Study of Variations in the Diameter (Caliber) of Right Hepatic Vein in Male Cadaveric Livers of South Indian Population

The diameter of right hepatic vein is measured from the 25 Male cadaveric livers by Vernier Caliper. A) Diametric Mean Value of right hepatic vein near Inferior Venacava is 1.88 cm ± 0.23(SD = 0.57), b) Diametric mean value of the right hepatic vein terminating at inferior venacava was 0.98 ±0.3(SD = 0.82). c) Diametric mean value at the depth of 2cm in inferior venacava is 2.25cm ± 0.8 (SD = 0.19). d) Diametric mean value of tributaries of right hepatic vein is 3.1cm ± 0.43 (SD = 1.77). This diametric (caliberic) study will certainly enable the surgeon for planned surgeries and minimize the risk of complication during the resection and transplantation of liver because right hepatic vein present in the right portal scissura in most of the livers. Moreover these diametric study will have clinical and radiological importance as increased diameter was observed in non-alcoholic fatty liver (1) and in portal hypertension in Budd-Chi- ari Syndrome (2).
