Elbadawi A, Elgendy IY, Jimenez E, et al. - In view of the paucity of data on the contemporary outcomes and trends of elective thoracic aortic aneurysm repair and aneurysm-associated acute aortic syndrome, researchers here identified hospitalizations for elective thoracic aortic aneurysm repair and aneurysm-associated acute aortic syndrome via query the NIS database years 2012-2016. A total of 24,295 hospitalizations were identified for elective thoracic aortic aneurysm repair and 8,875 hospitalizations for aneurysm-associated acute aortic syndrome suggesting that the number of hospitalizations for acute aortic syndrome is nearly one third that for elective thoracic aortic aneurysm repair. For elective aortic repair, acute rupture and acute dissection, in-hospital mortality was 2.4%, 39.4% and 6.2%, respectively. Relative to acute aortic syndromes, elective aortic repair was linked with lower incidences of major in-hospital complications and shorter length of stay.
