Sonographically guided percutaneous excision of clinically benign breast masses

Purpose. To report our experience with a vacuum‐assisted biopsy device system in percutaneous excision of clinically benign breast masses under sonographic guidance. Methods. Percutaneous removal of 79 masses in 58 patients was performed with a vacuum‐assisted biopsy device under sonographic guidance from April 2008 to September 2008. The lesions were category 3 lesions on sonogram, according to Breast Imaging Reporting and Data System (n = 74), or had been confirmed as benign by a previous core needle biopsy (n = 5). Results. All procedures were technically successful. Confirmed as benign were 98.7% (78/79) lesions on pathology after resection, and 93.7% (74/79) lesions were excised completely as demonstrated by follow‐up sonographic examination. The duration of the procedure ranged from 2 to 19 minutes (mean ± SD, 9.6 ± 9.3). Conclusions. Percutaneous excision using a vacuum‐assisted biopsy device is an alternative to surgical excision of benign breast masses. © 2010 Wiley Periodicals, Inc. J Clin Ultrasound, 2011.
