目的:应用乳腺X射线机及其配套的二维定位装置导丝定位指导手术切检,探讨对不可触及的乳腺微小病变单纯成簇钙化进行定性诊断的价值。方法:乳腺X射线片显示乳腺单纯成簇钙化灶〔钙化点>(3～5)个/cm2〕,X射线引导下定位并用导丝标记钙化的位置;标记后根据导丝锚定位置切除病变,并进行快速冰冻活检,明确诊断。结果:68例患者中,成功定位65例,导丝放置准确率为95.6%。定位过程中晕厥3例,1例出现气胸并发症。病理诊断恶性病变24例(35.3%),良性病变44例(64.7%)。结论:对于乳腺X射线摄影发现的单纯成簇状钙化,在乳腺X射线导丝定位系统引导下进行切除活检,是提高早期乳腺癌诊断率并指导临床治疗的有效手段。
OBJECTIVE: To evaluate the value of breast cancer X-ray machine and its associated two-dimensional positioning device for guide wire positioning guided surgery to investigate the qualitative diagnosis of simple cluster calcifications of non-palpable breast lesions. Methods: Mammary gland radiographs showed calcification (> 5-3 calcification points / cm2) in breast tissue. The specimens were placed under the guidance of X-ray and labeled with a guide wire. The lesions were removed according to the anchoring position of the guide wire , And rapid frozen biopsy, a clear diagnosis. Results: Of the 68 patients, 65 cases were successfully located and the accuracy of placement of guide wire was 95.6%. Positioning syncope in 3 cases, 1 case of pneumothorax complications. Pathological diagnosis of malignant lesions in 24 cases (35.3%), benign lesions in 44 cases (64.7%). CONCLUSIONS: Simple clustered calcifications found in mammography and biopsy under the guidance of mammographic X-ray guide system are effective methods to improve the diagnosis rate of early breast cancer and guide the clinical treatment.
