Figures & data
Figure 1. A 25-year-old woman presented with a recurrent tumor in the left neck operation bed close to the esophagus and tracheoesophageal groove (a). Before RFA, a hydrodissection technique was applied to obtain a safety margin from the esophagus and recurrent laryngeal nerve (b). An RF electrode with a 0.4 cm size active tip was inserted into the recurrent tumor and the ablation was started (c). During ablation, the patient complained that her voice had changed. Ablation was stopped immediately and a cold dextrose solution was injected directly around the ablated tumor (d). After injecting 15 ml of cold dextrose solution, the patient’s voice completely improved (e).
Figure 2. A 55-year-old woman who presented with a large nodule in the left thyroid gland (a). Pre-ablation US evaluation revealed a medial type middle cervical sympathetic ganglion located close to the thyroid nodule (b,c). An RF electrode with a 1 cm size active tip was used for ablation (d). During ablation, ipsilateral conjunctival injection was detected, which is one of the early symptoms of Horner syndrome. Ablation was stopped immediately and a cold dextrose solution was injected directly into the perithyroidal area (e). After injection of 7 ml of cold dextrose solution, the patient’s symptoms had completely improved (e).
