Abstract：
Chronic venous insufficiency, caused by inferior vena cava occlusion, can lead to thromboembolic complications and tissue loss. We present two cases of azygos vein stenting (AVS) in which vena cava recanalization techniques were exhausted. In the first case, the left iliac vein and vena cava were recanalized and stented; however, the right iliac vein had been previously resected and required AVS. Conventional recanalization attempts from the right and left iliac systems failed in the second patient with congenital inferior vena cava occlusion; therefore, AVS was chosen to establish in-line drainage.
摘要：
慢性静脉功能不全,由下腔静脉阻塞引起的，可导致血栓栓塞并发症和组织丢失。我们介绍了两例奇静脉支架置入术（AVS），其中腔静脉再通技术已用尽。在第一种情况下,左髂静脉和腔静脉再通并置入支架；然而，右髂静脉先前已切除,需要AVS.在第二例先天性下腔静脉闭塞的患者中，常规的右和左髂系统再通尝试失败；因此，选择AVS来建立在线引流。
