A complication involving a braided hook-wire localization device

At the authors' institution, needle localization of breast lesions with a braided hook wire involves the wire being cut 1-2 cm from the point of entry before dissection, to avoid contamination of the sterile field with the nonsterile portion of wire. During dissection, the wire is brought through the skin into the area of dissection. In one patient, fragments of wire filaments were left within the breast. Braided hook wires must be cut cleanly, the cut surface should be wiped before dissection, and the surgical area should be cleansed before closure.
