Abstract

e13034 Background: To validate the ultrasound-guided vacuum-assisted breast biopsy system (Mammotome) for diagnosis and minimally invasive excision of calcification in breast. Methods: In 20 patients, breast calcification lesions diagnosed by mammography were excised by ultrasound-guided Mammotome system with 8-gauge probe. The samples were taken mammography and followed by pathological examination. Results: All lesions were removed accurately and thoroughly with satisfactory cosmetic outcomes. No clinically significant hematoma developed. Each mass was resected through 9.15±2.70 cores on average over a mean of 11.65±3.88 minutes. Two cases of them were histologically diagnosed as ductal carcinoma in situ and 8 cases were fibroadenoma and 10 cases were adenosis. Conclusions: Ultrasound-guided Mammotome system can profit to diagnose and treat breast calcification lesions which is ultrasound positive. Ultrasound detection rate of microcalcifications is up to the instrument resolution and the operator's experience and patience.
