Finding the Best Way to Map Lymphatic Vessels Before Surgery

Thu Nov 06 2025

Introduction

Lymphaticovenous anastomosis (LVA) surgery requires precise planning, particularly in locating lymphatic vessels. This study compares two pre-surgical methods: high-frequency ultrasound (HFUS) and indocyanine green (ICG) fluorescent lymphography.

Methods

High-Frequency Ultrasound (HFUS)

  • Technology: Uses sound waves to create body images.
  • Advantages:
  • Non-invasive.
  • No injections required.
  • Real-time imaging.
  • Disadvantages:
  • May lack precision in certain cases.

Indocyanine Green (ICG) Fluorescent Lymphography

  • Technology: Uses a special dye that glows under specific lights.
  • Advantages:
  • Provides detailed images.
  • Disadvantages:
  • Requires injection.
  • May not perform well in damaged lymphatic systems.

Study Findings

  • Both methods have unique advantages and limitations.
  • HFUS may be better suited for severe lymphedema cases.
  • ICG may offer more detailed imaging in less severe cases.

Study Limitations

  • Retrospective study: Analyzed past data rather than new experiments.
  • Prospective studies may provide more reliable results.

Conclusion

  • The choice between HFUS and ICG depends on individual patient needs.
  • Factors to consider:
  • Severity of lymphedema.
  • Patient comfort.
  • Precision required for surgery.
  • Further research is needed to determine the optimal method for each situation.

questions

    If high-frequency ultrasound is so precise, why can't it find my missing socks?
    Can the findings from this retrospective study be generalized to other types of lymphedema or different patient populations?
    What are the long-term outcomes and complications associated with each method, and were these adequately addressed in the study?
