PURPOSE: Clinically apparent haematomas are among most frequent complications after vacuum-assisted breast biopsy (VABB). We evaluated the prevalence and persistence of sonographically (US) detected haematomas and other tissue changes at the biopsy site after VABB. MATERIALS AND METHODS: We examined 48 women who underwent stereotactic 11G needle VABB; the majority of them had mammographically detected microcalcifications. US examination of the breast biopsy site was performed one week after the VABB in 48 patients, and in 45 patients once again three weeks after the VABB. In 13/45 patients US-guided fine needle aspiration biopsy (FNAB) of the changes visualised was performed 3 weeks after the biopsy. RESULTS: One week after the VABB, a haematoma at the biopsy site was detected in 45/48 (94 %) patients (mean length 16.3 mm, mean width 3.6 mm). Three weeks after the VABB, haematoma was detected in 25/45 patients (55 %) (mean length 9.3 mm, mean width 2.7 mm), and architectural distortion in 13/45 patients (29 %), in 7/45 patients (16 %), no changes were found. In 13 patients in whom FNAB (fine needle aspiration biopsy) was performed, haematoma was found in 6/13, fat necrosis in 3/13, reactive changes in 2/13, whereas 2/13 samples were unsatisfactory. CONCLUSION: The changes at the biopsy site can be seen by US in most of the patients one and three weeks after the VABB. These changes could potentially be used for US guidance and localisation of microcalcifications in patients requiring surgical biopsy.
