Elephant trunk and frozen elephant trunk are established procedures for the treatment of aortic arch pathologies, such as aneurysm or dissection. The aim of open surgery is to re-expand the true lumen, favouring correct organ perfusion and the thrombosis of the false lumen. Frozen elephant trunk, with its stented endovascular portion, is sometimes associated with a life-threatening complication: the stent graft-induced new entry. In the literature, many studies reported the incidence of such issue after thoracic endovascular prosthesis or frozen elephant trunk, but in our knowledge, there are no case studies about the occurrence of stent graft-induced new entry with the use of soft grafts. For this reason, we decided to report our experience, highlighting how the use of a Dacron graft can cause distal intimal tears. We decided to coin the term soft-graft-induced new entry to indicate the development of an intimal tear induced by the soft prosthesis in the arch and proximal descending aorta.
象鼻术和冰冻象鼻术是治疗主动脉弓病变（如动脉瘤或夹层）的既定手术方法。开放手术的目的是使真腔重新扩张，以利于器官的正确灌注和假腔血栓形成。带有支架血管内部分的冰冻象鼻术有时会伴有危及生命的并发症：支架移植物导致的新破口。在文献中，许多研究报道了胸段血管内假体或冰冻象鼻术后此类问题的发生率，但据我们所知，尚无关于使用柔软移植物导致支架移植物新破口发生情况的病例研究。因此，我们决定报告我们的经验，强调使用涤纶移植物如何导致远端内膜撕裂。我们决定创造“柔软移植物导致的新破口”这一术语，以表明柔软假体在主动脉弓和近端降主动脉中引起的内膜撕裂的发生。
