Percutaneous ethanol injection therapy offers a safe and effective alternative for treating thyroid adenoma. This minimally invasive procedure successfully reduced nodule size and resolved hyperthyroidism in most patients.

Area of Science:

  • Endocrinology
  • Minimally Invasive Procedures
  • Medical Imaging

Background:

  • Thyroid adenoma management traditionally involves surgery or radiometabolic treatment.
  • Percutaneous ethanol injection (PEI) has emerged as a viable alternative for focal lesions.
  • PEI's efficacy in thyroid adenoma treatment requires further investigation.

Purpose of the Study:

  • To evaluate the effectiveness and safety of sonographically guided PEI for thyroid adenoma.
  • To assess the impact of PEI on nodule volume and thyroid hormone levels.
  • To determine the remission rates of hyperthyroidism post-PEI treatment.

Main Methods:

  • Sixty-nine patients with thyroid adenoma (toxic and pretoxic) underwent PEI.
  • Ethanol was injected weekly under sonographic guidance over 4-9 sessions.

  • Thyroid function, nodule volume, and structural changes were monitored during and after treatment.
  • Main Results:

    • 80% of toxic adenoma patients achieved biochemical and clinical hyperthyroidism remission.
    • Significant nodule volume reduction (70-80%) was observed in all patients.
    • PEI demonstrated a favorable safety profile with only transient side effects.

    Conclusions:

    • Sonographically guided PEI is an effective and safe treatment for thyroid adenoma.
    • PEI induces significant nodule shrinkage and functional ablation.
    • This technique presents a valid alternative to conventional thyroid adenoma therapies.
