Questions and Answers

What distinguishes lymphedema from peripheral edema?

  • Lymphedema can be easily concealed, while peripheral edema cannot
  • Lymphedema is caused by surgical removal of lymph nodes, while peripheral edema is not
  • Lymphedema is protein-rich, while peripheral edema is not protein-rich (correct)
  • Lymphedema is a temporary condition, while peripheral edema is lifelong
  • What happens to the remaining 10% of fluid in the circulatory system?

  • Composed of high-molecular-weight proteins and associated water (correct)
  • Does not contain proteins
  • Returns to the circulation via entry into venous capillaries

    Study Notes

    Lymphedema vs Peripheral Edema

    • Lymphedema is distinguished from peripheral edema by its chronic and irreversible nature, whereas peripheral edema is reversible and can be treated with diuretics and elevation

    Fluid Circulation

    • 90% of fluid returns to the circulation via the bloodstream, while the remaining 10% is drained by the lymphatic system
    • The remaining 10% of fluid in the circulatory system is drained by the lymphatic system, which plays a crucial role in maintaining tissue pressure and preventing edema

    Lymphatic System Function

    • The lymphatic system primarily serves to drain protein, excess fluids, and waste products from the interstitial space
    • 90-95% of fluid returns to the circulation via entry into venous capillaries
    • BCRL is characterized by chronic swelling of the arm, shoulder, or chest wall on the affected side following breast cancer treatment
    • BCRL can occur as a result of surgery, radiation, or chemotherapy, damaging the lymphatic vessels and nodes, leading to impaired lymphatic drainage
