Clinical outcomes of thoracic endovascular aneurysm repair using commercially available fenestrated stent graft (Najuta endograft)

摘要

Objective: Thoracic endovascular aneurysm repair (TEVAR) for the aortic arch aneurysm is challenging because of its curved anatomic configuration and the presence of the supra-aortic branches. The Najuta fenestrated endograft (Kawasumi Laboratories, Inc, Tokyo, Japan) was developed to treat aortic arch diseases, offering maximal proximal landing length while preserving the blood flow to the supra-aortic branches. We evaluated the perioperative and midterm outcomes of this fenestrated endograft.
