The purpose of this study was to determine the long-term results of a 7-year follow-up of endovascular aneurysm repairs (EVARs) of abdominal aortic aneurysms (AAAs) using custom-made stent grafts (SGs).
We performed a retrospective review of 17 patients (14 males, 3 females; mean age: 74.3 +/- 7.9 years; range: 53-85) undergoing EVAR of infrarenal aortic aneurysms at our institution from April 2000 to August 2006. The primary and secondary clinical success rates were 82.4% (14/17) and 100% (17/17). The initial and short-term clinical success rates were 100%. During follow-up (mean: 38.8 +/- 35.9 months; range: 0.8-90 months), 4 patients died, but there was no aneurysm-related death. In 2 patients, additional surgery was performed. The long-term clinical success rate was 83.3% (5/6). In the Kaplan-Meier curve, the 1- and 5-year survival rates were 55.0% and 45.8%, respectively.
The initial and short-term clinical success rates were 100%; regarding the short-term, aneurysm-related death could be avoided. However, during long-term follow-up, aneurysm-related events did occur. Follow-up should be performed over a long period.
本研究的目的是确定使用定制支架型人工血管（SG）对腹主动脉瘤（AAA）进行血管腔内动脉瘤修复术（EVAR）7年随访的长期结果。
我们对2000年4月至2006年8月在本机构接受肾下腹主动脉瘤EVAR的17例患者（14例男性，3例女性；平均年龄：74.3±7.9岁；范围：53 - 85岁）进行了回顾性研究。主要和次要临床成功率分别为82.4%（14/17）和100%（17/17）。初始和短期临床成功率为100%。在随访期间（平均：38.8±35.9个月；范围：0.8 - 90个月），4例患者死亡，但无动脉瘤相关死亡。2例患者接受了额外手术。长期临床成功率为83.3%（5/6）。在Kaplan-Meier曲线中，1年和5年生存率分别为55.0%和45.8%。
初始和短期临床成功率为100%；就短期而言，可避免动脉瘤相关死亡。然而，在长期随访期间，确实发生了动脉瘤相关事件。应进行长期随访。
