Lesions entirely removed during stereotactic biopsy: preoperative localization on the basis of mammographic landmarks and feasibility of freehand technique--initial experience.

Abstract

Seven patients with mammographic lesions entirely removed at percutaneous core needle biopsy that required wider excision underwent freehand localization of the site of the prior lesion with orthogonal and reproducible mammographic landmarks to guide needle placement. Successful excision was accomplished in all cases, as evidenced by similar histopathologic findings, fibrin bands or collagen, and core needle biopsy tract at microscopy.
