乳腺X线立体定位导丝引导下对乳腺不可触及病灶活检术失败原因分析

Analysis of failure causes in mammography-guided wire localization stereotactic-biopsy of non-palpable breast lesions

目的:分析乳腺X线立体定位导丝引导下对乳腺不可触及病灶活检术失败的原因。方法:回顾总结分析我院181位患者的192例X线影像学表现异常而临床不可触及的乳腺病变,均行全数字化乳腺X线立体定位导丝引导下定位,由外科医生实施病灶切除,并将标本送回医学影像科摄片,判断可疑病灶是否全部或部分(选取有意义的部分)切除,否则需指导外科医生进行补切。结果:192例病灶中,一次成功切除目标病灶者176例,两次及两次以上才能完全切除目标病灶者13例,始终未能切除目标病灶者3例。结论:重视影响乳腺X线立体定位导丝引导活检术的成败因素,是提高定位成功率及定位准确性的保证。

Objective： To analyze the causes of failure in mammography-guided wire localization stereotactic-biopsy of non-palpable breast lesions. Methods： One hundred and eighty one patients with 192 lesions, which were non-palpable but positive in mammography, were analyzed retrospectively. All the lesions were performed mammography-guided wire localization and then were excised. The removed specimens were sent back to radiology department for mammography and estimated whether the suspected lesions were excised entirely or partially excised and whether re-excision was needed. Results： Among these 192 lesions, there were 176 lesions which were excised fully by one-stage operation. There were 13 lesions which were excised fully by two or more. And 3 lesions were not excised completely at the end. Conclusions： Pay attention to the impact factors is the guarantee of improving successful rate and precise localization of mammography-guided wire localization stereotactic-biopsy.
