摘　　要：目的探讨完全型轮状胎盘产前超声征象、临床特点及对妊娠结局的影响。方法回顾性研究单胎活产的完全型轮状胎盘病例的产前超声表现及临床资料,对比同时期非轮状胎盘的179213例病例孕妇围产期并发症及胎儿预后等。结果病例组共44例,其中小于胎龄儿(SGA)、胎盘早剥及早产发生率均比对照组增高,差异有统计学意义(P<0.05)。22例产前诊断的完全型轮状胎盘病例中,11例胎盘增厚,16例胎盘边缘隆起,5例出现胎盘架;回顾漏诊病例的超声图像,4例胎盘增厚。16例完全型轮状胎盘进行病理检查,其中14例符合母体血管灌注不良的病理改变。结论完全型轮状胎盘增加SGA、胎盘早剥及早产风险,产前超声筛查具有重要意义。Objective To investigate the prenatal ultrasound signs and clinical characteristics of complete circum-vallate placenta and its impact on pregnancy outcomes.Methods A retrospective study was performed on the prenatal ultrasound manifestations and clinical data of complete circumvallate placenta cases of singleton live birth,and the per-inatal fetal prognosis of 179213 cases without circumvallate placenta in the same period was included as the control.Results A total of 44 cases were enrolled in the case group,and the incidences of small for gestational age(SGA),placental abruption,and preterm birth were higher than those in the group without circumvallate placenta,and the differences were statistically significant(P<0.05).Among the 22 cases of complete circumvallate placenta diagnosed prenatally,11 cases had thick placenta,16 had placental margin bulging,and 5 had placental shelf.A review of the ultrasound images of missed cases showed placental thickening in 4 cases.Sixteen cases of complete circumvallate pla-centa underwent pathological examination,and 14 of them were consistent with the pathological changes of maternal vascular malperfusion.Conclusions Complete circumvallate placenta increases the risk of SGA,placental abruption and preterm birth,and prenatal ultrasound screening is of great clinical significance.
