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

目的探讨高频超声引导下Mammotome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Mammotome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Mammotome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。

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

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.
