目的：分析胎盘植入的超声影像特点，探讨产前超声检查对胎盘植入的诊断价值。方法选择我院在2011年12月～2014年8月收治的51例胎盘植入患者作为研究对象，回顾性分析产前超声检查的检出情况，并总结超声图像特点。结果产前超声检查检出率为37.25%，检出患者的超声图像特点为胎盘内漩涡形成、未见胎盘后间隙消失、子宫肌层局部菲薄以及胎盘异常增厚。结论产前超声检查有利于胎盘植入的早期诊断，结合超声声像图特征，对胎盘植入的产前诊断具有重要意义。%Objective To analyze the characteristics of ultrasonography for placenta increta, explore the value of prenatal ultrasonography in diagnosis of placenta increta. Methods From December 2011 to August 2014, 51 cases with placenta increta in my hospital were selected as the research object, the ultrasonic image data were analyzed retrospectively, and summarized the characteristics of ultrasound image. Results The rate of prenatal ultrasound detection for placenta increta was 37.25%;The ultrasonic image characteristics for placenta increta was the vortex formation in the placenta, no disappearing placental post-clearance, local thinning muscular layer of uterin, and abnormal thickening placenta. Conclusion Prenatal ultrasound is beneficial to early diagnosis of placenta increta, and ultrasonographic features has important signiifcance in prenatal diagnosis of placenta increta.
