Patients
Three hundred twenty-five patients with ATAAD at Union Hospital from
February 2012 through February 2017 were studied. All patients were
diagnosed by surgery or imaging examinations, such as computed
tomography angiography (CTA), magnetic resonance imaging (MRI) or
echocardiography. Patients with chronic type A aortic dissection (n=4)
who were treated with intracavitary interventional therapy (n=6) or who
died after conservative treatment (n=2) were excluded. Finally, a total
of 313 patients (of whom 264 were male and 49 female; mean age, 48
years; range 22 to 70 years) were analyzed.
