[Endovascular Treatment Using the Fenestrated Stent Graft for Distal Aortic Arch Aneurysm with Aortic Arch Vessel Anomalies;Report of a Case].

We herein present a case of distal aortic arch aneurysm associated with the bovine arch and the isolated left vertebral artery (ILVA). Incorporating 2 fenestrations, we successfully performed an endovascular repair using the commercially available Najuta fenestrated stent graft system. During surgery, the Najuta was deployed in the aorta so as to allow for the proximal fenestration to be aligned with the orifice of the 1 branch of the aortic arch, and the distal fenestration with the orifice of the ILVA and that of left subclavian artery. Postoperatively, the patient's recovery went well without any cerebral complications, and in a subsequent computed tomography (CT), the patency of all aortic arch vessels and absence of endoleaks was confirmed. For cases of distal aortic arch aneurysm associated with arch anomalies, the endovascular treatment using the Najuta system is not only simple but also reliable in preserving blood flow to the brain and upper extremities.
