TEM Classification of Aortic Dissection-The Evolving Scoring System: A Literature Review

Abstract

Aortic dissection is an acute presentation that, if unnoticed, poses a significant risk to life. Anatomically, it is defined as a tear in the intimal layer of the aorta, but management differs significantly based on the location of this tear. Traditionally the Stanford and DeBakey classifications have been used to distinguish tear types and thus guide the most favourable management option, be it medical optimisation or surgery. Recently, a new Type-Entry-Malperfusion classification has been proposed to more accurately define and thus risk stratify patients with aortic dissection. This review summarises the Type-Entry-Malperfusion classification and highlights its potential advantages and limitations compared to other classifications. Clinical insights and potential barriers to adopting this classification are also described in this review.
