Abstract

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. 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. 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 ≤21.10 mm and BI-RADS 4 ≤18.70 mm with one unfavorable US characteristic, and BI-RADS 4 lesions ≤13.5 mm with two unfavorable US features hindered complete removal. Two atypical ductal hyperplasias (<10 mm, one unfavorable feature) and eight ductal carcinomas in situ (≤8.7 mm, one/two unfavorable features) were completely removed. US-VAE is highly accurate for diagnostic purpose and, in some cases, highly successful for complete lesion excision. This success also depends on the US characteristics and size of the lesion.
