Abstract

The true incidence of aortic events (AEs) and reoperations (REDO) following elective total aortic arch replacement remains unknown. The aim of this study was to review the incidence of AEs and surgical REDO, and its respective outcomes after 1232 elective arch repairs at 11 European aortic centres. Retrospective chart review (in the absence of prospective data collection) was performed for statistical analysis. Follow-up was conducted during routine clinical examination or in a telephone interview with patients and/or their respective physicians. One hundred fifty-five (12.6%) patients were identified (median follow-up time 48.7 months). The recorded AEs comprised aortic dilatation (62.6%), rupture (15.5%), endoleak (11%), false aneurysm (3.9%), dissection (3.2%), infection (2.6%) and others (1.3%). REDO (open/endovascular) were performed in 85.8% of patients (n = 133). Intraoperative and in-hospital mortality in the REDO patients were 7.5% and 17.3%, respectively. Postoperative neurological complications comprised paraplegia (6.0%) and stroke (1.5%). Survival rates after REDO at 1, 3 and 5 years were 81.2%, 79.0% and 76.7%, respectively. Univariate analysis identified 'rupture' and 'diameter progression', 'older age at REDO' and the REDO strategies 'frozen elephant trunk' and 'no elephant trunk' as predictors of increased in-hospital mortality. Multivariate analysis identified 'older age at REDO' (P = 0.008) as the only independent risk factor for in-hospital mortality. AEs after elective arch surgery are not irrelevant and mostly involve the distal aspects of the adjoining aorta. In accordance with the underlying pathology, open or endovascular REDO may be performed with an acceptable outcome. Preparation of an adequate proximal landing zone at the time of primary arch surgery is advisable.
