| PURPOSE : To evaluate the feasibility and efficacy of US-guided preoperative wire localization of nonpalpable
breast lesions.
MATERIALS and METHODS : US-guided preoperative wire localization was performed upon 45 nonpalpable breast lesions
including 14 nonpalpable masses, 11 nonpalpable masses with microcalcifications, 11 ductal lesions, 9
with microcalcifications. No local anesthesia was performed during the localization procedure. Under the USguidance,
the needle with the hook-wire was inserted into the lesion until the hook of the wire reached 1 cm beyond
the posterior margin of the lesion. Precise wire positioning was confirmed by mammography. Specimen
radiography or specimen ultrasonography was performed in all cases.
RESULTS : US-guided preoperative wire localization was successfully achieved in all cases. The time required for
US-guided wire localization was less than five minutes. All lesions were successfully removed by surgical excision.
Successful removal was confirmed by specimen radiography or specimen ultrasonography, gross findings
of the specimen and consistency between radiographic and pathologic findings. The histologic diagnosis of 45
lesions were 7 ductal carcinoma in situ, 8 invasive ductal carcinoma, 6 fibroadenoma, 8 intraductal papilloma, 2
atypical ductal hyperplasia, and 14 fibrocystic changes. No complications were occurred during and after the
procedure.
CONCLUSION : US-guided preoperative wire localization for excisional biopsy is simple, safe, and accurate method
in the histologic diagnosis of nonpalpable breast lesions detectable with ultrasonography |
