保留主动脉瓣主动脉根部置换术的研究进展

Progress in Valve-sparing Aortic Root Replacement

多年以来,主动脉瓣和主动脉根部置换术被认为是主动脉根部瘤的标准治疗方法。随着人们对主动脉瓣置换术后并发症危害性认识的增加,和对主动脉瓣根部解剖及生理特点认识的深入,保留主动脉瓣主动脉根部置换技术有了较大发展。我们主要介绍主动脉瓣关闭不全的病因和分类、主动脉瓣保留技术及临床结果。

Replacement of the aortic valve and aortic root has been the standard surgical strategy for patients with aortic root aneurysm for many years.Along with the increasing knowledge about the aortic root anatomy and physiology,and complications after aortic valve replacement,the technique of valve-sparing aortic root replacement has developed greatly.We focus on the etiology and classification aortic valve insufficiency,the valve-sparing techniques and clinical outcomes of valve-sparing aortic root replacement in this review.
