Aortic dissection is a disease with high mortality rates. Due to the urgency of time, the diagnosis, treatment processes, and strategies of acute aortic dissection follow specific guidelines. However, patients with chronic aortic dissection are often neglected. Choosing the best medication therapy and surgical interventions remains challenging, and there is still a lack of guideline recommendations. With the improvement of imaging diagnostic methods for aortic diseases, the progress of endovascular surgical techniques, and the development of new endovascular graft devices in recent years, clinical data of the treatment of chronic aortic dissection is also gradually increasing. This article summarized the current new technologies and clinical research results for the diagnosis and treatment of chronic aortic dissection, aiming to provide new suggestions for the diagnosis and treatment of chronic aortic dissection.
