目的探讨产前超声检查在胎盘植入的产前诊断及预测预后方面的价值。方法对78例在产科住院分娩或行剖宫产、且产后由临床诊断和病理证实为胎盘植入的产前超声检查声像图进行回顾性分析,研究胎盘的声像图特征,由胎盘的位置比较其产前检出率。结果前置胎盘组的检出率高于对照组,胎盘前壁组的检出率高于对照组,差异均有统计学意义。结论产前超声检查检出前置胎盘及胎盘位于子宫前壁时有利于胎盘植入的产前诊断。结合其他超声声像图特征,并分析胎盘植入的临床危险因素能有效预测其临床预后,降低并发症的发生,具有重要的临床意义。
Objective To investigate the value of prenatal ultrasound in prenatal diagnosis and prognosis of placenta accreta. Methods A retrospective analysis of 78 cases of childbirth or cesarean delivery in obstetrics and gynecology and postnatal diagnosis of placenta accreta was performed for the diagnosis of placenta accreta. Location compared to their prenatal detection rate. Results The detection rate of placenta previa group was higher than that of control group, and the detection rate of anterior placental wall group was higher than that of control group, the differences were statistically significant. Conclusions Prenatal ultrasound examination can detect prenatal placenta and placenta located in the anterior wall of the uterus in favor of prenatal diagnosis of placenta accreta. Combined with other ultrasonographic features and analysis of placenta accreta risk factors can effectively predict the clinical prognosis and reduce the incidence of complications, has important clinical significance.
