Two uncommon anatomical variations of the left renal vein were found on dissected specimens: a circumaortic venous ring and a retro-aortic bifid left renal vein. The first anomaly results from a persistence of the embryonic renal venous collar. The second one would be related to a particular pattern of left inferior vena cava. Both abnormalities have to be known for they may be undetected or be misleading in imaging. Other clinical implications are also considered.
主动脉周围静脉环和主动脉后双叉左肾静脉。第一种异常是由于胚胎肾静脉环持续存在所致。第二种异常可能与左下腔静脉的特定模式有关。这两种异常情况都必须了解，因为它们在影像学检查中可能未被发现或产生误导。还考虑了其他临床意义。
