数字化三维立体导丝定位穿刺技术在乳腺微小病灶中的应用

目的:探讨数字化三维立体导丝定位穿刺术对乳腺微小病灶的诊断价值。方法:回顾性分析临床触诊阴性而影像学表现异常的患者41例(乳腺微小病灶43处),41例均行乳腺数字化三维立体导丝定位穿刺切除并进行病理学检查。结果:43处微小病灶均定位成功,病变完全切除。病理检查:恶性病变8处,其中原位癌3处,浸润性导管癌Ⅰ～Ⅱ级3处,导管内癌伴早期浸润1处,浸润性导管癌伴腋下淋巴结转移1处;良性病变35处。结论:乳腺数字化三维立体导丝定位穿刺技术定位准确、损伤小、诊断符合率高,是治疗乳腺微小病变的重要手段,也是发现早期乳腺癌的重要方法。

3D guide-wire localization technique with digital mammography in the clinical application for minute breast lesions

Objective：To investigate the value of 3D guide-wire localization technique with digital mammography in the diagnosis of minute breast lesions.Methods：41 cases having imaging abnormalities yet with non-palpable breast lesions（43 lesions） underwent 3D guide-wire localization biopsy with digital mammography and pathologic diagnosis was obtained.The results were analyzed retrospectively.Results：All forty-three lesions were successfully localized and completely excised.The pathologic findings revealed eight malignant lesions including carcinoma in situ（n=3）,gradeⅠ~Ⅱ invasive ductal carcinoma（n=3）,intraductal carcinoma associated with early invasion and invasive ductal carcinoma with axillary lymph node metastasis for 1 lesion each.Benign lesions were found in 35 sites.Conclusion：Precise localization with mild trauma and accurate diagnosis could be provided by 3D guide-wire localization technique with digital mammography,which is an important approach for treating minute breast lesion as well as detecting early breast carcinoma.
