Changes in the diagnosis and management of acute aortic syndrome and associated mortality in the last 20 years.

Mortality is high in acute aortic syndrome (AAS), which therefore requires early treatment. This study aimed to analyze changes in the diagnosis and treatment of AAS over 20 years at our center. From 1999 to 2018, 451 patients diagnosed with AAS (336 men; mean age, 60.9±12.4 years) were prospectively included (270 type A and 181 type B). Clinical variables, diagnosis, treatment, and in-hospital complications were analyzed. The use of computed tomography (CT) as the first-line diagnostic technique increased from 62.8% to 94.2% (P <.001). Surgical treatment of type A AAS rose from 67.4% to 82.5% (P=.09). Mortality from type A AAS decreased significantly from 53.1% to 26.3% (P <.001) as a result of the fall in mortality from surgical treatment (from 45.4% to 17.0%; P <.001). The use of medical treatment alone for type B AAS decreased from 91.8% to 61.7% (P <.001) due to the greater use of endovascular treatment. Mortality from type B AAS showed no significant reduction (16.2% to 10.6%; P=.15). The diagnosis and treatment of AAS has changed substantially in the last 2 decades. CT has become the first-line diagnostic technique for AAS. In type A AAS, mortality has fallen significantly due to improvements in the results of surgical treatment. In type B AAS, the use of medical treatment alone has decreased due to the expansion of endovascular treatment, although in-hospital mortality has not decreased significantly.
