Aneurysms isolated in the iliac artery and measuring more than 3 cm in diameter are associated with an increased rate of rupture and a high mortality rate. The current therapy recommended for such aneurysms is surgical exclusion. Percutaneous exclusion of isolated iliac aneurysms with covered or uncovered stents, however, reduces the morbidity and mortality rates associated with surgery by obviating the need for general anesthesia, avoiding significant blood loss, and reducing in-hospital recuperation time. We report the case of a patient who had an isolated atherosclerotic iliac artery aneurysm that was successfully excluded percutaneously by use of an endovascular prosthesis (WALLSTENT Endoprosthesis) made by Schneider (USA), Inc; Minneapolis, Minn, in conjunction with the Thin-Walled GORE-TEX (polytetrafluoroethylene) Vascular Graft (W.L. Gore & Associates, Inc.; Flagstaff, Ariz). Although various stent devices have been used recently in conjunction with a polytetrafluoroethylene graft to exclude peripheral arterial aneurysms, the self-expandable WALLSTENT has not been used with polytetrafluoroethylene in this fashion and for this purpose until recently. We present herein the technical aspects of endoluminal exclusion of the isolated iliac artery aneurysm with this composite stent-graft.
孤立于髂动脉且直径超过3厘米的动脉瘤，其破裂率和死亡率会增加。目前针对此类动脉瘤推荐的治疗方法是手术切除。然而，使用有覆膜或无覆膜支架经皮排除孤立性髂动脉瘤，通过避免全身麻醉、防止大量失血以及缩短住院康复时间，降低了与手术相关的发病率和死亡率。我们报告了一例患有孤立性动脉粥样硬化性髂动脉瘤的患者，该动脉瘤通过使用美国明尼苏达州明尼阿波利斯市施奈德公司生产的血管内假体（WALLSTENT血管内假体）联合薄壁GORE-TEX（聚四氟乙烯）血管移植物（美国亚利桑那州弗拉格斯塔夫市W.L.戈尔公司）成功经皮排除。尽管最近各种支架装置已与聚四氟乙烯移植物联合用于排除周围动脉动脉瘤，但直到最近，自膨式WALLSTENT尚未以这种方式和用于此目的与聚四氟乙烯联合使用。我们在此介绍使用这种复合支架移植物腔内排除孤立性髂动脉瘤的技术要点。
