目的评价全屏数字化乳腺机(FFDM)在外科术前定位隐匿性乳腺病灶的临床应用价值。方法24例经FFDM检查发现而临床不能触及的26个乳腺病灶在FFDM定位下穿刺,于病灶内留置导丝,指导外科手术活检。结果24例26个隐匿性病灶X线表现包括微钙化20个,局部结构紊乱2个、小结节4个。一次性定位满意率为92.3%。术中冰冻切片检查,6个病灶为恶性(占23.1%),临界性病变4个,16个为良性。结论应用FFDM行外科术前定位活检,方便、快捷、定位准确高,尤其在明确疑癌微钙化性质方面,是诸多术前定位法的首选。
Objective To evaluate the clinical value of full screen digital breast machine (FFDM) in the localization of occult breast lesions before surgery. Methods Twenty - six cases of breast lesions unresectable by FFDM were punctured in FFDM under the guidance of FFDM, and guide wires were placed in the lesion to guide the surgical biopsy. Results X-ray manifestations of 26 occult lesions in 24 patients included 20 micro-calcifications, 2 local structural disorders and 4 small nodules. One-time positioning satisfaction rate was 92.3%. Intraoperative frozen section examination, 6 lesions were malignant (23.1%), 4 critical lesions, 16 were benign. Conclusion Surgical preoperative biopsy using FFDM is convenient, rapid and accurate in positioning. It is the first choice of many preoperative localization methods especially in the definitive diagnosis of microcalcifications of suspected cancer.
