[Research progress of acute aortic syndrome].

Acute aortic syndrome(AAS) is a lethal disease with acute onset and a high mortality rate as well as a higher incidence rate especially in an aging population. The diagnostic techniques of AAS have been improving in recent years. Many serum biomarkers have been shown to have the potential of further clinical implication. Advancement of imaging techniques has also improved the accuracy of early diagnosis. Although traditional treatment modality involving open surgery is life-saving, it still has a high mortality rate and a high major morbidity rate. The increasing utilization of endovascular techniques has greatly improved the prognosis of AAS, while it still need further optimization to be applied in different subgroups of patients.
