Early- and mid-term aortic remodelling after the frozen elephant trunk technique for retrograde type A acute aortic dissection using the new Japanese J Graft open stent graft.
We previously performed the frozen elephant trunk (FET) technique for acute type A aortic dissection to try to improve the long-term prognosis. In this study, we report the mid-term results of the FET technique for treating retrograde type A acute aortic dissection using a new device, the J Graft open stent graft (JOSG). ⋯ The use of the FET technique with the JOSG for retrograde type A acute aortic dissection provides good outcomes. With the proper use of the JOSG, it is possible to expand the true lumen and eliminate antegrade false-lumen flow, resulting in good aortic remodelling. Furthermore, there should be obliteration of the false lumen from the stent graft to the aortic valve, and this might reduce long-term complications.
