Patients were classified as ascending or descending groups according to the segment where the maximal aortic diameter was measured. Primary end points were expansion rates and factors associated with TAA growth.<h4>Results</h4>We investigated 137 patients, 70 (51.1%) of whom were women; 78 (56.9%) were in the ascending and 59 (43.1%) were in the descending group. Median baseline maximal aortic diameter was 48.5 mm (interquartile range, 47.0-49.9 mm) for asceThe Journal of thoracic and cardiovascular surgeryDifferential expansion and outcomes of ascending and descending degenerative thoracic aortic aneurysms.PMC9547986R33 AG058738R21 AG058738Greason KLPochettino AHuang YBagameri GSchaff HVDeMartino RRTodd AfalseDifferential expansion and outcomes of ascending and descending degenerative thoracic aortic aneurysms.<h4>Objective</h4>To evaluate expansion of degenerative thoracic aortic aneurysms (TAAs) and compare results between ascending and descending TAAs.<h4>Methods</h4>Among patients with diagnosis of degenerative TAA (1995-2015) in Olmsted County, we studied those having at least 2 computed tomography scans of TAA throughout the follow-up.
