Two-year follow-up of stereotactically guided 9-G breast biopsy: a multicenter evaluation of a self-contained vacuum-assisted device.

Purpose: To evaluate the performance of a self-contained, battery-driven, vacuum-assisted breast biopsy (VABB) system for the sampling of clustered breast microcalcifications and masses under stereotactic guidance.

Methods And Materials: A total of 144 patients (median age: 56 years; range: 21-87 years) in four European breast centers underwent percutaneous 9-gauge (G), stereotactic-guided VABB. The median lesion size was 11 mm (range 2-60 mm).
