The aim of this study is to further explore the optimal screening factors for functional lymphatic vessels in lymphaticovenous anastomosis in patients with lymphedema.
By analyzing the size of lymphatic vessels (0.3-0.6mm), ICG imaging, contraction characteristics of lymphatic vessels and lymphatic flow in patients with lymphedema, the effect of functional lymphatic vessel selection on lymphatic drainage in patients with lymphedema was judged during operation, so as to provide a more scientific basis for the selection of functional lymphatic vessels in clinical surgery.

| lymphaticovenous anastomosis | Procedure | lymphaticovenous anastomosis |
| Measure | Description | Time Frame |
|---|---|---|
| Rate of size(0.3-0.6mm) | size of lymphatic vessels | through study completion, an average of 2.5 year |
| Rate of lymphatic vessels contractility | When observing lymphatic vessels in fluorescence mode, a contraction occurring within 10 seconds is considered as contractility positive | through study completion, an average of 2.5 year |
| Rate of flow | while the presence of lymphatic fluid flowing out after cutting the lymphatic vessel is considered as flow positive | through study completion, an average of 2.5 year |
| Rate of ICG | When observing lymphatic vessels in fluorescence mode, lymphatic vessel fluorescence is considered as ICG positive | through study completion, an average of 2.5 year |
