Technical Feasibility of Arch Branched Endograft Repair in Type A Aortic Dissection with Prior Ascending Aortic Replacement

Abstract

were prospectively included in the single center registry study. The primary outcome was death from any causes. Results-A total of 140 patients who were confirmed with Stanford type A aortic dissection involving aortic arch by CTA on admission were enrolled. The mean (AESD) age was 61.8AE7.3 years; 35.7% of the patients were women. Either ascending graft branch approach (18.6%) or femoral artery approach (81.4%) was applied for delivery of endovascular grafts into aortic arch. The incidence of death at 30 days and 1 year were 6.4% and 10.3%, respectively. The incidence of radiological diagnosis of stroke and endoleak at 30 days were 3.6% and 7.1%. In multivariate models, patient age (!60) was associated with reduced survival and antegrade deployment of endovascular graft through ascending graft branch was associated with increased risk of endoleak. Conclusion-The results of this registry study revealed the clinical experience of endovascular aortic
