Abstract

PURPOSE
The AFX2 endograft is a unibody, bifurcated stent graft that can be used to lower complications in certain patients. In this study, we retrospectively reviewed consecutive cases in which the AFX2 system was used to overcome the challenges of narrow distal aorta, as well as to reduce procedure time and contrast medium dose. Furthermore, we compared the results with matched patients treated using the Endurant II endograft system.
MATERIALS AND METHODS
This was a retrospective observational study of nine patients with abdominal aortic aneurysm (AAA) who underwent endovascular aneurysm repair (EVAR) using the AFX2 device between June 2017 and April 2018 at Seoul National University Hospital. The patients had narrow distal aorta (n=3), reversed tapered neck (n=1), iliac artery aneurysm (n=2), chronic kidney disease patients (n=2), and impending rupture (n=1). Seven matched patients were treated using the Endurant II graft.
RESULTS
In the AFX2 group, the mean procedure time was 87.2 minutes, mean blood loss volume was 157.7 mL, and mean volume of contrast medium used was 48.3 mL. In the Endurant II group, the mean procedure time was 140.0 minutes, mean blood loss volume was 175.0 mL, and mean volume of contrast medium used was 119.3 mL.
CONCLUSION
Our preliminary experiences with selected AAA patients treated using the AFX2 endovascular repair system showed good outcomes compared with similar patients treated using the Endurant II system. Therefore, the AFX2 may be a good option to perform EVAR in patients of advanced age who have chronic kidney failure or narrow distal aorta.
