Novel Endovascular Approach Using the Gore Iliac Branch Endograft for Short Iliac Anatomy

Abstract

Purpose: To report the use of a branched iliac endograft to maintain internal iliac artery (IIA) patency in a patient with an infrarenal aortic aneurysm and short common iliac arteries (CIA). Case Report: A 74-year-old man presented with an asymptomatic, fusiform, 67-mm infrarenal aortic aneurysm confirmed on computed tomography. The right CIA was funnel shaped and only 15 mm in length, providing no appropriate stent-graft landing zone. The left CIA measured 14 mm in diameter and 25 mm in length. Endovascular repair of the aneurysm with preservation of the IIAs was achieved using a Gore Iliac Branch Endoprosthesis for the short right CIA and a conventional limb to land in the left CIA. Follow-up scans to 24 months have shown continued patency of the IIA and no evidence of endoleak. Conclusion: The Gore Iliac Branch Endograft can be used to successfully treat patients with short CIA anatomy while preserving flow to the ipsilateral IIA, with maintained early patency of the IIA limb.
