ICG lymphangiography

Abstract

Fluorescent lymphangiography using indocyanine green (ICG lymphangiography) has high resolution and reproducibility, enabling evaluation of lymph fluid reflux in skin in detail and identification of lymphatic position effectively. Also, it can be safely performed even in pediatric patients, as it requires no radiation exposure, and allergic reactions risks are low. In fact, as lymphatic venous anastomosis has become a popular treatment for lymphedema, ICG lymphangiography has become widely used in clinical practice. Furthermore, the indications have expanded and been applied to lymphatic diseases other than lymphedema, and individual lymphatic flow is becoming unveiled. In this chapter, I will outline the practice of the method, which plays an important role in the diagnosis of various lymphatic diseases.
