| 摘要: |
| 目的 探讨影响甲状腺结节超声引导下细针抽吸活检（ultrasound-guided fine-needle aspiration, US-FNA)成功率的超声特征。方法 分析2016年9月～2018年8月就诊于我院行US-FNA的251个结节。分析其超声特征：大小、位置、钙化类型、钙化比例、实性比例，依据Bethesda分类标准，Bethesda Ⅰ类为无效，Bethesda≥Ⅱ类为有效，分析相关超声特征对FNA的影响。结果 US-FNA结果无效率：大小中A1组（0.5cm≤d＜1cm）最高42.4%（36/85）；位置中C2组（深层）最高41.9%（26/62）；钙化类型中C3组（粗钙化）最高49.1%（27/55）；钙化比例中D4组（50%＜C-R≤75%）、E4组（75%＜C-R）较高，分别为75.0%（15/20）、80.0%（8/10）；实性比例中A5组（0%＜S-R≤25%）、B5组（25%＜S-R≤50%）较高，分别为83.3%（5/6）、80.0%（4/5），上述无效较高组与各自超声特征类别中其他组相比差异有统计学意义（P＜0.05）。结论 甲状腺结节大小0.5cm≤d＜1.0cm、位置位于深层、粗钙化、钙化比例C-R＞50%、实性比例S-R≤50%时，在一定程度上会影响US-FNA结果不满意。 |

| Abstract: |
| Objective To investigate the influence of ultrasound characteristics of thy- roid nodules on the success rate of ultrasound-guided fine-needle aspiration. Methods Analysis of 235 cases of 251 nodules in our hospital from October 2015 to November 2017.The ultrasonographic features were analyzed: size, location, calcification type, calcification ratio, and solid proportion. According to the classification standard of Bethesda, Bethesda class I is invalid and Bethesda ≥ Ⅱ are valid. Analysis of the influence of correlated Ultrasonic characteristics on FNA. Results Size: group A1 (0.5cm≤d＜1cm)US-FNA had the highest inefficiency of 42.4% (36/85).Compared with the other three groups, the difference was statistically significant(P＜0.05). Depth: group C2(deep level） US-FNA had the highest inefficiency of 41.9% (26/62).Compared with the other two
groups , the difference was statistically significant(P＜0.05).Calcification type: group C3 (coarse calcification) US-FNA had the highest inefficiency of (49.1%) (27/55).Compared with the other two groups, the difference was statistically significant (P＜0.05). Calcifi- cation ratio: the inefficiency of US-FNA were 75.0% (15/20) and 80.0% (8/10) higher in D4 group (50%＜C-R≤75%) and E4 group (75%＜C-R).Compared with the other three groups, the difference was statistically significant(P＜0.05).Solid ratio: The inefficiency of US-FNA were 83.3%(5/6)and 80.0%(4/5)higher in A5 group(0%＜S-R≤25%)and B5 group(25%＜S-R≤50%).Compared with the other two groups, the difference was statisti- cally significant(P＜0.05). Conclusion The size of thyroid nodules 0.5cm ≤ d < 1.0 cm, the location is deep, coarse calcification, calcification ratio C-R > 50, solid ratio S-R ≤ 50, to some extent will affect the results of US-FNA unsatisfactory. |
