Abstract
BACKGROUND: Thoracic aortic aneurysms (TAAs) contribute significant mortality if left untreated, but surgical repair has historically carried substantial risks. METHODS: We sought to observe trends and outcomes of open and endovascular thoracic endovascular aneurysm repair thoracic aortic repairs, so conducted a retrospective review of all patients who presented for management of TAAs from 2003 to 2013 at 2 hospitals in Sydney, Australia. RESULTS: A total of 179 patients presented with TAAs over the study period, including 5 ruptures. Fifty-two were treated nonoperatively, with 127 surgically repaired. Operative duration was significantly shorter in endovascular than open repair of arch (193 ± 108 vs. 396 ± 98 min, P = 0.0001) and descending aneurysms (242 ± 116 vs. 422.5 ± 161 min, P = 0.003). There were no differences in mortality or complication rates (including paraplegia), duration of hospital or intensive care unit stay, or transfusion requirements between endovascular and open TAA repairs. CONCLUSIONS: Apart from reduced surgical duration, this study revealed no benefits of endovascular over open TAA repair. Overall morbidity and mortality were low, even in elderly patients.
