Endovascular treatment of complex abdominal aortic aneurysms by combining different types of endoprostheses

Purpose To describe an off-the-shelf method for the treatment of abdominal aortic aneurysms with hostile (large, >30 mm) neck and/or small (<20 mm) aortic bifurcation. Case report We describe five patients with large aortic necks and/or small aortic bifurcations, which were treated by combining an AFX endoprosthesis with a Valiant Captiva endograft, and additional proximal endoanchors when deemed necessary. Initial technical success was 100%. Follow-up ranged from 228 to 875 days. One patient suffered a type 1A and 1B endoleak at 446 days follow-up, which were successfully treated by endovascular means. Conclusion Combining the AFX and Valiant Captiva endografts is an off-the-shelf solution for treatment of large diameter aortic necks and small aortic bifurcations in patients deemed unfit for open repair or declined for fenestrated endografts. Longer follow-up is required to assess the long-term safety with special focus on aortic neck dilation.
