目的探讨孕中期超声诊断帆状胎盘的价值。方法选自我院于2014年6月~2016年12月期间20 371例孕妇分娩,应用美国GEE8彩色多普勒B超诊断仪,对孕产妇常规检查,取平卧位,根据产科检查依次检测双顶径、头围、腹围和股骨长,进行常规超声测量,同时检查羊水和胎盘。结果本组20 371例孕妇分娩中,帆状胎盘孕妇27例、非帆状胎盘孕妇20 344例。根据是否为帆状胎盘分为帆状胎盘组和非帆状胎盘组;两组平均年龄、平均孕周及产妇类型比较无统计学差异(P>0.05);帆状胎盘组多肽和前置胎盘发生率明显高于非帆状胎盘组,均有统计学差异(P<0.05);帆状胎盘组宫内死胎和围生儿死亡率高于非帆状胎盘组,均有统计学差异(P<0.05);27例患者超声诊断漏诊2例、误诊1例、符合24例,诊断符合率为88.89%。结论孕中期采用彩色多普勒B超诊断是帆状胎盘诊断的有效方法,具有简便、准确率高、安全特点,可为临床诊断治疗提供可靠参考依据。
Objective To explore the value of mid-second trimester ultrasound diagnosis of sail placenta. Methods From July 2014 to December 2016, 20 371 pregnant women were delivered in our hospital from January 2014 to December 2016. The pregnant women were routinely examined by GEE8 B ultrasound diagnostic apparatus. The pregnant women were tested for supine position, Top diameter, head circumference, abdominal circumference and femur length, conventional ultrasound measurements, while checking amniotic fluid and placenta. Results In the group of 20 371 pregnant women, there were 27 pregnant women with sail-like placenta and 20 344 pregnant women with non-sail placenta. According to whether the sail-like placenta was divided into sailing placenta group and non-sailing placenta group; the average age of the two groups, the average gestational age and maternal genotypes were no significant difference (P> 0.05); sagittal placental polypeptide and placenta previa (P <0.05). The mortality of stillbirth and perinatal fetus in sail-like placenta group was significantly higher than that in non-sail-like placenta group (P <0.05), and the difference was statistically significant (P <0.05). Twenty-seven patients missed diagnosis in 2 cases and misdiagnosed in 24 cases, the diagnostic coincidence rate was 88.89%. Conclusion It is an effective method to diagnose the placenta with color Doppler ultrasonography in the second trimester. It is simple, accurate and safe, which can provide a reliable reference for clinical diagnosis and treatment.
