The stimulus for the present investigation arose from the frequent occurence in routine laboratory observations of variant types of the vena cava posterior. It was also noted at the same time that the relation of the renal veins to the various definitive patterns of vena cava posterior, and the relation of the renal arteries to the abdominal aorta were not uniform. An examination of the literature reveals no record of any work involving the tabulating of definitive patterns of renal arteries and veins. The purpose of the present work is twofold: first, to determine whether the typical pattern of renal veins bears the same relationship to the vena cava when the vena cava posterior is atypical as when the vena cava is typical (normal); secondly, to catalogue the patterns of renal arteries and show their relationship to the abdominal aorta.
