Percutaneous closure of the patent arterial duct in patients with interrupted inferior caval vein poses a technical challenge. A 12-year-old girl with a patent ductus arteriosus (PDA) and interrupted inferior caval vein is described in this report. The diagnosis of interrupted inferior caval vein and azygos continuation was made in the catheterization laboratory. A catheter was advanced and snared in the descending aorta. An exchange wire was advanced through the catheter and snared in the descending aorta. Then, an Amplatzer TorqVue 2 delivery sheath was advanced over the wire from the venous side and again snared in the descending aorta. An Amplatzer duct occluder (ADO) size 8/6 was advanced through the sheath while still holding the sheath with a snare. The device was opened. The sheath was then unsnared once the aortic disc was completely out. The sheath and the device were pulled back into the duct and the device was successfully implanted. The device was then released and it attained a stable position. An aortic angiogram was performed which showed complete occlusion.
对于下腔静脉中断的患者，经皮闭合动脉导管未闭存在技术挑战。本报告描述了一名患有动脉导管未闭（PDA）和下腔静脉中断的12岁女孩。在导管室诊断为下腔静脉中断和奇静脉延续。将导管推进并套住降主动脉。一根交换导丝通过导管推进并套住降主动脉。然后，将一个Amplatzer TorqVue 2输送鞘沿导丝从静脉侧推进，并再次套住降主动脉。在仍用圈套器固定鞘管的同时，将一个8/6型号的Amplatzer动脉导管封堵器（ADO）通过鞘管推进。装置打开。一旦主动脉盘完全伸出，就松开鞘管。将鞘管和装置拉回到导管中，装置成功植入。然后释放装置，其达到稳定位置。进行主动脉血管造影显示完全闭塞。
