血管重构的超声诊断技术进展

New advances in ultrasound diagnostic techniques for evaluation of vascular remodeling

血管重构是指血管为适应内外环境的改变而发生功能、形态和结构的一系列适应性变化。超声新诊断技术可发现在未出现形态学变化前的血管弹性功能的变化,亦能识别斑块内的新生血管。本文即综述血管重构的形成机制和临床意义,以及血管回声跟踪技术、瞬时波强技术、速度向量成像技术、血管内超声、实时三维超声技术和超声造影等血管重构的超声诊断技术进展,为评估血管功能和结构、诊断和治疗心血管疾病提供依据。

Vascular remodeling refers to a series of adaptive changes in the function, shape and structure of blood vessels in orderto adapt to the changes in the internal and external environment. New ultrasonic diagnostic techniques can find not only the changesof vascular elasticity function before the morphological changes, but also can identify the new blood vessels in the plaque. This paperreviews the for^nation mechanism of vascular reconstruction and its clinical significance, and new progress in vascular echo trackingtechnology, instantaneous wave intensity technique, speed vector imaging technology, intravascular ultrasound, real - time three -dimensional echocardiography and contrast-enhanced ultrasound, in order to provide a strong basis for the assessment of vascular functionand structure, as well as diagnosis and treatment of cardiovascular diseases.
