We performed ICG lymphography.8,9 To explain shortly, we injected 0.1 mL of ICG (0.5% Diagnogreen; Daiichi Pharmaceutical, Tokyo, Japan) subcutaneously into the second interdigital space of the right hand and the palmer side of the wrist and observed with an infrared camera system (Photodynamic Eye; Hamamatsu Photonics, Hamamatsu, Japan). We observed dermal backflow, which indicated the lymphatic stasis in the whole right upper limb and diagnosed our patient with lymphedema.10 Lymphoscintigraphy showed dermal backflow in the same area as ICG lymphotraphy. She started wearing elastic sleeve (20 mm Hg), and improvement in lymphedema symptoms was observed. As there was still stiffness in the right upper limb, which meant that there was still lymphatic stasis, we decided to perform LVA 5 months after the first consultation.
