富血供及乏血供甲状腺结节在超声引导下行US-FNAB时穿刺针口径选择的研究

Study on the Selection of Needle Caliber for US-FNAB Examination of Hypervascular and Hypovascular Thyroid Nodules

【目的】探讨富血供及乏血供甲状腺结节在超声引导下行细针穿刺活检(US-FNAB)时的穿刺针口径选择。【方法】选取2020年12月至2021年12月在陕西省森林工业职工医院行US-FNAB检查的107例甲状腺结节患者,均为单发结节。根据标本病理诊断结果分为满意组(共93个结节)与不满意组(共14个结节)。比较两组结节大小、位置、是否存在钙化及钙化类型、结节边缘形态、结节纵横比、结节回声、结节内部组成、周边组织血流分布情况等;比较不同血供类型使用不同口径穿刺针的标本满意率。【结果】满意组与不满意组性别、年龄、结节大小、结节位置、钙化类型、结节边缘、结节纵横比、结节回声、结节内部组成、穿刺针口径比较,差异无统计学意义(P>0.05);满意组富血供结节数量明显少于不满意组(P<0.05)。富血供结节中共21例使用23 G口径穿刺针,30例使用25 G口径穿刺针,25 G口径穿刺针标本满意率明显高于23 G口径穿刺针(P<0.05);乏血供结节中共31例使用23 G口径穿刺针,25例使用25 G口径穿刺针,23 G口径穿刺针标本满意率明显高于25 G口径穿刺针(P<0.05)。【结论】富血供结节使用25 G口径穿刺针得到的标本满意率更高,乏血供结节使用23 G口径穿刺针得到的标本满意率更高。

【Objective】To investigate the selection of needle caliber for ultrasound-guided fine-needle aspiration biopsy(US-FNAB)of hypervascular and hypovascular thyroid nodules.【Methods】A total of 96 patients with thyroid nodules who underwent US-FNAB examinations in our hospital from December 2020 to December 2021 were included in the study,with a total of 107 nodules.Based on the pathological diagnosis results,specimens were divided into the satisfactory group(93 nodules)and unsatisfactory group(14 nodules).During the ultrasound examination,parameters such as nodule size,location,presence,and type of calcification,nodule margin morphology,nodule aspect ratio,nodule echogenicity,internal composition of the nodule,and surrounding tissue blood flow distribution were recorded.Clinical data between the two groups were compared,as well as the specimen satisfaction rate with different calibers of needles for different blood supply types.【Results】There were no significant differences between the satisfactory and unsatisfactory groups in terms of gender,age,nodule size,location,type of calcification,nodule margins,aspect ratio,echogenicity,internal composition,and needle caliber(P>0.05).The number of hypervascular nodules in the satisfactory group was significantly less than that in the unsatisfactory group(P<0.05).Among the hypervascular nodules,21 used a 23 G needle and 30 used a 25 G needle,with the 25 G needle showing a significantly higher specimen satisfaction rate than the 23 G needle(P<0.05).Among the hypovascular nodules,31 used a 23 G needle and 25 used a 25 G needle,with the 23 G needle having a significantly higher specimen satisfaction rate than the 25 G needle(P<0.05).【Conclusion】The specimen satisfaction rate is higher for hypervascular nodules using a 25 G needle,while hypovascular nodules achieve a higher specimen satisfaction rate with a 23 G needle.
