目的：探讨应用侧卧式X线立体定位导丝引导术对临床触诊阴性的乳腺微小病变的应用价值。方法：回顾性分析118例临床触诊阴性而乳腺摄片发现微小病变的患者，采用侧卧式X线立体定位引导术，将导丝滞留在病变处，外科医师将带有导丝的病变切除并送病理检查。结果：118例病灶一次性定位成功，定位成功率100%。测量留置导丝针尖端与目标靶点病灶的距离，定位满意111例（94%）。病变切除后标本摄片，病变切除率98.30%。经手术后病理证实，恶性病变45例（38.14%），其中原位癌29例，良性病变73例（61.86%）。结论：侧卧式X线立体定位导丝引导术可准确引导切检临床触诊阴性的乳腺微小病变、确定病变的性质、提高早期乳腺癌的检出率。
Abstract
Objective: To investigate the application value of X-ray stereotactic needle localized biopsy in the lateral decubitus position for nonpalpable breast lesions. Methods: Stereotactic mammography needle localized biopsies were performed on 118 cases with clinical nonpalpable breast lesions. After localization of lateral decubitus position, all cases received surgical resection according to the steel wire implantation left in the lesions and got pathological diagnosis. Results: The locations were successful once time in 118 cases, the success rate was 100%. The distance between the tip of the guide wire and the target of lesion was measured, and the satisfying positioning results were obtained in 111 cases(94%). After the lesion specimen radiography, the lesions removal rate was 98.30%. Postoperative pathology confirmed 45 cases of malignant lesions(38.14%), among which 8 cases were carcinoma in situ, and 73 cases of benign lesions(61.86%). Conclusion: X-ray stereotactic needle localized biopsy in the lateral decubitus position can accurately guide the surgical excision of nonpalpable breast minimal lesions and exactly diagnose lesions, which is helpful to improve the detection rate of early breast cancer.
