Abstract: Abstract: Aortic dissection is a serious disease, and it has a high mortality and disability rates. In recent years, with the application of a variety of imaging tests, especially the development of CT imaging technology, the diagnostic rate of aortic dissection is increased significantly. The recognition and prognostic evaluation of aortic dissection also deepened with the improvement of biochemical detection. A variety of operative modes can be selected according to involved scope of aortic dissection. Especially to the therapeutic method of aortic arch department, not only traditional elephant trunk technique but also Sun’ s operation and triple-branched stent grafting can be selected. Mortality and complication rates have been dropped significantly after using new operative modes. The application of thoracic endovascular aortic repair (TEVAR) turns the invasive therapy to minimally invasive therapy for the treatment of aortic dissection. But TEVAR has strict imaging constraints. However TEVAR’ s indications are extended by debranching operation, which makes the patients with surgical contraindications to conform to the operation indication. In this article, on the basis of development of diagnosis and treatment of aortic dissection in recent years, the current early diagnosis, laboratory examination, prognostic evaluation, and the present treatment methods are summarized for reference in basic and clinical research.
