超声引导美蓝着色定位触诊阴性乳腺病变的临床应用

目的探讨超声引导下术前美蓝着色定位在触诊阴性乳腺病变的临床应用价值。方法本组对62例女性患者的81个触诊阴性乳腺病变,术前超声检查判断其病变性质,并于术前超声引导下注射美蓝着色于肿块周缘或肿块内精确定位,外科手术治疗并作病理检查。结果 81个触诊阴性乳腺病变均完整切除,其中良性病灶69个,恶性病灶12个。对比病理结果,超声诊断触诊阴性乳腺癌的灵敏度为83.88%(10/12),特异度为95.65%(65/69)。结论超声引导下术前美蓝着色定位迅速、创伤小,对指导手术完整切除触诊阴性乳腺病灶具有较高的临床应用价值。

Clinic value of ultrasound guidance for methylene blue stain in localization of non-palpable breast lesions

Objective To evaluate the role of ultrasound guidance for methylene blue stain in localization of non-palpable breast lesions.Methods Sixty-two female patients with 81 non-palpable breast lesions were examined with ultrasound preoperatively.The methylene blue were injected in and around the lesions under the guidance of ultrasound.All lesions were resected and examined pathologically.Results All 81 cases were resected and there were 69 benign masses and 12 malignant tumors.Compared with the pathological results,the sensitivity and specificity were 83.88%（10/12） and 95.65%（65/69）for ultrasound diagnosis non-palpable breast lesions.Conclusion It is valuable for ultrasound guidance of methylene blue stain in the treatment of non-palpable breast lesion with advantages of quick localization and less invasiveness.
