摘　　要：目的研究钼靶X线导丝定位术在乳腺微小病变手术中的应用价值。方法本组共29例,术前钼靶X线照相诊断泥沙样钙化17例,小结节及结节样病变12例。使用专用乳腺病变定位设备,对病变部位进行左右24度角定位照相,专用设备上读取片中标记点及病变中心点确定穿刺部位,穿刺后再次拍片确定导丝是否到达病变位置。手术后对切除组织进行照相,确定病变部位是否被完全切除,而后送病理科检验。结果经定位术后,病变切除率100%。病理结果乳腺癌15例,纤维腺瘤8例,原位癌4例,高度可疑癌2例。结论29例患者中,病理诊断乳腺癌及高度可疑癌病例21例(72.4%)。采用钼靶X线导丝术前定位,对乳腺泥沙样钙化灶及小结节病变的处理具有很高的实用价值。Objective：To study the value of guide-wire technique under stereo-mammography in the pre-surgical localization of non-papable breast lesion. Methods：29 patients with the age ranged from 34 to 62 years old were included. The mammographic findings were sand-like calcifications （n=17） and small nodule or nodule-like lesion （n= 12）. Dual 24° stereo-mammography localization of the lesion were undertaken with a specific localization system and the puncture point was selected according to the marker and the center of lesion. Mammogram was taken after guide-wire insertion to ensure if the guide-wire was at the right position. Mammogram of the resected specimen was again undertaken after surgical resection to confirm whether the lesion was completely removed. Pathology diagnosis of removed tissue was obtained. Results： The lesions were 100% removed after the guide-wire localization procedure. The pathology diagnosis were breast cancer （n= 15）, fibroadenoma （n= 8）, carcinoma in situ （n = 4 ）, and highly suspicious carcinoma （ n = 2 ）. Conclusion： Of the 29 cases with non-palpable breast lesion having pre-surgical guide-wire localization under stereo-mammography, 21 cases （72.4 %） had pathology diagnosis as breast cancer and suspicious carcinoma, which proved that this technique was highly significant in the clinical practice for non-palpable breast lesion.
