目的：评价超声弹性成像技术联合麦默通在治疗乳腺良性肿块中的临床价值。方法：回顾分析78例经病理证实的乳腺良性肿块患者（125枚肿块）的临床资料，患者均行超声引导下麦默通微创旋切术，术前均行超声弹性成像检查。术后观察患者有无发热、局部疼痛、红肿、血肿等并发症；术后3~6个月随访有无残留，SPASS 16.0进行统计分析。结果：125枚肿块完整切除，每个肿块的平均切除时间为6 min，平均旋切次数为10次。术后病理结果：单纯纤维腺瘤46枚（36.8%），乳腺腺病伴纤维腺瘤74枚（59.2%），导管内乳头状瘤2枚（1.6%），其他包括乳腺腺病伴导管扩张、乳腺慢性炎、腺病伴导管上皮增生活跃各1枚。术后疼痛8例（10.3%），红肿6例（7.7%），血肿2例（2.6%）；术后6例（7.7%）有残留，残留与肿块的大小及数目有关（P=0.043、0.027），而与肿块的弹性评分、病理类型以及术后的并发症无明显相关性。结论：超声技术联合麦默通对治疗乳腺良性肿块有重要的临床价值。
