A vasal anomaly in the region of the Vena cava inferior is being described in the corpse of a 25-year-old man. 1. In the course of development the V. subcardinalis has not been joined to the Pars hepatica of the V. cava inferior, which originates from the V. hepatis revehens communis. In our case the Anastomosis intersubcardinalis remains and is subjected to a slight retroaortal displacement to the left. 2. Among the Vv. sacrocardinales the V. sacrocardinalis sinistra, which ought to involute after the sixth embryonal week, has been retained together with the Anastomosis intersacrocardinalis. 3. The Vv. supracardinales are connected with the intersubcardinal anastomosis and the intersupracardinal transversal anastomosis has been retained. 4. The Vv. caudales end in the Anastomosis sacrocardinalis at a point before the Sacrum and the Anastomosis intercaudalis has been retained, too. 5. The caudal section of the right lower cardinal vein in its prerenal part is retained with an anastomosis to the right subcardinal vein. 6. The portal blood of the liver is directly distributed to the atrium dextrum after it has passed through three Vv. hepaticae. The Lig. venosum is intrahepatic and is joined to the Vv. hepaticae. 7. The primitive bilateral-symmetric veinous system of the caudal half of the body continues to exist almost completely.
在一名25岁男性尸体中发现下腔静脉区域存在血管异常。1. 在发育过程中，副主静脉未与起源于肝返总静脉的下腔静脉肝部相连。在我们的病例中，副主静脉间吻合支保留下来，并向左主动脉后略有移位。2. 在骶主静脉中，本应在胚胎第6周后退化的左骶主静脉与骶主静脉间吻合支一起保留了下来。3. 上主静脉与副主静脉间吻合支相连，上主静脉间横向吻合支也保留了下来。4. 尾静脉在骶骨前方汇入骶主静脉吻合支，尾静脉间吻合支也保留了下来。5. 右下主静脉肾前部分的尾段保留，并与右副主静脉有吻合。6. 肝脏的门静脉血在经过三条肝静脉后直接注入右心房。静脉韧带位于肝内，与肝静脉相连。7. 身体后半部原始的双侧对称静脉系统几乎完全保留。
