Outcomes of endovascular aortic arch repair with an off-the-shelf modular inner branched stent-graft: an IDEAL 2a prospective multicentre trial

Wei Guo, Dan Rong, Hongkun Zhang, Leiyang Zhang et autres

BACKGROUND: Aortic arch pathologies are complex to treat. Alternatives include open surgery, hybrid surgery (endovascular aortic stent-grafting and open surgical debranching procedures) and total endovascular solutions with branched stent-grafts. Branched stent-grafts are the mainstream approach for endovascular repair, but they are primarily …
