X线三维立体定位术诊断临床检查阴性乳腺病变

目的 探讨乳腺X线三维立体定位术在临床检查阴性乳腺病变中的诊断价值.方法 64例患者因乳腺X线摄影检查发现可疑病变而接受立体定位术.利用乳腺三维立体导丝定位术和三维立体定位穿刺术对乳腺不能扪及的病变进行术前定位和旋切活检,术后行病理学检查.结果 64例患者中,62例定位满意,2例定位偏离,定位满意度96.88%.其中恶性病变10例,7例为导管原位癌(DCIS),良性病变54例.结论 乳腺三维立体定位技术可发现和诊断临床检查阴性的乳腺病变,有助于提高乳腺DCIS的检出率.

Diagnostic value of three-dimensional stereotactic localization for nonpalpable breast lesions

Objective To assess the diagnostic value of three-dimensional stereotatic localization in the breast lesions of negative clinical examination. Methods A total of 64 patients underwent X-ray examination and were suspected of breast diseases. Then three-dimensional stereotatic localization was performed. With the stereotatic wire localization and stereotactic core needle biopsy, the nonpalpable lesions were localized and removed. Pathological examination was done after the surgery. Results Three-dimensional stereotatic localization were well done in 62 patients (96.88%), while 2 patients deviated. Pathologic findings revealed that 10 patients were malignant (7 were ductal carcinoma in situ) and 54 patients were benign. Conclusion Three-dimensional stereotatic localization of breast contributes to the detection and diagnosis of nonpalpable breast lesions, increases the detection rate of the ductal carcinoma in situ.
