Figure 1. Multi-point indocyanine green (ICG) lymphography (originally reported as multi-lymphosome lymphography). (A) Schematic illustration of multi-point ICG lymphography. The crosses indicate the injection points of ICG (the first web space, the proximal point of the lateral malleolus, and the lateral midline point at the level of the superior border of the patella). The red line indicates the lymphatic vessel in the Saphenous lymphatic area, the green line indicates the lymphatic vessel in the Lateral calf lymphatic area, and the blue line indicates the lymphatic vessel in the Lateral thigh lymphatic area. When performing lymphatic ultrasound, we apply the probe so that the lymphatic vessel and the probe are at right angles, imagining the running of these lymphatic vessels (-●); (B) Clinical pictures of multi-point ICG lymphography.
