[Left caudal vena cava: report of a case]
Abstract:
The infrarenal part of the vena cava inferior running at the left side of the abdominal aorta has been observed in a 70 years old caucasian man without any other anomaly in the position of the abdominal viscera. This atypical vascular pattern was associated with the persistence of a rudimentary right inferior vena cava corresponding to the right supracardinal vein. The embryonic origin of this anatomical variation and its clinical importance are discussed.
