Abstract | PURPOSE: The bovine arch is the most common variant of the aortic arch and occurs when the innominate artery shares a common origin with the left common carotid artery. We report an endovascular repair of aortic arch aneurysm in patients with a bovine arch using the Najuta proximal scalloped and fenestrated stent graft. MATERIALS AND METHODS: Thoracic endovascular aneurysm repairs using the Najuta stent graft were performed at our facility. It was inserted and deployed at a zone 0 with precise positional adjustment of the scallop of the stent graft to the brachiocephalic trunk. RESULTS: Overall, eight patients with bovine aortic arch were treated with fenestrated endovascular aneurysm repair. Technical success was 100% with no 30-day death. The follow-up period ranged from 7 to 29 (median 12) months. None of the patients had a stroke or paraplegia, and no endoleak was observed. All brachiocephalic trunks scalloped, and the left subclavian artery fenestrated vessels remained patent during the follow-up period. CONCLUSION: The Najuta stent graft repair of aortic arch aneurysms in patients with a bovine arch is a safe and effective treatment option, with good immediate and short-term results.
