目的探讨钼靶立体定位麦默通手术在乳房钙化灶诊断中的应用。方法收集2007年11月至2008年12月北京大学第三医院院收治的21例未触及乳房肿物的乳房钙化灶病例,年龄28～67岁,平均46.6岁。行钼靶立体定位麦默通穿刺活检手术。结果共切除乳房钙化灶29个。其中15个病灶为局限性簇状钙化灶,直径≤1cm,15个局限性钙化灶均完整切除。4例病人5个病灶病理证实为导管内癌,其余24个病灶病理证实为乳腺增生症,7个病灶表现为纤维囊性增生,有3个病灶伴有不同程度的导管上皮增生,1例伴有乳头状瘤形成。术后1例发生了穿刺部位血肿,自然吸收。全部病例均得到随访,平均9个月,4例乳腺癌病人行乳房切除,无复发,其余17例穿刺部位无肿块及陈旧血肿,3例复查钼靶未见可疑恶性征象。结论钼靶立体定位引导麦默通穿刺手术诊断乳房钙化灶,准确、微创、安全。
Objective To investigate the clinical application of mammotome positioning mammotome in the diagnosis of breast calcification. Methods A total of 21 breast calcification cases without breast masses were collected from November 2007 to December 2008 in the Third Hospital of Peking University. The age ranged from 28 to 67 years with an average of 46.6 years. Molybdenum target stereotactic Maimo Tong biopsy. Results A total of 29 breast calcifications were excised. Among them, 15 lesions were localized cluster calcification, with a diameter of ≤1 cm, and 15 limited calcifications were completely resected. The pathological diagnosis of 5 lesions in 4 patients was intraductal carcinoma, and the remaining 24 lesions were confirmed as hyperplasia of mammary glands. The 7 lesions showed fibrocystic hyperplasia. There were 3 lesions with different degrees of ductal hyperplasia and 1 with Have a papilloma formation. One case of postoperative hematoma at the puncture site, natural absorption. All cases were followed up for an average of 9 months. Four cases of breast cancer underwent mastectomy without recurrence. The remaining 17 cases had no mass or stained hematoma at the puncture site. No suspicious malignant signs were observed in 3 cases. Conclusion Molybdenum target stereotactic guide MacMiton puncture in the diagnosis of breast calcification, accurate, minimally invasive, safe.
