摘　　要：目的观察孕早中期超声诊断胎盘植入的价值。方法回顾性分析经引产手术证实的10例孕早中期胎盘植入的临床资料,观察孕早中期胎盘植入的超声声像图特点。结果 10例中,9例有剖宫产手术史。术前超声诊断胎盘植入6例,主要表现为胎盘低置,胎盘与子宫肌层间界限不清,胎盘后血流信号丰富、肌层变薄。术前超声漏诊4例。引产后48h复查超声,10例均见宫内胎盘植入残留表现。结论胎盘与子宫肌层间界限不清、胎盘后血流信号丰富及肌层变薄等二维超声图像特点对诊断孕早中期胎盘植入具有高度临床价值。Objective To explore the clinical value of ultrasonography in diagnosis of placenta accreta in the first and second trimester. Methods Clinical data of 10 patients with placenta accreta in the first and second trimester confirmed by operation were retrospectively analyzed, and the ultrasonographic characteristics were observed. Results Nine patients had history of previous cesarean section. Placenta accreta was diagnosed with ultrasound before operatively abortion in 6 patients, displayed as low-lying placenta, placenta-uterine wall interface irregularity, retroplacental myometrium thinning and multiple irregular vascular spaces whthin the placenta bed. Four patients were misdiagnosised. In all the cases of placenta accreta, intrauterine residual were found 48 h after curettage. Conclusion Placenta-uterine wall interface irregularity, multiple irregular vascular spaces within the placenta bed and retroplacental myometrium thinning are valuable features in ultrasonic diagnosis of placenta accreta in the first and second trimester.
