CAMARGO JUNIOR, Hélio Sebastião Amâncio de et al. Evaluation of a portable device for vacuum-assisted biopsy of breast microcalcifications. Radiol Bras [online]. 2010, vol.43, n.2, pp.109-112. ISSN 1678-7099.

OBJECTIVE: Vacuum-assisted biopsy is the percutaneous technique of breast biopsy with the lowest underestimation rate. However, the cost of such procedure is high and currently there is a considerable interest in developing less expensive techniques. The present study was aimed at testing a less expensive device for vacuum-assisted biopsy of breast microcalcifications. MATERIALS AND METHODS: Thirty-five patients with clustered microcalcifications classified as BI-RADS® 4 or 5 were submitted to biopsy. Collected specimen appropriateness, difficulties in the reinsertion of the cannula and number of biopsy passes were evaluated. RESULTS: Successful specimens collection was achieved in all of the patients. Histo-radiological disagreement, difficulties in the cannula reinsertion or severe complications were not observed. CONCLUSION: The authors conclude that the method is effective in terms of specimens appropriateness and cost-benefit ratio as compared with of biopsy techniques for breast microcalcifications. Such findings are compatible with data reported in the literature.
