About this study

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.

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • lymphedema Paitent

Exclusion criteria

  • myoedema Paitent；lipedema Paitent

Treatment and study plan

Lymphaticovenous Anastomosis

Procedure

lymphaticovenous anastomosis

Primary outcomes

  1. Rate of size(0.3-0.6mm)

    Time frame: through study completion, an average of 2.5 year

    size of lymphatic vessels

  2. Rate of lymphatic vessels contractility

    Time frame: through study completion, an average of 2.5 year

    When observing lymphatic vessels in fluorescence mode, a contraction occurring within 10 seconds is considered as contractility positive

  3. Rate of flow

    Time frame: through study completion, an average of 2.5 year

    while the presence of lymphatic fluid flowing out after cutting the lymphatic vessel is considered as flow positive

  4. Rate of ICG

    Time frame: through study completion, an average of 2.5 year

    When observing lymphatic vessels in fluorescence mode, lymphatic vessel fluorescence is considered as ICG positive
