Evaluation of Ultrasound-guided 8-Gauge Vacuum-assisted Excision System for the Removal of US-detectable Breast Lesions

AIM: To assess the ability of ultrasound (US)-guided vacuum-assisted breast excision (VAE) to remove Breast Imaging Reporting and Data System (BI-RADS) >/=3 breast lesions in order to analyze US features most frequently associated with complete excision. MATERIALS AND METHODS: A total of 266 BI-RADS >/=3 lesions without microcalcifications underwent US-VAE. US-VAE and gold standard pathological results were compared. US features of lesions were analyzed. RESULTS: The complete excision rate was 93.61%; the VAE agreement rate was 99.62%. Circumscribed margins, regular shape, parallel orientation, and the absence of posterior features were favorable US features associated with complete excision. Lesions completely excised were: BI-RADS 3
