ABSTRACT
50 dissections of the human inferior V. cava have been performed in order to measure its right renal vein - diaphragm, retrohepatic, and suprahepatic segments. We conclude that some individual parameters as skin type, age, height, weight did not influence the magnitude of the studied segments. The average measurements of the different parameters proposed for the inferior V. cava are: 1. The distances between the right renal vein and the diaphragm and between the right renal vein and the right atrium are 113.94 mm and 135.16 mm, respectively; 2. the length of the retrohepatic portion of the inferior V. cava and the suprahepatic one were 78.34 mm and 19.34 mm respectively; 3. the valve of the inferior V. cava is present in 46% of the observations; its length and width averages are 31 mm and 10.22 mm, respectively.
