Zone 2 Hybrid Thoracic Endovascular Aortic Repair: Is It a Good Option for All Types of Thoracic Aortic Disease?

Abstract: Background Zone 2 thoracic endovascular aortic repair (TEVAR) is performed for the treatment of various thoracic aortic diseases involving the left subclavian artery. This study aimed to analyze the late clinical outcomes of zone 2 hybrid TEVAR according to the various indications. Methods A total of 48 patients who underwent zone 2 TEVAR at our institution between December, 2010 and July, 2020 were enrolled. The indications were aortic aneurysm (AA, n = 15), acute type B aortic dissection (AD, n = 14), pene… Show more

“…11 Despite high technical success, this hybrid procedure has been erative CTA to 20% during mid-term follow-up. 12,13 It is still unclear how much circumferential endograft apposition is obtained in zone 2 after TEVAR with revascularization of the LSA. The aim of this study was to analyze the shortest apposition length (SAL) in the proximal sealing post-TEVAR CTA scan and to determine the amount of additional apposition length gained by LSA debranching.…”
