Operative Times and Outcomes of Complex Endovascular Repairs of Thoracoabdominal Aneurysms

Owing to the significant morbidity and mortality of open thoracoabdominal aortic aneurysm surgery, complex endovascular repairs (eTAAA) have become increasingly common, but still carry substantial risk. These repairs require large bore access, with resultant pelvic and lower extremity ischemia. We therefore hypothesized that operative timing would be associated with outcomes, as efficient surgery would limit the ischemic time as well as anesthesia time.
