Area of Science:

  • Microsurgery
  • Surgical Oncology
  • Lymphedema Management

Background:

  • Chronic lymphedema, often resulting from breast cancer treatment or lower extremity issues, requires effective management strategies.
  • Vascularized lymph node transplant (VLNT) offers a safe and effective treatment for lymphedema, with benefits becoming fully apparent two years post-surgery.
  • A key challenge in VLNT is ensuring adequate lymph node inclusion in the flap, necessitating reliable pre-harvest identification methods.

Purpose of the Study:

  • To evaluate the use of radiotracer (Technetium-99m sulfur colloid) and indocyanine green (ICG) for improved lymph node identification during Vascularized Lymph Node Transplant (VLNT).
  • To enhance the reliability and success rate of VLNT procedures by ensuring accurate lymph node harvesting and transfer.

Main Methods:

  • Utilizing Technetium-99m sulfur colloid, similar to sentinel lymph node biopsy techniques, to identify lymph nodes prior to surgical harvest.
  • Employing methylene blue dye and indocyanine green (ICG) in conjunction with radiotracer to confirm lymph node presence before and after microvascular transfer.
  • Conducting a pilot study involving eight cases to assess the efficacy of the combined identification methods.

Main Results:

  • The pilot study successfully identified lymph nodes in all eight transferred tissue samples.
  • The use of radiotracer and ICG demonstrated high reliability in localizing lymph nodes for harvest and transfer.
  • This method provides confirmation of lymph node presence throughout the VLNT procedure, from identification to post-transfer.

Conclusions:

  • Radiotracer and ICG are effective adjuncts for identifying lymph nodes in VLNT, improving procedural reliability.
  • The enhanced identification method ensures adequate lymph node quantity and vascularity, crucial for successful lymphedema treatment.
  • This technique offers a more dependable approach to VLNT, potentially improving outcomes for patients with chronic lymphedema.
