Quantitative lymphoscintigraphy effectively assesses lymphatic system function in chronic limb edema patients. This radioisotopic method aids in understanding lymphoedema origins and early pathophysiology.

Area of Science:

  • Nuclear Medicine
  • Lymphology
  • Medical Imaging

Background:

  • Chronic limb edema is a significant clinical challenge.
  • Understanding lymphatic system dynamics is crucial for diagnosis and treatment.
  • Early detection of lymphatic dysfunction can improve patient outcomes.

Purpose of the Study:

  • To evaluate the state and dynamics of the lymphatic system in patients with chronic limb edema.
  • To correlate quantitative lymphoscintigraphy findings with lymphoedema etiology.
  • To explore the potential of quantitative lymphoscintigraphy as an early indicator of lymph pathophysiology.

Main Methods:

  • Utilized a radioisotopic method involving interstitial injections of 99mTc-sulphur microcolloid.
  • Scans were performed on 92 patients with chronic limb edema and 12 controls using a LFOV camera and data processor.

  • Quantitative indices of clearance and lymph node uptake were analyzed.

    • Main Results:

    • Quantitative indices showed good correlation with lymphoedema etiology.
    • Findings correlated with control subjects and healthy limbs in unilateral cases.
    • The method demonstrated feasibility in assessing lymphatic function.

    Conclusions:

    • Quantitative lymphoscintigraphy is a feasible indicator of early lymphatic pathophysiology changes.
    • Results support the hypothesis that lymphoedema often originates from congenital pathology.
    • This technique aids in understanding the underlying causes of chronic limb edema.
