摘要目的:分析超声检查在胎盘血管瘤产前监测、治疗和预后中的价值。方法:回顾分析本院15例胎盘血管瘤超声影像特征、病理结果、胎儿及其附属物并发症和妊娠结局。结果:本研究15例，活产13例，引产2例，产前超声和产后病理均诊断瘤体直径>5 cm的胎盘血管瘤13例，出现胎儿及其附属物并发症8例61.54%（8/13）；瘤体直径<5 cm的2例，未出现胎儿及其附属物并发症。瘤体紧邻脐带胎盘入口处9例，出现胎儿及其附属物并发症7例77.78%（7/9），其中出现胎儿贫血5例，胎儿心力衰竭4例（予宫内治疗3例），羊水过多3例，胎儿生长发育迟缓2例，胎儿全身水肿、宫内窘迫、羊水过少各1例。结论:利用超声监测妊娠期胎盘血管瘤瘤体变化、胎儿及其附属物并发症情况，可以为产前临床干预及预后判断提供有力证据。

abstractsObjective:To evaluate the value of ultrasonographic diagnosis in prenatal monitoring, treatment, and prognosis of patients with placental chorioangioma.Methods:The ultrasonographic features, pathological results, fetal complications, and pregnancy outcomes of 15 cases of placental chorioangioma were retrospectively analyzed.Results:Among the 15 cases, 13 had live birth and 2 got induction; 13 were confirmed with >5 cm chorioangiomas by prenatal ultrasound and postpartum pathology, and 8 cases (61.54%) developed complications; 2 cases had <5 cm chorioangiomas, with no complications. 9 cases had chorioangiomas on the umbilical cord near placenta, 7 cases had complications in the fetuses and appendants; 5 fetuses had anemia, 4 heart failure, 2 intrauterine growth retardation, 1 hydrops, and 1 intrauterine distress; 3 got polyhydramnios and 1 oligohydramnios.Conclusion:The variations of placental chorioangioma, fetal complications, and amniotic fluid should be monitored by ultrasound. Monitoring results can provide evidences for prenatal clinical intervention and prognosis evaluation.
