Expandable metallic stent was successfully introduced to 5 patients including idiopathic obstruction of the hepatic portion of the inferior vena cava (1 case), superior vena cava obstruction from metastatic lymphnodes swelling (2 cases) and IVC obstructions from liver metastases or lymphnodes metastases (2 cases). The obstructions were 4-14 cm long in the case of venous obstructions due to lymphnodes metastases and 2 cm long in the case of idiopathic hepatic IVC obstruction. In all cases, the stents were introduced by using 12-16 Fr catheter percutaneously without any complications. The stent used was connected up to 7 pieces by using wire struts depending length of the obstructions. However the stents connected more than 5 pieces were difficult to advance through the catheter. The patients who had been treated with stents had been free from hazardous complications such as lower extremity swelling, and pain.
可扩张金属支架成功应用于5例患者，包括下腔静脉肝段特发性梗阻（1例）、转移性淋巴结肿大导致的上腔静脉梗阻（2例）以及肝转移或淋巴结转移导致的下腔静脉梗阻（2例）。因淋巴结转移导致静脉梗阻的病例中，梗阻长度为4 - 14厘米，特发性肝下腔静脉梗阻病例中梗阻长度为2厘米。所有病例均通过经皮使用12 - 16 Fr导管置入支架，无任何并发症。根据梗阻长度，使用金属丝支架将支架连接多达7个。然而，连接超过5个的支架很难通过导管推进。接受支架治疗的患者未出现下肢肿胀和疼痛等严重并发症。
