Objective:To explore the selection of the treatment methods for acute aortic dissection.Methods:Thirteen patients with acute aortic dissection were studied and analyzed.Results:Of the 13 patients

2 received pharmacotherapy;6 underwent surgical treatment;2 were treated with inplantation of intravascular stent-grafts;1 experienced no treatment because of the ischemic necrosis of the abdominal organs

and 2 suddenly died of the rupture of aortic dissection in the course of emergent management.Conclusion:The emergent pharmacotherapy is essential to all patients with acute aortic dissection.The emergent surgical treatment of acute aortic dissection is selected mainly according to the Debakey Classification.Patients with Debakey Type Ⅰ and Ⅱaortic dissection should undergo operation as early as possible.The outcome of pharmacotherapy is similar to that of surgical treatment based on suitable indications for Debakey Type Ⅲ aortic dissection.Debakey Type Ⅲ aortic dissection can be treated by the intravascular stent-grafts too.
