Primary outcomes included intraoperative mortality, 30-Day mortality, and postoperative stay. Secondary outcomes included postoperative complications. Outcomes were analyzed using Chi-squared, Fisher\u2019s Exact, and t-tests, with significance set at p\u2009&lt;\u20090.05.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>A total of 107 patients were included, 27 of whom (25%) had Intramural Hematoma and 80 (75%) had Type A Aortic Dissection. There were no differences in preoperative characteristics such as age, gender, and comorbidities, and no differences in perioperative characteristics such as case length, cardiopulmonary bypass, aortic cross-clamp, and circulatory arrest times. When comparing postoperative outcomes, there was a higher rate of postoperative pericardial effusions requiring pericardial window in the Intramural Hematoma cohort compared to the Aortic Dissection cohort (15% [n\u2009=\u20094] vs. 3% [n\u2009=\u20092]; p\u2009=\u20090.02). There were no differences in other primary outcomes such as intraoperative mortality, 30-Day mortality, and postoperative length of stay. There were also no differences in the rates of postoperative complications such as bleeding requiring reoperation, cerebrovascular accident, atrial fibrillation, pleural effusion requiring thoracentesis, and surgery-related Emergency Department visits.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Our analysis demonstrates similar outcomes for patients undergoing Ascending Aortic Arch repair between patients with Intramural Hematoma and Type A Aortic Dissection. Despite the higher rate of required postoperative pericardial windows in the Intramural Hematoma cohort, the overall primary outcomes remained comparable.
