Objective: This study aims to examine all the interventional procedures performed with ultrasonography in our department, to determine the success rates, complications, advantages, and disadvantages of these procedures, and to review our findings with the literature.

Material and Method: From July 1999 to June 2004 in our mamography unit, out of 135 lesions (70 aspiration biopsies, 62 wire-guided excision biopsies, 3 trucut biopsies) that were localized preoperatively with ultrasonography-guided aspiration or needle (wire) localization biopsy in 115 patients, those that had results for histopathologic evaluation, were reevaluated retrospectively. The success rates of ultrasonography-guided interventional procedures were determined, and their complications were evaluated.

Results: Out of 70 aspirated lesions, 7 were considered unsuccessful because they resulted in being \"non-diagnostic material\", and 3 were considered unsuccessful because no material could be obtained from the lesion. It was observed that out of 60 lesions with successful aspiration, 57 (95%) lesions were diagnosed as benign and 3 (5%) lesions were diagnosed as malignant. According to the histopathological results of 62 wire-guided excision biopsies, 43 (69.4%) lesions were benign and 19 (30.7%) lesions were malignant. All 3 lesions that were biopsied with trucut needle were diagnosed as benign. During the procedures, no complications occurred other than mild vasovagal reaction in 2 patients (%1.5) and bleeding in 5 patients (%3.7) which was manageable with short-term compression.

Conclusion: The success rate of ultrasonography-guided interventional methods is high in our study. The accuracy of radiological methods is also high. Our results are consistent with the literature. Statistical studies and retrospective evaluation of lesions with histopathologic results increase the experience of diagnostic centers.
