Case Series of Aortic Arch Aneurysm in Patients with Bovine Arch Treated with Proximal Scalloped and Fenestrated Stent Graft

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.
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.
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.
