Endovascular treatment of abdominal aortic aneurysms is a rapidly evolving technique that has gained broad acceptance in the treatment of patients with abdominal aortic aneurysms.
A review of the English literature was done to determine the short- and long-term outcomes of endovascular repair of abdominal aortic aneurysms. Reports of complications such as endoleak, graft migration, graft limb occlusion, aneurysm rupture, and aneurysm enlargement were evaluated.
Short-term results of endovascular repair of abdominal aortic aneurysms are excellent. The necessity for open conversions is less than 5%. The cumulative risk of aneurysm rupture is approximately 1% per year. The coverall incidence of graft limb occlusion was 2.8% in the follow-up period. The cumulative risk for a secondary procedure was 12% at 1 year, 24% at 2 years, and 35% at 3 years. Moderate and severe neck angulation was associated with an increased incidence of adverse events in the follow-up period. Endografts have the potential to become infected and develop aortoduodenal fistula. The treatment of ruptured aneurysms with endovascular grafts has been successful and a technique that is increasingly used.
Endovascular treatment of abdominal aortic aneurysm is an effective technique with excellent short-term results. The long-term results remain to be determined. Ongoing surveillance is necessary to avoid late complications of aneurysm rupture.
腹主动脉瘤的血管内治疗是一项快速发展的技术，已在腹主动脉瘤患者的治疗中获得广泛认可。
对英文文献进行综述，以确定腹主动脉瘤血管内修复的短期和长期结果。评估了诸如内漏、移植物移位、移植物肢体闭塞、动脉瘤破裂和动脉瘤增大等并发症的报告。
腹主动脉瘤血管内修复的短期结果极佳。开放转换的必要性小于5%。动脉瘤破裂的累积风险约为每年1%。随访期间移植物肢体闭塞的总体发生率为2.8%。二次手术的累积风险在1年时为12%，2年时为24%，3年时为35%。中度和重度颈部成角与随访期间不良事件发生率增加相关。血管内移植物有发生感染并形成主动脉十二指肠瘘的可能。用血管内移植物治疗破裂性动脉瘤已取得成功，且该技术的应用日益广泛。
腹主动脉瘤的血管内治疗是一项有效的技术，短期结果极佳。长期结果仍有待确定。持续监测对于避免动脉瘤破裂的晚期并发症很有必要。
