ABSTRACT Objective : To evaluate the efficacy and safety of percutaneous ethanol injection (PEI) in reducing the volume of cystic and mixed thyroid nodules. Materials and methods : A total of 36 patients with nodules treated with PEI and 13 individuals who declined PEI and were followed clinically or received other non surgical treatment (control group). Assessments were performed at baseline (immediately before treatment in the PEI group or evaluation of the nodule on ultrasonography in the control group) at […]

Percutaneous ethanol injection (PEI) guided by ultrasound has been used for the treatment of cystic, solid and autonomous thyroid nodules. We present our experience in the treatment of 50 patients with thyroid nodules: 26 solid, 17 cystic and 7 autonomous (AN). Patients were evaluated 1 week, 1, 3, and 6 months and 1 year after PEI. After one year, solid nodules showed a mean 74% volume reduction, and cysts a volume reduction of 92%, with no recurrences. After one year, […]
