The established therapy for symptomatic, expanding abdominal aortic aneurysms is open surgical replacement with an artificial graft. Over the last several years, there has been increasing enthusiasm for the use of endoluminal graft prostheses to exclude abdominal aortic aneurysms. However, even with rapid advances in stent graft technology, certain problems (i.e., large profile of the devices, risk of thromboembolism, poor flexibility, endoleak formation, and side-branch occlusion) have yet to be overcome. We present the case of an 85-year-old woman with multiple comorbid illnesses who underwent endoluminal repair of her expanding abdominal aortic aneurysms. We used bare-metal Wallstent endoprostheses (Schneider, Inc.; Minneapolis, Minn) in combination with endovascular coils (Cook, Inc.; Bloomington, Ind). The bare-metal Wallstent endoprostheses were used because the patient had severely narrowed iliac arteries and a large side branch originating from the aneurysm. The procedure was technically successful, and there was no significant morbidity. Follow-up angiographic evaluation at 6 months revealed no evidence of vascular enlargement; it also revealed preservation of important side branches, and spontaneous thrombosis of the aneurysms.
对于有症状的、不断扩大的腹主动脉瘤,既定的治疗方法是采用人工血管进行开放手术置换。在过去几年中,人们越来越热衷于使用腔内移植物假体来隔绝腹主动脉瘤。然而,即使支架移植物技术取得了快速进展,某些问题(如装置外形较大、血栓栓塞风险、柔韧性差、内漏形成和侧支闭塞)仍有待克服。我们报告了一例85岁患有多种合并症的女性患者,她接受了扩张性腹主动脉瘤的腔内修复术。我们使用了裸金属Wallstent内支架(施奈德公司;明尼阿波利斯,明尼苏达州)并结合血管内弹簧圈(库克公司;布卢明顿,印第安纳州)。使用裸金属Wallstent内支架是因为该患者髂动脉严重狭窄且动脉瘤有一个大的侧支。手术在技术上取得成功,且无明显并发症。6个月时的随访血管造影评估显示没有血管扩大的迹象;还显示重要侧支得以保留,且动脉瘤出现自发性血栓形成。
