI-VII; the fissure plane inclines 60 degrees to the right in relation to the sagittal plane of the liver; it contains the right hepatic vein, the right middle hepatic vein (5 %) and the right lower hepatic vein (61 %); its trajectory on the diaphragmatic surface of the liver starts from an intermediate point between the right edge of the gallbladder and the right angle of the liver to the right edge of the inferior vena cava, describing a wide curve of right convexity.
Numerous anatomical variations of the hepatic veins (HV) have been found, especially the presence of accessory right hepatic veins (aRHVs) in the right hemiliver.
Anatomical variations in the pattern of the right hepatic veins: possibilities for type classification.
The left, middle, and right hepatic veins were cannulated and the free hepatic vein pressure (FHVP) and the wedged hepatic venous pressure (WHVP) were assessed.
RESULTS: Angle between middle and right hepatic veins were measured.
Adult LDLT is safely achieved with better outcome to recipients and donors by recovering the right lobe without MHV, provided that significant MHV tributaries (segments V, VIII more than 5 mm) are reconstructed, and any accessory considerable inferior right hepatic veins (IRHVs) or superficial RHVs are anastomosed.
There were two nodules at the junction of the middle and right hepatic veins and one on the surface of segment IV B.
The CT scan that was acquired 70 seconds after the start of IV contrast administration showed a contrast agent deposit with a blood-contrast level in the dependent portion of the superior vena cava (Figure 1A) and the inferior vena cava (Figure 1B), dense opacification of the right portal and right hepatic veins (Figure 1C), contrast material pooling in the right renal parenchyma (Figure 1D), and a nonenhanced small abdominal aorta (Figure 1B, C, and D).
The right fissure contained the upper (A12.3.09.006), middle, and lower right hepatic veins; the main fissure contained the intermediate vein (A12.3.09.007); the umbilical fissure did not contain the left hepatic vein (A12.3.09.008), this vein has intrasegmental pathway in segments III and II.
The segment V (yellow) limits ahead with the inferior border of the liver, behind the inferior vena cava, medially with the main portal fissure containing the intermediate hepatic vein and the medial edge of the segment IV, laterally with the right fissure containing the right hepatic veins and the medial edge of the segments VI and VII.
