摘　　要：目的探讨超声诊断为胎盘绒毛膜血管瘤的临床特征和妊娠结局。方法选取超声诊断为胎盘绒毛膜血管瘤的孕妇23例为病例组(其中,最大直径≥4 cm为巨大组、最大直径<4 cm为普通组),以及同期正常孕妇60例为对照组,分析其临床特征和妊娠结局的差异。结果与对照组相比,病例组的自发性阴道分娩率较低、辅助性阴道分娩率较高(P<0.05)。胎盘绒毛膜血管瘤的超声表现:胎盘实质区内及胎盘边缘可见单发或多发中低回声肿物,常靠近脐带插入部,部分内可见血流信号。与普通组相比,巨大组的中孕期检出率高达100%、并发症高(P<0.05)。与普通组、对照组相比,巨大组的自发性阴道分娩率较低、辅助性阴道分娩率较高、新生儿具有早产率高、出生体重低、阿普加评分低、以及NICU入院率及住院天数显著增加(P<0.05)。结论产前超声诊断为巨大胎盘绒毛膜血管瘤对于不良妊娠结局的预测具有重要意义。Objective To investigate the clinical features and pregnancy outcomes of placental chorioangioma diagnosed by ultrasound.Methods A total of 23 pregnant women with placental chorioangioma diagnosed by ultrasound were selected as the case group.Among them,the women with the largest diameter of the tumor≥4 cm were defined as the giant group,and the women with the largest diameter of the tumor<4 cm were defined as the general group.Another 60 normal pregnant women were selected as the control group.The differences in clinical features and pregnancy outcomes were analyzed.Results Compared with the control group,the case group had a lower spontaneous vaginal delivery rate and a higher assisted vaginal delivery rate(P<0.05).The ultrasonic manifestations of placental chorioangioma included single or multiple medium to low echo masses that could be seen in the placental parenchymal area and at the edge of the placenta,which were often close to the insertion of the umbilical cord,with blood flow signals that could be seen in some areas.Compared with the general group,the detection rate during mid pregnancy in the giant group was as high as 100%,with high complications(P<0.05).Compared with the general group and control group,the giant group had a lower spontaneous vaginal delivery rate,higher assisted vaginal delivery rate,higher preterm birth rate,lower birth weight,lower Apgar score,and a significant increase in NICU admission rate and hospital stay(P<0.05).Conclusion Prenatal ultrasound diagnosis of giant placental chorioangioma was of great significance in predicting adverse pregnancy outcomes.
