高频超声在硅胶乳房植入物检测中的价值

目的 探讨高频超声在硅胶乳房假体检测中的价值。方法 对７例妇女接受硅胶乳房假体植入术后，硅胶乳房假体破裂的１４也房采用７．５～１０．０ＭＨｚ的高频超声检测，均做了植入物清除术，获手术证实。结果 硅胶乳房假体完整的超声图像特征为：假体切面形态呈倒三角形，轮廓线平直，内部呈均匀一致的无回声表现，前壁表现为厚约１ｃｍ的稍强回声带。硅胶乳房假体破裂超声表现为植入物形状改变，囊壁局部膨隆，囊内见细小点状回声

The value of hyperfrequency ultrasound in silicone breast implants

Objective To determine the value of breast hyperfrequency ultrasonography (US) in the assessment of silicone breast implants.Methods Fourteen implanted breasts of 7 women underwent hyperfrequency US and were surgically removed.Results The ultrasonographic characteristies of an intact implant was showed that shape looks like updown triangle,contour line was straight,there was noice within the implant,the anechoic structure had a band of reverberations anteriorly.The sonographic findings with intracapsular rupture were:the implant shape transformed,echogenic noise,low level homogeneous echoes,and a contourbulge,horizountl lines.In the extracapsular rupture there were hypoechoic nodules outside the implant.Of 14 implants removed,2 were intact,3 were intracapsular and 9 were extracapsular ruptures.Conclusions Hyperfrequency ultrasonography can detect the silicone breast implants intact,intracapsular and extracapsular rupture.
