Methods and materials
63 patients (12 males,
41 females) underwent percutaneous thermal ablation for a benign thyroid nodule.
32 (4 males,
28 females) underwent treatment with RFA (,
and 31 (8 males,
23 females) underwent PLA under ultrasound guidance.
We used an internally cooled electrode with 17-18 gauge calibre and 0.5-1.5-cm active tip (AMICA,
HS Hospital Service,
Italy) and the moving-shot technique for RFA ablation.
We used a continuous-wave Nd-YAG laser operating at 1.064 mm (EchoLaser X4©,
Italy) for LA.
Mean nodule volume before ablation,
Time and energy deployed for ablation,
and volume percentage reduction at 1-2 months,
at 6 months and at 1 year were compared.
