吲哚菁绿荧光成像技术在胸外科的应用

Application of indocyanine green fluorescence imaging technology in thoracic surgery

吲哚菁绿荧光成像技术是利用近红外光线激发吲哚菁绿的荧光属性,所发出的荧光信号再由专门的腔镜系统进行收集,并将信号传输到显示器上,从而实现术中实时成像的一门技术。它可以观察术中特定组织的靶向标记或评估组织血流灌注情况。近年随着对吲哚菁绿的物理特性研究越来越深入,吲哚菁绿荧光成像技术已经在血管探查、实质脏器灌注显影、软组织灌注评估、淋巴显影等方面得到应用。笔者围绕吲哚菁绿荧光成像技术在胸外科的应用进行阐述。

Indocyanine green fluorescence imaging technology is a real-time imaging technology.It takes advantage of the fluorescent properties of indocyanine green,which can be excited by near-infrared light.The fluorescent signal it emits is collected by a special endoscopic system,and the signal is transmitted to the display so that the image can be seen in real time.It can look at specific targets during the operation,or show the blood perfusion of the tissue.In recent years,the physical properties of indocyanine green have been studied more and more deeply.Clinically,indocyanine green fluorescence imaging technology has been used in many aspects,such as vascular exploration,parenchymal organ perfusion development,soft tissue perfusion evaluation,lymphatic development,etc.This review focuses on the indocyanine green fluorescence imaging technology in thoracic surgery.
