目的探讨高、低频超声联合应用检查对中晚孕期前壁胎盘植入的诊断价值。方法回顾性分析南充市中心医院2009~2013年经手术病理证实的41例前壁胎盘植入的产妇的高、低频联合超声图像和临床资料,总结分析其声像图特征,提高临床对胎盘植入诊断的准确性。结果在41例胎盘植入病例中,术后及病理证实:胎盘粘连(浅层植入)15例,深层胎盘植入23例,穿透性植入3例;高、低频超声联合诊断31例,诊断符合率为75.61%,误诊3例,漏诊7例。结论高、低频超声联合检查,弥补了常规腹部低频探头的近场观察盲区的不足,可提高前壁胎盘植入的检出率,具有较高的临床应用价值。
Objective To investigate the diagnostic value of high and low frequency ultrasound combined with the application of placenta accreta in anterior wall of middle and late pregnancy. Methods The high and low frequency ultrasound images and clinical data of 41 cases of anterior placenta accretated by the anterior wall placenta confirmed by surgical pathology from 2009 to 2013 in Central Hospital of Nanchong were retrospectively analyzed. The characteristics of sonography were analyzed and analyzed. Diagnostic accuracy. Results In 41 cases of placenta accreta, postoperative and pathological findings included 15 cases of placenta accreta (superficial implants), 23 cases of deep placenta accreta and 3 cases of penetrating implants. 31 cases were diagnosed by high and low frequency ultrasound , The diagnostic coincidence rate was 75.61%, misdiagnosis in 3 cases, missed diagnosis in 7 cases. Conclusions High and low frequency ultrasound combined examination can make up for the shortcomings of near-field blind spot in conventional abdominal low-frequency probe, which can improve the detection rate of placenta accreta in anterior wall and has high clinical value.
