目的
确定乳房超声检查 (US) 在评估硅胶乳房植入物破裂情况中的价值。
材料和方法
74 名出现与硅胶植入物相关的局部或全身症状的女性接受了乳房超声检查。其中 28 人接受了手术移除植入物。
结果
在移除的 57 颗植入物中，37 颗完好无损。完整植入物最可靠的标志是内部消声，尽管可以看到混响伪影和激进的褶皱。 20 个破裂的植入物中，16 个为囊内破裂，4 个为囊外破裂。最可靠的美国破裂迹象是回声水平（“阶梯”）线（20 条破裂中的 14 条）。四个囊外破裂中的两个被准确识别为植入物外的回声结节；两项是假阴性结果。超声检查发现的 3 处囊内破裂呈假阳性；六个是假阴性。破裂的总体敏感性为 70%，特异性为 92%，阳性预测值为 82%，阴性预测值为 85%。
结论
乳房超声能够描绘乳房植入物的囊内和囊外破裂。
PURPOSE
To determine the value of breast ultrasonography (US) in the assessment of silicone breast implants for rupture.
MATERIALS AND METHODS
Seventy-four women with local or systemic symptoms related to silicone implants underwent breast US. Of these, 28 underwent surgical removal of the implants.
RESULTS
Of 57 implants removed, 37 were intact. The most reliable sign of an intact implant was an anechoic interior, although reverberation artifact and radical folds could be seen. Of 20 ruptured implants, 16 were intracapsular and four were extracapsular ruptures. The most reliable US sign of rupture was echogenic, horizontal ("stepladder") lines (14 of 20 ruptures). Two of the four extracapsular ruptures were accurately identified as echogenic nodules outside the implant; two were false-negative findings. Three intracapsular ruptures identified at US were false-positive; six were false-negative. Overall sensitivity for rupture was 70%, specificity was 92%, positive predictive value was 82%, and negative predictive value was 85%.
CONCLUSION
Breast US is capable of depicting intracapsular and extracapsular rupture of breast implants.
