Seven-year results of endovascular aneurysm repairs of abdominal aortic aneurysms with custom-made stent grafts.

BACKGROUND

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).

METHODS AND RESULTS

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.

CONCLUSION

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.
