Transcatheter treatments for coarctation of the aorta include balloon angioplasty and stent implantation. However, balloon angioplasty has its limitations and may be associated with complications, such as, recoarctation, dissection, and aneurysm formation, in adult patients. Bare metal stent implantation has offered an alternative during the last decade or so, but covered stents have been used with increasing frequency more recently, to the extent that covered stent implantation is the preferred treatment in correctly selected patients. Primary stent insertion, whether bare metal or covered, prevents elastic recoil of the aorta and may provide better and more predictable results than balloon angioplasty. Furthermore, stents are preferable for the treatment of complex aortic arch obstructions, but their usage is limited to older patients, because of limitations associated with growth.
经导管主动脉缩窄治疗包括球囊血管成形术和支架植入术。然而，球囊血管成形术有其局限性，可能与成人患者的并发症有关，如再狭窄、夹层和动脉瘤形成。在过去十年左右的时间里，裸金属支架植入术提供了一种替代方法，但最近越来越频繁地使用覆膜支架，以至于在正确选择的患者中，覆膜支架植入术是首选治疗方法。无论是裸金属支架还是覆膜支架，初次支架置入都可以防止主动脉弹性回缩，并且可能比球囊血管成形术提供更好、更可预测的结果。此外，支架更适合治疗复杂的主动脉弓阻塞，但由于与生长相关的限制，其使用仅限于老年患者。
