Abstract:
Objective To investigate the value of multipoint and multidirectional ultrasound-guided fineneedle aspiration cytology (US-FNAC) in preoperative diagnosis of papillary thyroid microcarcinoma (PTMC).Methods From Jan.2012 to Jan.2013,multipoint and multidirectional US-FNAC were performed in 177 patients with 233 nodules suspected as PTMC,and the cytopathological findings were compared with surgical pathological results and clinical follow-up results.Results Of the 233 biopsies,the cytology were classified as malignant for 146 lesions,suspicious for malignancy for 43 lesions,benign for 24 lesions,follicular lesions for 4 lesions and inadequate sample for 16 lesions.After the second multipoint and multidirectional US-FNAC,only 1 case did not have sufficient cells for diagnosis,and the puncture failure rate was 0.43％.Actually there were 189 malignant and 44 benign lesions confirmed by clinical follow-up and pathological results.The sensitivity,specificity,and accuracy of multipoint and multidirectional US-FNAC was 99.5％,81.8％ and 96.1％ respectively.Conclusions Multipoint and multidirectional US-FNAC has definite value in increasing puncture qualified rate and positive diagnosis rate before operation.
