PURPOSE: We performed add-on type stereotactic vaccum-assisted breast biopsy (SVABB) with the patient in the decubitus position and we determined the feasibility of SVABB according to the breast thickness, the vicinity of the lesion in relation to the chest wall and the histopathologic diagnosis, and we report here on our initial experience. MATERIALS AND METHODS: 81 patients with 82 lesions underwent SVABB. We measured the distance of the lesion from the chest wall on the basis of mammography, and we evaluated the breast thickness on the basis of the magnified, stereotactic view. The histopathologic results and the rate of underestimating atypical findings and ductal carcinoma in situ were analyzed. RESULTS: The range of breast thickness was 12~61 mm on the magnified view and the range of breast thickness was 16~55 mm on the stereotactic view. The range of the distance of the lesion to the chest wall was 0~67 mm. The histopathologic results of SVABB demonstrated benign findings for 62 lesions, atypical findings for 10 lesions, ductal carcinoma in situ for 8 lesions and invasive ductal carcinoma for 2 lesions. The estimated underestimation rate was 30% (3/10) for the atypical finding and 0% (0/7) for ductal carcinoma in situ. CONCLUSION: This study demonstrated the results of add-on type SVABB with the patient in the decubitus position and SVABB was successful for patients with various lesion locations and breast thicknesses.
