Analysis of ultrasound-guided fine needle aspiration in percutaneous biopsy of nodular goitre

Objective To analyze the efficacy of ultrasound diagnosis and results of ultrasound-guided fine-needle aspiration(US-FNA).Methods US-FNA was performed for 86 thyroid nodes in 49 patients.The diagnostic data obtained from US-FNA were compared with the ultrasound diagnosis.Results Two pieces of tissue were obtained from one nodule and the success ratio were 100%.Among these 86 thyroid nodules, US-FNA showed that 42 nodular goiter and the coincidence rate were 85.7%.7 cases were misdiagnosed(misdiagnosis rate 14.3%),among those were 2 Hashimoto's disease,1 subacute thyroiditis,2 thyroid papillary carcinoma and 2 thyroid adenoma.Post-puncture bleeding was not observed in all nodules.Conclusion Ultrasound-guided fine-needle aspiration(US-FNA)is accurate and reliable in diagnosing thyroid nodules.The US-FNA results can provide more information to the clinic.
