Thoracic aortic aneurysm repair using the elephant trunk technique and associated complications.

The frozen elephant trunk stent has greatly facilitated the repair of elective and emergency arch and proximal descending thoracic aortic aneurysms and dissections. As one of the few tertiary hospitals that routinely inserts and images the floating and frozen elephant trunk grafts, we aim to provide an up-to-date illustration of the contrasting methods of elephant trunk thoracic aortic aneurysm repair through a computed tomography (CT) review and detail the common radiological interpretation pitfalls in addition to the most significant associated complications.
