摘要:
【摘要】〓目的〓探讨甲状腺结节超声引导细针穿刺(USFNAB)无效的相关超声图像特征。方法〓回顾分析2011年3月~2012年5月行USFNAB的200例甲状腺结节,参照细胞病理学Bethesda标准,将穿刺结果分为穿刺无效和穿刺有效两类,分析其超声图像特征与穿刺无效的关系。结果〓影响甲状腺结节USFNAB穿刺无效率的超声特征包括:伴有粗大钙化的结节(P=0018)、血流丰富的结节(P=0029)、血流环绕结节的外周分布(P=0004)、位置较深的结节(P=0038)、结节邻近重要结构(P<0001)、穿刺前超声诊断良性的结节(P=004)、伴有亚急性甲状腺炎背景的结节(P=0029)和最大径线<10mm的结节(P=0013)。结论〓了解容易导致甲状腺结节USFNAB穿刺无效的超声图像特征,是加强针对性训练和提高穿刺水平的重要环节。

Abstract:
【Abstract】〓Objective〓To evaluate the ultrasonographic features of thyroid nodules related to inefficient operations of ultrasoundguided fineneedle aspiration (USFNAB). Methods〓 The ultrasonographic features and cytopathology results after USFNAB of 200 thyroid nodules from March 2011 to May 2012 were retrospectively analyzed. Based on the cytopathology results guided by Bethesda system, the operations of USFNAB with satisfactory and unsatisfactory samples were defined as efficient and inefficient respectively. The relationship between ultrasonographic features and inefficient operations were assessed. Results〓 The ultrasonographic features significantly related to inefficient operations were macrocalcification (P=0018), rich inner blood flow (P=0029), surrounding blood flow (P=0004), deep location(P=0038), peripheral vital structures(P<0001),benign prediction by ultrasonography (P=004), subacute thyroiditis background(P=0029) and nodule size smaller than 10mm ( P=0013). Conclusion〓 It is important to recognize the ultrasonographic features related to inefficient operations to make intensive training and achieve efficient operation in USFNAB of thyroid nodules.
