Summary
Microsurgical lymphatic grafting safely bridges blockades, significantly reducing limb swelling. This technique offers long-lasting relief for lymphedema patients, especially when initiated before severe tissue changes occur.
Area of Science:
- Microsurgery
- Vascular Surgery
- Lymphedema Treatment
Background:
- Localized lymphatic blockades, often resulting from lymphadenectomies, cause significant limb swelling (lymphedema).
- Conservative treatments may not fully resolve severe lymphatic system blockages.
Purpose of the Study:
- To evaluate the efficacy of autologous lymphatic grafts in bridging localized lymphatic blockades.
- To assess the long-term outcomes of microsurgical lymphatic reconstruction for lymphedema.
Main Methods:
- Harvesting autologous lymphatic grafts (up to 30 cm) from the thigh.
- Anastomosing lymphatic grafts to bridge localized lymphatic blockades in the arm, axilla, and lower extremities.
- Utilizing advanced microsurgical techniques for vessel connection.
Main Results:
- Significant reduction in limb volume for both arm and lower extremity lymphedema.
- Arm lymphedema volume decreased from 3368 cm³ to 2567 cm³ (p < 0.001) initially, with sustained reduction at long-term follow-up (2273 cm³ after 10 years).
- Lower extremity lymphedema volume reduced from 13098 cm³ to 10578 cm³ (p < 0.001), maintaining improvement over four years.
Conclusions:
- Autologous lymphatic grafting is a safe and effective microsurgical technique for treating localized lymphedema.
- The procedure demonstrates long-lasting, stable results in reducing limb volume.
- Early consideration of microsurgical reconstruction is recommended to prevent irreversible secondary tissue changes.
