目的:评价超声引导下细针穿刺(US-FNA)对甲状腺良恶性结节的诊断价值。方法:对394个甲状腺结节行US-FNA检查,将穿刺诊断结果与手术病理及临床随访结果进行比较分析。结果:394个结节中,USFNA诊断为良性205个(52.0%),恶性115个(29.2%),可疑恶性25个(6.3%),涂片不满意49个(12.4%)。经手术病理和临床随访证实良性结节250个,恶性结节144个。去除涂片不满意者,计算USFNA诊断的敏感性为98.4%,特异性为94.0%,准确性为95.7%,阳性预测值为90.7%,阴性预测值为99.0%。结论:US-FNA敏感性、准确性高,且安全简便,对甲状腺良恶性结节诊断价值高。
Objective: To evaluate the diagnostic value of ultrasound-guided fine needle aspiration (US-FNA) in benign and malignant thyroid nodules. Methods: Thirty-six thyroid nodules were examined by US-FNA. The diagnostic results of the puncture were compared with the surgical pathology and clinical follow-up results. RESULTS: Among 394 nodules, USFNA was diagnosed as benign (52.0%), malignant (29.2%), suspicious malignant (6.3%) and smear-dissatisfied with 49 (12.4%). Surgical pathology and clinical follow-up confirmed 250 benign nodules, 144 malignant nodules. The results of USFNA were 98.4%, 94.0%, 95.7%, 90.7%, and 99.0%, respectively. Conclusion: The sensitivity and accuracy of US-FNA are high, and it is safe and simple. It has high diagnostic value for benign and malignant thyroid nodules.
