Avaliação da indicação das biópsias de tireoide segundo a classificação TI-RADS

Abstract

Abstract: ultrasonographic evaluation of patients with pneumonia is fundamental and important for a Fine Needle Aspiration (FNAB) biopsy. Objective: To evaluate the cytopathologic results of thyroid biopsies performed by the ultrasound guided by fine needle aspiration (FNA) method, correlating with the criteria of the Thyroid Imaging Reporting and Data System (TI-RADS).

Materials and Methods: the present research was developed with the cross-sectional retrospective study, with a quantitative and indirect approach. The ultrasound reports of patients who underwent the FNA procedure was analyzed in a tertiary hospital in the north of Rio Grande do Sul. Results: 238 patients performed US thyroid in the service, however, 69 of these did not meet the study criteria. A total of 169 patients were evaluated, with a prevalence of females. The mean age was 52.5 ± 14.37 years, ranging from 18 to 86 years. In the age classification, 50 years was the one with the highest frequency. The highest frequency score was TR4 with 43 patients and the lowest frequency score was TR2. The cytopathological results presented mostly with unspecified cells 36, followed by colloid goiter in 8. In our study 4 cases of TI-RADS 4 patients with malignant cellularity were found.

Conclusion: considering the references used, the final results were similar and the TI-RADS proved to be important for decision making in relation to FNAB, being a safe classification both for indication of intervention and for the exclusion of benign nodules. The TI-RADS should be considered an appropriate classification in the evaluation of thyroid nodules and its uniformity has been shown to be important to avoid unnecessary fine needle aspiration puncture, besides helping in the decisions when to do it.
