RESUMO

Objective: Evaluate the reproducibility of the classifications of thyroid nodules vascularization with color Doppler described by Lagalla et al. and Chammas et al.. Methods: 265 thyroid nodules were studied with color Doppler and citopathology. Results: In the diagnosis of nodules with malignant citopathology, Chammass IV and V patterns showed sensibility of 16.7%, specificity of 97.6%, positive predictive value of 33.3%, negative predictive value of 94.1% and accuracy of 92.1%; Lagallas III pattern showed sensibility of 44.4%, specificity of 19.4%, positive predictive value of 3.9%, negative predictive value of 82.8% and accuracy of 21.1%. Conclusions: Lagallas classification showed low sensibility and accuracy in the detection of nodules with malignant citopathology, while Chammass classification showed high accuracy, but also low sensibility. Color Doppler was also insufficient to substitute fine-needle aspiration and the citopathologic study in the diagnosis of malignant thyroid nodules, but could aid in the decision of which nodules should be biopsied.
