概述

主动脉夹层(AD):内膜撕裂,血液被压入主动脉中层(产生假腔),占62%-88%。壁内血肿(IMH):滋养血管破裂,产生并不与主动脉腔相交通的血肿,占主动脉综合征的6%,临床上等同于AD。穿透性溃疡(PU):动脉粥样硬化斑块穿透弹力层,中膜出血,占10%-30%。AD分型和总体预后目前临床上常用的AD分类方法主要有DeBakey和Stanford两种分型方法。DeBakey分型将AD分为三种类型,其分型的依据是AD撕裂的位置和夹层沿主动脉扩展的情况:I型是指夹层的原发破口起源于升主动脉并向远

Aortic aneurysm is defined as having a permanent localized dilatation of the aorta, with at least 50% increase in diameter compared with the expected normal diameter of that aortic segment.The same guidelines do not offer a definition for a localized aortic dilatation of <50% of the expected normal diameter, commonly referred to in clinical practice as mild aortic dilatation. Further, this definition does not specify what represents a normal diameter. It has been recognized that aortic diameters are affected by age, sex, body size, and imaging modality.Thus, without taking these factors into account, normal diameters can be misclas- sified as abnormal.

主动脉瘤被定义为主动脉永久性局部扩张,与主动脉段的预期正常直径相比,直径增加至少50%。相同指南未提供局部主动脉扩张<50%的定义 预期正常直径,通常在临床实践中称为轻度主动脉扩张。 此外,该定义未指定代表正常直径的内容。 已经认识到主动脉直径受年龄,性别,体型和成像模式的影响。因此,如果不考虑这些因素,正常直径可能被错误地分类为异常。
