3D打印技术在主动脉夹层中的应用进展

Application Progress of 3D Printing Technology in Aortic Dissection

主动脉夹层(AD)是常见的急性主动脉综合征,临床上通常采用CT血管造影(CTA)检查评估AD。无论是开胸外科手术或腔内修复介入手术都需要手术医师对AD患者的主动脉及分支血管的解剖信息充分把握。但CTA影像只能通过电脑屏幕二维显示,需要医师在大脑中构建三维结构;其次,AD患者的主动脉弓上分支血管也存在明显的个体性差异,以上两点对于临床经验丰富的医师都是很大的挑战。随着医学与技术的发展,3D打印技术在临床医学中已得到广泛应用,近年来也逐渐应用于主动脉夹层这一疾病中。本综述主要阐述近年来3D打印技术在不同分型的主动脉夹层诊治中的应用进展,探讨3D打印技术在主动脉夹层疾病中的价值,为实现精确化、个体化疾病治疗提供参考。

Aortic dissection(AD)is a common acute aortic syndrome.Clinically,CT angiography(CTA)is usually used to evaluate AD.Whether it is open thoracic surgery or endovascular repair interventional surgery,surgeons need to fully grasp the anatomical information of the aorta and branch vessels of AD patients.However,CTA images can only be displayed on a computer screen in two dimensions,which requires doctors to construct three-dimensional structures in the brain;secondly,there are also obvious individual differences in the branches of the aortic arch in AD patients.The above two points are great challenges for doctors with rich clinical experience.With the development of medicine and technology,3D printing technology has been widely used in clinical medicine,and has been gradually applied to the disease of aortic dissection in recent years.This review mainly describes the application progress of 3D printing technology in the diagnosis and treatment of different types of aortic dissection in recent years,and discusses the value of 3D printing technology in aortic dissection,so as to provide reference for the realization of accurate and individualized disease treatment.
