Two patients with infrahepatic interruption of the inferior vena cava (IVC) with azygos (hemiazygos) continuation were examined ultrasonographically and the findings compared to seven normal studies. Pathognomonic ultrasonographic features of this anomaly are easily demonstrated and include absence of the IVC at the level of the liver and independent drainage of the confluence of hepatic veins into the right atrium. Conventional venography can now be replaced by ultrasonic examination to establish this diagnosis. The embryology, anatomy and clinical implications of this entity are discussed.
对两名患有下腔静脉肝下中断并奇静脉（半奇静脉）延续的患者进行了超声检查，并将结果与七项正常研究进行了比较。这种异常的特征性超声表现很容易显示出来，包括肝脏水平下腔静脉缺如以及肝静脉汇合处独立引流至右心房。现在，超声检查可以取代传统静脉造影来做出这一诊断。本文讨论了该实体的胚胎学、解剖学和临床意义。
