To evaluate the feasibility of stent-grafts for treatment of isolated iliac artery aneurysms (IAAs).
Nine IAAs in eight patients were treated with transluminally placed endovascular stent-grafts. All patients were men (median age, 72 years). In three, the aneurysm involved both the common and internal iliac arteries. In one, common and external iliac arteries were involved. The other aneurysms involved only the common iliac artery. Two aneurysms were treated with balloon-expandable stents covered with polytetrafluoroethylene (PTFE) graft material, three were treated with self-expanding Z-stents covered with a woven polyester graft, and four were treated with self-expanding Z-stents covered with PTFE.
Transluminal placement of the stents was successful in all patients with thrombosis of the aneurysms. There were no distal thromboembolic events, deaths, or infections. The median follow-up period was 8.5 months.
Initial results suggest that transluminal stent-graft placement for treating isolated IAAs is a safe and effective alternative to surgery in selected patients. Long-term follow-up data are needed before this approach can be recommended for the primary treatment of IAAs.
评估支架型人工血管治疗孤立性髂动脉瘤（IAA）的可行性。
8例患者的9个IAA接受了经皮腔内放置的血管内支架型人工血管治疗。所有患者均为男性（中位年龄72岁）。3例患者的动脉瘤累及髂总动脉和髂内动脉；1例累及髂总动脉和髂外动脉；其他动脉瘤仅累及髂总动脉。2个动脉瘤采用球囊扩张式支架，覆以聚四氟乙烯（PTFE）移植材料治疗；3个采用自膨式Z形支架，覆以编织聚酯移植材料治疗；4个采用自膨式Z形支架，覆以PTFE治疗。
所有患者经皮腔内放置支架成功，动脉瘤均形成血栓。无远端血栓栓塞事件、死亡或感染发生。中位随访期为8.5个月。
初步结果表明，对于部分患者，经皮腔内放置支架型人工血管治疗孤立性IAA是一种安全有效的手术替代方法。在推荐该方法作为IAA的主要治疗方法之前，需要长期随访数据。
