Aortic dissection (AD) is characterized by abrupt onset, high mortality and poor prognosis. With the development of endovascular techniques for the management of aortic diseases in recent years, the therapeutic effect of AD has been greatly improved, and the treatment concept has also significantly changed. In respect of classification, many new classification systems have been proposed to guide the management of AD and, as for treatment of AD, although open surgery is still the main treatment approach for Stanford A dissection, endovascular repair has become the preferred procedure for complicated Stanford B dissection, and meanwhile, accumulating evidences indicate that favorable results may be achieved in non-complicated Stanford B dissection by early endovascular intervention.
