This study evaluated trends in acute aortic syndrome operation incidence relative to proximal aortic surgical volume in the USA.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>A retrospective analysis of the National Inpatient Sample in 2005\u20132014 was performed. Acute aortic syndrome and TAA were identified with International Classification of Diseases, 9th edition diagnosis codes. Proximal aortic surgery was defined as the diagnosis of acute aortic syndrome or TAA with an aortic procedure and either cardioplegia, cardiopulmonary bypass or other cardiac operation. Annual rates of acute aortic syndrome surgery and proximal thoracic aneurysm surgery were adjusted for US population. Trends were evaluated using linear regression.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>We identified 38\u2009442 operations for acute aortic diagnoses and 74\u2009953 operations for TAAs. Case volume for acute aortic syndromes increased from 0.93 to 1.63 per 100\u2009000 (P\u2009=\u20090.001), and aneurysm surgery increased from 1.75 to 3.19 per 100\u2009000 (P\u2009&amp;lt;\u20090.001). Patient and hospital characteristics differed between acute aortic and aneurysm operations, with black patients being most notably underrepresented in the aneurysm population (4.9% vs 17.0%, P\u2009&amp;lt;\u20090.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>Acute aortic syndrome operative volume increased from 2005 to 2014 despite increasing rates of proximal aortic aneurysm surgery.
