The frozen elephant trunk (FET) technique is an increasingly common procedure to treat complex extensive aortic disease both in elective and emergency setting. In a contemporary era, several prostheses are available to be used by surgeons performing such procedures, merging the advantages of endovascular and conventional surgery and preparing a more useful landing zone for second-stage downstream endovascular or open repair. Thoraflex hybrid (Terumo Aortic, Scotland) is a largely used hybrid vascular device merging a conventional surgical vascular graft made of gelatin-sealed woven polyester graft with a nitinol self-expanding stent graft. Since its release in 2012, this prosthesis has gained a large consensus, mainly for the plexus version, which allows for single reimplantation of the epiaortic vessels. In the last few years, new devices have come out to offer new specific weapons to be used by the surgical team in different clinical scenarios. In this context, the need of making the supra-aortic vessel debranching easier and more functional to our surgical technique has pushed our demand for a customization of a conventional Thoraflex hybrid. Here we report a modification to its standard design, the concept beyond the "Custom device" and its potential advantages with regards to our peculiar implantation technique and intraoperative cerebral perfusion during circulatory arrest time.
