Conclusion
Stanford type A acute AD is a emergent and severe event in clinic.
The literature reported a pre-hospital mortality rate of 49% and a mortality rate of 47-57% within 30 days after admission[9,
10].
Although the optimal treatment remains controversial,
Song et al[11] suggest timely surgery by cutoff values of 16 mm for IMH thickness and 55 mm for external diameter of ascending aorta.
Multiple studies have shown that the aortic diameter is an independent predictor of dissection and intramural hematoma.
In this study,
the in-hospital mortality rate of conservative treatment after admission was as high as 62.01%,
and the mortality rate of emergency surgery was 12.59%.
Defining the lesion as early as possible and timely surgical treatment may have important implications for its prognosis.
We hypothesized that type A aortic dissection or intramural hematoma involving the pulmonary artery may also be a meaningful risk predictor of death.
