DR.Guttler’s comments:

  1. 69 BTNs (mean volume 6.35±5.66 ml, range 1.00–25.04 ml) confirmed by fine-needle aspiration cytology (FNAC) in fifty-four patients were treated with ultrasound-guided percutaneous radiofrequency ablation (RFA) and the local treatment efficacy was immediately assessed by intra-procedural contrast-enhanced ultrasound (CEUS).
  2. Factors associated with initial ICA and initial ICA patterns on CEUS were assessed.
  3. Volume reduction ratios (VRRs) of ICA nodules were compared with those with complete ablation (CA).
  4. There were significant differences in VRRs between ICA nodules and CA nodules at the 3- and 6-month follow-up (all P < 0.05)
  5. The factors associated with initial ICA after RFA for BTNs were predominantly solid nodules, nodule close to danger triangle area, nodule close to carotid artery, and peripheral blood flow on color-Doppler ultrasound.
  6. CEUS assists quick treatment response evaluation and facilitates subsequent additional RFA and final CA of the nodules.
  7. Nodules with CA achieve a better outcome in terms of VRR in comparison with those with ICA.
  8. When I do thyroid RFA I plan to use the hydrodissection method to move targeted nodule away from a vital structure such as the carotid or recurrent nerve.
  9. Nodules with prominent blood vessels feeding it can be be ablated at the entry point to the nodule to prevent heat sink from decreasing needed heat to ablate the nodule.

  11. Ask for Alicia for details of thyroid RFA treatment.
