Microvascular lymph node transfer shows promise for lymphedema treatment, improving lymphatic drainage and reducing limb swelling. This technique may also decrease infection risk and relieve neuropathic pain in patients.
Area of Science:
- Plastic Surgery
- Regenerative Medicine
- Lymphedema Treatment
Background:
- Microvascular lymph node transfer is a potential treatment for lymphedema.
- Lymphatic growth factor (VEGF-C) secreted by transferred nodes may promote lymphatic growth.
Purpose of the Study:
- To evaluate the clinical efficacy of microvascular lymph node transfer in lymphedema patients.
- To investigate VEGF-C secretion following lymph node transfer.
Main Methods:
- Analysis of 19 patients undergoing lymph node transfer (2007-2012).
- Assessment of lymphatic function via lymphoscintigraphy (transport index) and limb circumference.
- Measurement of VEGF-C in axillary seroma fluid.
Main Results:
- Improved transport index in 7/19 patients.
- Reduced limb circumference in 12/19 patients.
- Decreased infection episodes in patients with prior erysipelas (6/7).
- Pain relief in all patients with neuropathic pain (5/5).
- VEGF-C detected in seroma fluid post-transfer.
Conclusions:
- Lymph node flap reconstruction offers unique possibilities for lymphatic restoration.
- Further studies are needed to confirm the clinical efficacy of this technique.
- VEGF-C production may be influenced by factors beyond transferred lymph nodes.

Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
Functions of the Lymphatic and Immune System
The primary lymphoid organs, including the bone marrow and the thymus, serve as the maturation sites for lymphocytes. Secondary lymphoid organs, like the mucosa-associated lymphoid tissue, activate these lymphocytes and serve as...
Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
