This review details lymphatic anatomy, physiology, and lymphedema pathophysiology. Understanding lymphatic system function and dysfunction is crucial for diagnosing and managing lymphedema.

Area of Science:

  • Lymphatic System Biology
  • Vascular Physiology
  • Pathophysiology

Background:

  • The skin lymphatic system comprises initial lymphatics, precollectors, collectors, and ducts, draining lymph to regional nodes.
  • Interstitial fluid enters lymphatics via openings and vesicular transport, with uptake enhanced by compression.
  • Lymphatic transport relies on lymphangion contractions generating suction for fluid absorption and expulsion.

Purpose of the Study:

  • To review current knowledge of lymphatic anatomy and physiology.
  • To discuss the pathophysiology of lymphedema.
  • To elucidate the mechanisms underlying fluid accumulation and tissue changes in lymphedema.

Main Methods:

  • Literature review of lymphatic anatomy and physiology.

Related Experiment Videos

  • Analysis of lymphedema pathophysiology mechanisms.
  • Synthesis of information on lymphatic system abnormalities and their consequences.

    • Main Results:

    • Lymphedema involves congenital or acquired abnormalities in lymphatic vessels and nodes.
    • These abnormalities can cause lymphatic hypertension, valvular insufficiency, and lymphostasis.
    • Fluid accumulation stimulates fibroblasts, leading to collagen/glycosaminoglycan deposition, skin hypertrophy, and elastic fiber destruction.

    Conclusions:

    • Lymphedema results from complex lymphatic system dysfunction.
    • Understanding these mechanisms is key for therapeutic strategies.
    • Further research into lymphatic regeneration and repair is warranted.
