Abstract 19994: Outcomes Following Thoracic Endovascular Aortic Repair in Patients With Bovine Aortic Arch Anatomical Variants: A 14-year Single Centre Experience (original) (raw)

Circulation, 2014

Abstract

Introduction: Bovine aortic arch (BA) anatomical variants have been associated with an increased incidence of thoracic aortic disease but whether this anatomical variant affects outcomes after intervention remains unknown. We compare thoracic endovascular aortic repair (TEVAR) in patients with BA and those with a normal aortic arch configuration (NA). Methods: A prospectively maintained database of 250 patients who underwent elective and emergency TEVAR between 2000 and 2014 was analysed retrospectively. Computerised tomography angiograms were reconstructed using a TeraRecon Aquarius workstation to assess aortic morphology. Data analysed included in-patient mortality, stroke, papraplegia, incidence of endoleak, coverage/revascularization of the left subclavian artery (LSA) and the length of aorta covered. Results: Bovine aortic arch variants were identified in 48 patiens (19%), half of whom underwent TEVAR for thoracic aneursymal disease (TAA) and the remaining 24 for thoracic aorti...
