Novel Application of Branched Endograft for Preservation of Pelvic Circulation.

BACKGROUND: Endovascular repair of a proximal anastomotic pseudoaneurysm (APSA) of an end-to-side aortobifemoral bypass (ABF) can lead to pelvic ischemia. We present a novel application of branched aortic endograft to repair such pseudoaneurysm while preserving flow into the ABF and native aortoiliac system.

METHODS: A 71-year-old male with history of aortoiliac occlusive disease resulting in lifestyle limiting claudication was treated with an aortobifemoral bypass in 1999. The patient developed an 8.8 cm pseudoaneurysm at the aortic anastomosis. CTA demonstrated patent right common and internal iliac arteries with an occluded right external iliac artery and occluded left common and external iliac arteries.

RESULTS: A 24 × 80 mm endograft with an 8 × 15 mm posterior branch based on the Cook Zenith device (Bloomington, IN) was delivered via a right femoral artery exposure. The preloaded wire of the main body was snared via left brachial access. A 10F sheath was advanced into the side branch of the graft to deliver a 10 × 10-mm Bard Fluency (Covington, Georgia) stent graft into the right common iliac artery. The branch was reinforced proximally with an 8 × 17 mm Boston Scientific Express (Marlborough, MA) stent. The patient was discharged after 5 days. At 1 month, CTA demonstrated patent ABF, patent branch graft into the pelvis, and exclusion of the pseudoaneurysm.

CONCLUSIONS: Branch grafts can provide minimally invasive revision of a failing ABF, in this case an APSA, while preserving pelvic circulation and lower extremity perfusion.
