Technical Tips about the Device Insertion in Thoracic Endovascular Aortic Repair (TEVAR)

Abstract

The first clinical endovascular aortic repair (EVAR) of a traumatic chest descending aorta was reported by Volodos in 1988. Although thoracic endovascular aortic repair (TEVAR) looks comparatively simple as an interventional procedure, according to the spatial relationship of aneurysm and aortic arch branches, aortic tortuosity and quality of aortic-wall plaque, it is difficult to carry out with low invasiveness without complications. Knowledge of many different approach techniques and various experiences are required to perform the procedure safely.
We present some difficult TEVAR cases from the viewpoint of device insertion, and explain some technical tips.
