Abstract: Objective To investigate the clinical features of different types of aortic dissection, and to improve the ability for the diagnosis and treatment of aortic dissection. Methods The data of 68 patients with aortic dissection were analyzed, including baseline data, risk factors, clinical symptoms, treatment, and prognosis. Results Among the 68 patients with aortic dissection, 42 (61.76%) had Stanford A type aortic dissection and 26 (38.24%) had Stanford B type aortic dissection. Related risk factors were hypertension in 59 patients (86.76%), smoking in 26 patients (38.24%), and hyperlipidemia in 23 patients (33.82%), and there were no significant differences in risk factors between Stanford A type aortic dissection and Stanford B type aortic dissection. Of all patients, 61 (89.71%) had an initial symptom of chest/back/abdominal pain, and 7 (10.29%) had no obvious pain, and the patients with aortic dissection could also have the symptoms of lesions in the organs involved, such as acute myocardial infarction and intestinal obstruction. The initial symptom was chest pain for Stanford A type aortic dissection and abdominal pain for Stanford B type aortic dissection, with a significant difference between the two types. Conclusion Aortic dissection tends to have a high mortality rate and diverse clinical manifestations, and therefore, clinicians for initial diagnosis need to make an early diagnosis and perform early treatment, so as to improve the prognosis of patients.
