Figure 1. ICG lymphography-mapped lymphatics are shown in the lower extremity after sequential rows of injections (circles) were given on the anterior and medial surfaces. The injection row levels have been numbered from distal to proximal. The pattern in black originated from row 1 (webspace level), and the pattern in red originated from row 2 (ankle level). Part of the ICG injected at row 2 entered the same channel highlighted by the row 1 injection and lengthened it further proximally. The pattern arising from row 3 (distal calf) injection is marked with blue lines and is seen overlapping partially with the level 1 and level 2 patterns. The highest level of injection points at 4 (proximal leg) did not show any further linear patterns, and since this was close to the popliteal fossa, no further injections were necessary.
