高频彩超引导下定位针定位联合体表标记在手术切除乳腺小结节的应用价值

目的：探讨高频彩超引导下置留定位针定位联合体表标记在手术切除乳腺小结节的应用价值。方法参考美国放射学会制定的乳腺影像报告和数据系统，将诊断为BI-RADS3级、4级或5级的122个临床触诊不清的乳腺小结节在高频彩超引导下定位针定位联合体表标记后行手术切除。结果术前在高频彩超引导下对106例女性患者的122个病灶均一次定位成功，低回声结节大小0.4-1.5cm，所有病灶连同定位导丝完整切除，均送术中病理检查。病理证实良性病灶107个（87.7%），其中非典型增生14例；恶性病灶15个（12.3%），其中浸润性导管癌8例，导管内癌3例，腺癌3例，髓样癌1例。结论高频彩超引导定位针定位联合体表标记法定位准确，操作简单，创伤小，并发症少，缩短了手术时间，使临床触诊不清的乳腺小结节早期能够得到准确切除，值得在临床上推广和应用。

High frequency ultrasound guided positioning needle localization and marking application value in the operation resection of breast nodules

Objective To explore the value of the high frequency ultrasound guided indwelling positioning needle localization combined with marking application in the operation resection of breast nodules. Methods Breast imaging reporting and data sys-tem for reference America Radiological Society of the diagnosis for BI-RADS3 4 or 5 grade or 122 non palpable breast nodules needle localization in the high frequency ultrasound guided resection combined with surface markers were removed. Results Be-fore operation in high frequency ultrasound guidance in 106 cases of female patients with 122 lesions were located successfully , hypoechoic nodule size 0.4-1.5cm,all lesions with wire localization and complete resection,were sent for pathological examination during the operation. Pathology of benign lesions in 107（87.7%）,including 14 cases of atypical hyperplasia;malignant lesions in 15 （12.3%）,of which 8 cases of infiltrating ductal carcinoma,3 cases of ductal carcinoma,3 cases of adenocarcinoma,1 cases of medullary carcinoma. Conclusion High frequency ultrasonography guided positioning needle combined with marking method of accurate positioningis,simple operation,less trauma,less complications,shorten the operation time,early to make nonpalpable breast nodules can be accurately removed,is worthy of clinical popularization and application.
