In Brief A new method for easy detection of functional lymphatic vessels in the superficial layer is reported. In a clinical trial, lymphography using indocyanine green dye for near-infrared fluorescence labeling in lymphaticovenular anastomoses was performed in 5 patients with lymphedema. The technique is simple and enables a minimally invasive operation to be performed. The results indicate that this technique is useful for acceptance as one of the examinations to evaluation of lymphedema. Intraoperative lymphography with indocyanine green dye for near-infrared fluorescence was performed on 5 patients. The study identified suitable locations for microvascular lymphaticovenular anastomoses.
Ogata et al. (2007) studied this question.
