Abstract: Aortic dissection is recognized as a dangerous disease.Although AD cannot be detected before it occurs，this does not mean that it cannot be prevented.Currently，it is believed that the control of blood pressure can prevent the occurrence of AD，while the stereotyped blood pressure control will affect the normal life of some people.Theoretically，the personalized blood pressure control plan can solve the above problems，but its formulation needs to be based on the elasticity of the aortic wall.This paper will discuss the feasibility of individualized depressurization.

Key words: aortic dissection, 〓elasticity, blood pressure control
