Changes in stent-graft orientation after frozen elephant trunk treatment in aortic arch aneurysm.

ABSTRACT:

Background

Changes in stent graft (SG) orientation after frozen elephant trunk (FET) treatment for aortic arch aneurysms are not well understood. This study investigated changes in SG orientation and their effects on aortic events after FET for aortic arch aneurysms.

Methods

This study included 57 patients with true aneurysms who underwent elective total arch replacement using FET between 2016 and 2023. Postoperative SG angle, descending aortic (DA) diameter at the end of the SG, and the DA angle were measured retrospectively by using enhanced computed tomography (CT).

Results

Median patient age was 74 years. The median stent size was 33 mm, and the stent length was 12 cm (range, 23-37 mm and 6-15 cm). Enhanced CT showed that all the patients had completely thrombosed
