Outcomes of intact thoracic endovascular aortic repair in octogenarians

Thoracic endovascular aortic repair (TEVAR) is a suitable alternative to open aortic surgery especially for older patients with poor general health and functional status. However, data on the benefit of TEVAR in elderly patients are limited. The aim of this study was to use a large national database to compare the outcomes of TEVAR in octogenarians vs nonoctogenarians in the treatment of thoracic aortic aneurysms and dissection. All patients who underwent TEVAR for nonruptured thoracic aneurysms or dissection (zones 1-5) between January 2014 and February 2019 were identified in the Vascular Quality Initiative database. The primary outcome was in-hospital mortality. Secondary outcomes included cardiac adverse events; neurologic events; respiratory complications; new-onset dialysis; leg compartment syndrome; postoperative hematoma in addition to spinal, bowel, arm, and leg emboli/ischemia; and return to the operating room. Outcomes were compared between octogenarians (age ≥80 years) and nonoctogenarians (age
