ABSTRACT Objective: Percutaneous ethanol injection (PEI) is an alternative to surgery for the treatment of thyroid nodules (TNs). However, size reductions of treated (TTNs) and untreated TN (UTNs) have not been compared. Volumetric reductions in TTNs with PEI were evaluated by comparing TTNs and UTNs in the same patient, and independent variables predicting good post-PEI outcomes were analyzed. Materials and methods: Overall, 282 patients with multinodular goiters were selected. Two nodules located in different lobes were compared for common disease […]

Thyroid nodular disease is a common clinical disorder mainly in iodine lacking regions. This study has evaluated the effectiveness of percutaneous ethanol injection (PEI) in the treatment of single, multiple, solid, and cystic thyroid nodules of different sizes with or without glandular dysfunction, in goiter endemic region. Forty-two patients with diagnosis of colloid goiter or colloid nodular hyperplasia in fine-needle aspiration (FNA) were selected for analysis, after having been submitted to at least two PEI. Thyroid nodules were multiple (solid […]

To verify the effectiveness of percutaneous ethanol injection (PEI) in the treatment of thyroid nodules (TN), we analyzed 86 TN from 77 patients before and after one or two sessions of PEI. The medians of the initial and final volumes were: 3.5 mL (range 0.3

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, […]
