Abstract
In 1987 Nikolay Volodos performed the world's first endovascular treatment of aortic aneurysms. Endovascular technology has progressed significantly since then. There are now many thoracic endovascular aortic repair (TEVAR) systems commercially available. By applying them, we can treat many pathologies: aneurysms, dissections, aortic ruptures, and penetrating aortic ulcers. However, TEVAR technology still has its limitations, namely the risk of a retrograde type A dissection, the issue of precise landing in the distal landing zone, and the risk of air embolism and paraplegia. Furthermore, there are no appropriate stent grafts widely available to treat acute dissections. Those currently used are designed for aneurysms, not for dissections. As a result, there are several challenges facing the future TEVAR surgical community, such as the need to develop new and more precise systems with retrograde deployment for the distal landing zone, as well as to introduce flexible stent grafts to treat dissections. The endo-Bentall is being developed as an alternative treatment method for acute type-A aortic dissection.
