Survivors at first intervention after acute type A aortic dissection often necessitate additional interventions to avoid dilation and rupture of the remaining thoraco-abdominal aorta. During the first-stage arch procedure, the attempt to treat the descending thoracic aorta with a stent graft could attenuate this phenomenon and reduce the need for further open or endovascular reinterventions. In this short review article, the frozen elephant trunk technique was tested as influencing factor of aortic remodeling during follow-up analysis. Late results from the identified studies suggested promising rates of false lumen thrombosis of the descending thoracic aorta (78-100%), suggesting that aortic remodeling is highly probable with this approach. However, a longer surveillance of the aortic diameters is still necessary to confirm this initial hypothesis.
急性A型主动脉夹层初次干预后的幸存者通常需要额外的干预措施，以避免剩余胸腹主动脉的扩张和破裂。在一期主动脉弓手术中，尝试用支架移植物治疗降主动脉可能会减轻这种现象，并减少进一步进行开放或血管腔内再次干预的必要性。在这篇简短的综述文章中，在随访分析中，将“冰冻象鼻”技术作为主动脉重塑的影响因素进行了测试。已确定研究的晚期结果表明，降主动脉假腔血栓形成率很有前景（78%-100%），这表明采用这种方法很有可能实现主动脉重塑。然而，仍需要对主动脉直径进行更长时间的监测，以证实这一初步假设。
