超声引导下乳腺小微病灶导丝定位的临床应用

Clinical application of preoperative ultrasound-guided guide-wire localization in diagnosing tiny breast lesions

目的探讨超声引导下乳腺小微病灶导丝定位的临床应用价值。方法对56例临床触诊困难的乳腺小微病灶,术前通过高频超声引导下导丝定位,后经手术循迹切除,并对相关资料进行回顾性分析。结果 56例病灶均定位成功并完整切除。病灶组织类型包括浸润性导管癌11例,导管内癌5例,小叶原位癌2例,黏液癌2例,纤维腺瘤24例,不典型增生6例,导管内乳头状瘤4例,浆细胞性乳腺炎2例。结论超声引导下乳腺导丝定位安全、可靠,对触诊不佳的乳腺小微病灶定位准确,能够帮助临床准确探寻病灶并完整切除,避免不必要的乳腺损伤,值得临床推广。

Objective To discuss the clinical application of ultrasound- guided preoperative guide-wire localization in diagnosing tiny breast lesions. Methods A total of 56 patients with impalpable tiny breast lesions were enrolled in this study. Preoperative guide- wire localization of the lesion was performed under high- frequency ultrasound guidance, which was followed by tracking resection of the lesion. The clinical data were retrospectively analyzed. Results Successful localization and complete resection of the lesion was accomplished in all 56 patients. The lesions included invasive ductal carcinoma（n =11）, intraductal carcinoma（n =5）, ductal carcinoma in situ（n =2）, mucinous carcinoma（n =2）, fibroadenoma（n =24）,atypical hyperplasia（n =6）, intraductal papilloma（n =4） and plasma- cell mastitis（n =2）. Conclusion Ultrasound- guided preoperative guide- wire localization is a safe and reliable technique for the diagnosis of impalpable tiny breast lesions. It can precisely localize the lesion, which is very helpful for making a complete resection of the lesion and avoiding unnecessary breast injury. Therefore, this technique should be recommended in clinical practice.
