Figure 1. The intraoperative photographs showed a lymphatic channel and a small venule (A) were anastomosed under a microscope
(B). The intraoperative ICG fluoroscopy revealed the patency of the anastomosis (C).

Figure 2. We present measurements of leg circumferences at admission (A), postoperative day (B) and 2 weeks at outpatient
clinic (C).
