钼靶摄片立体穿刺定位乳腺活检术

Biopsy of needle stereotaction under mammography in nonpalpable breast lesion

目的 探讨X线立体穿刺钢丝标记定位活检术用于无体征的早期乳腺癌诊断的可行性。方法 对 18例钼靶X片上有可疑病灶而无任何临床体征的患者 ,在X线立体定位下穿刺病灶并用金属导丝标记 ,标记后根据导丝位置切除病灶 ,并进行快速冰冻活检 ,明确诊断。结果 18例中 ,7例恶性 ,11例良性。与术后病检报告一致。对无体征的早期乳腺癌诊断准确率均为10 0 %。结论 X线立体穿刺钢丝标记定位活检技术解决了只有影像学改变的乳腺病灶切除活检术中精确定位的难题 。

Objective To discuss the feasibility of diagnosis with needle stereotaction marking by steel wire under mammography and biopsy for nonpalpable early stage breast carcinoma.Methods Eighteen patients with doubtful nidus of breast only in X gram were performed needle stereotaction marking by steel wire under mammography, and removal freemartin biopsies of breast nidus were performed then.Results Localization and biopsy were very successful in all 18 patients. Seven patients were definited to have early stage breast carcinomas and eleven benign diseases.The diagnostic rate for nonpalpable early stage breast carcinoma was 100%.Conclusions Needle stereotaction marking by steel wire undermammography finish off the problem locating accurately breast nidus during operation.It was a credible and perfect technique for diagnoses of nonpalpable early stage breast carcinoma.
