超声引导下甲状腺钙化结节细针穿刺细胞学无法诊断率的分析

Evaluation of the inadequate diagnostic rate of ultrasound guided fine needle aspiration cytology in thyroid calcified nodules

目的 探讨超声引导下甲状腺钙化结节细针穿刺细胞学的无法诊断率.方法 回顾性分析2013年3至10月浙江大学医学院附属第一医院202例患者208个甲状腺钙化结节及细胞学诊断结果.结果 208个甲状腺钙化结节细针穿刺检查均未出现严重并发症.甲状腺钙化结节无法诊断率为25.5％;微钙化、粗钙化、周边弧型钙化结节的无法诊断率分别为16.0％、26.4％、76.5％;周边弧型钙化结节比微钙化、粗钙化结节的无法诊断率均高（P＜0.01）,粗钙化与微钙化结节无法诊断率比较差异无统计学意义;不同大小（＜5 mm、5 ～10 mm、≥10 mm）各型钙化结节在无法诊断率上差异无统计学意义.结论 周边弧型钙化结节无法诊断率高,需尽量避免该类型钙化结节的穿刺.

Objective To evaluate the inadequate diagnostic rate of ultrasound guided fine needle aspiration cytology（USFNAC） in thyroid calcified nodules.Methods 208 thyroid calcified nodules in 202 patients were retrospective analyzed,and all of the nodules were acquired cytological diagnosis.Results There was no significant complication in the all 208 thyroid calcified nodules.The inadequate diagnostic rate was 25.5％ in thyroid calcified nodules.The inadequate diagnostic rates in micro calcifications,macro calcifications and circumjacent arc calcifications were 16.0％,26.4％ and 76.5％.The inadequate diagnostic rate in circumjacent arc calcifications were higher than those in micro calcifications and macro calcifications（P ＜ 0.01）,and the rates were no significance in micro calcifications and macro calcifications.There was no statistical significance in different size of thyroid calcified nodules.Conclusions The inadequate diagnostic rate in circumjacent arc calcifications was higher,and should to avoid USFNAC in these nodules.
