高频超声引导下Mammotome旋切系统在乳腺微小钙化灶切取活检中的价值

Biopsy of breast microcalcification using high-frequency ultrasound-guided Mammotome Breast Biopsy System

目的探讨高频超声引导下M ammotom e微创旋切系统在乳腺微小钙化灶切取活检中的临床价值。方法在高频超声引导下应用M ammotom e系统对24例乳腺微小钙化灶施行微创旋切术,钙化灶切除后病理检查。结果24例病灶均被准确定位切取。24例乳腺钙化灶病理:乳腺癌3例(12.5%),其中导管原位癌2例,浸润性导管癌1例;乳腺良性病变21例(87.5%),其中囊性小叶增生9例,乳腺导管增生及扩张6例,硬化乳腺病5例,导管内乳头状瘤1例。结论高频超声引导下M ammotom e微创旋切系统诊断乳腺疾病安全可靠,微创,是诊断乳腺疾病的有效方法。

Objective To evaluate the clinical application of high-frequency ultrasound-guided Mammotome Breast Biopsy System in the biopsy of breast microcalcification. Methods The sterotactic biopsy of microcalcification in breast was performed under the guidance of high-frequency ultrasonography in 24 patients. Results The location of the lesion was accurately determined in all the 24 patients. Pathological findings showed malignant breast tumors in 3 patients （12.5%） and benign breast diseases in 21 patients （87.5%）. The malignant tumors included ductal carcinoma in situ in 2 patients and invasive ductal carcinoma in 1 patient. The benign diseases included cystic lobular hyperplasia in 9 patients, ductal hyperplasia and dilation in 6 patients, galactophore cirrhosis in 5 patients, and intraductal papilloma in 1 patient. Conclusions Use of the Mammotome Breast Biopsy System under the guidance of high-frequency ultrasonography is a safe and effective option for the diagnosis of impalpable breast lesions.
