Abstract:
PURPOSE: Stereotactic vacuum-assisted breast biopsy (SV AB) has recently been introduced as an alternative to the traditional surgical excisional biopsy with needle localization (NLBB). Although SVAB has excellent sensitivity and specificity with very low false negative results, patients might complain about the uncomfortable table and the painful breast compression that is done during SVAB. Furthermore, the cost of SVAB is too expensive to be widely adopted in Korea. So we developed a new technique of vacuum-assisted breast biopsy with air localization (VAB-AL) for the patients suffering with microcalcifications. METHODS: From April 2005 to Oct 2005, 10 microcalcification patients, whose lesions were difficult to be seen on breast ultrasonography, underwent vacuum-assisted breast biopsies with air localization (VAB-AL). First, classical NL was done to localize the mammographic abnormalities. Instead of insertion of the wire, 1 cc amounts of air were injected through a needle. The injected air could be easily visualized as a hyperechogenic density on breast sonography. Vacuum-assisted breast biopsy for the air-induced hyperechogenic densities was then done under sonographic guidance. The specimen radiography was performed to confirm that the lesion was removed. RESULTS: The mean age of the patients was 46 (range: 37~55). The upper-outer quadrant of the breast was the most common site of the lesions (6/10, 60%); the upper-inner quadrant (2/10, 20%), and then the lower-inner quadrant (1/10, 10%) followed. The specimen radiology for all 10 patients showed that the mammographic abnormalities were successfully removed. The most common pathologic type was fibrocystic disease (6/10, 70%); intraductal carcinoma (3/10, 30%), and then atypical ductal hyperplasia (1/10, 10%) followed. There were no major complications. CONCLUSION: Vacuum-assisted breast biopsy with air localization is a new technique that can minimize the complaints of patients with microcalcifications about the uncomfortable table, the painful breast compression and the economic burden of SVAB. This new procedure was successfully performed in our 10 patients, and we believe this procedure shows a lot of promise as one of alternatives to classical NLBB and SVAB.
