A rare case of lethal Najuta endograft collapse

BACKGROUND: The development of fenestrated endograft, Najuta endograft Kawasumi Laboratories, Inc, Tokyo, Japan) in thoracic endovascular aortic repair (TEVAR) has enabled the treatment of aortic arch aneurysms approaching zone 0 without the need of supra-aortic vessel branch reconstruction. However, the indications of Najuta remain controversial due to complications such as endograft collapse, which is rare and lethal. CASE PRESENTATION: We here report a 75-year-old male patient with arch saccular aneurysm. Because of his liver cirrhosis, 2 debranching TEVAR has chosen as a treatment using Najuta. After extrathoracic bypass was performed, a CTAG stent graft was implanted distal to the LSCA in order to deliver Najuta stent graft steadily. Najuta stent graft was successfully positioned in zone 0. However, he was suffered from stent-graft collapse. After additional TEVAR to salvage stent-graft collapse to zone 0, he complicated type A dissection, which was treated by ascending aorta replacement. After salvage operation complicated multiorgan failure and he died.
