ABSTRACT

144 normal adult livers were studied anatomically. The length of the retrohepatic segment of the inferior vena cava was 6.6 centimeters and was totally enclosed by liver substance in 12.5% of cases. Altogether 1,581 ostia venae hepaticae were found, on average 11 per liver and these were classified as large, medium, small or minimum. The localisation of these openings was studied according to the division of interior wall of the retrohepatic segment of IVC into 16 areas.
