A Conversion Case of Aortic Arch Aneurysm after TEVAR Utilizing a Collared Branched Graft

Abstract

An 83-year-old female patient was referred to our hospital because of an aortic arch aneurysm. At the age of 78, she had undergone zone 1 TEVAR with bypass surgery from the right axillary artery to the left common carotid artery and left axillary artery in another hospital. After that, the proximal landing zone expanded, and the type 1 endoleak led to aneurysmal expansion. Therefore, open surgical repair was planned. In the operative findings, the proximal stent graft diameter was 40 mm, and the diameter of the aorta was 45 mm. We chose a Vascutek Siena^TM Collared Branched Graft 26 mm (Terumo, Japan) and anastomosed the trimmed collar to the proximal stent graft covered with the aortic wall. We successfully reconstructed the aortic arch.
