A nineteen-month-old girl was taken up for patent ductus arteriosus (PDA) device closure. A diagnostic catheter from the right femoral venous access entered the superior vena cava (SVC), through the azygos vein suggesting interruption of inferior vena caval with azygos continuity. Therefore, the PDA device was closed from the right jugular venous access. However, a postprocedure echocardiogram (echo) showed a patent inferior vena caval connection into the right atrium. An angiogram from femoral veins showed communication between the iliac veins and the azygos system, in addition to normal drainage into the inferior vena cava (IVC). Congenital communication between the iliac veins and the azygos system can mimic IVC interruption. An attempt to theoretically explain the embryological origin of the communication has been made.
一名19个月大的女童因动脉导管未闭（PDA）接受封堵术。一根诊断导管经右股静脉进入上腔静脉（SVC），通过奇静脉，提示下腔静脉中断伴奇静脉连续性。因此，经右颈静脉途径封堵PDA装置。然而，术后超声心动图（echo）显示下腔静脉与右心房之间存在未闭连接。股静脉造影显示髂静脉与奇静脉系统之间存在交通，此外还有正常的下腔静脉（IVC）引流。髂静脉与奇静脉系统之间的先天性交通可模拟IVC中断。本文尝试从理论上解释这种交通的胚胎学起源。
