目的 探讨胎盘绒毛膜血管瘤的超声图像特征、临床意义及处理方法.方法 对19例胎盘绒毛膜血管瘤患者的超声资料及临床资料作回顾性分析.结果 19例经产后病理确诊为胎盘绒毛膜血管瘤的病例均在孕期超声准确诊断,孤立血管瘤表现为12例(63.2%),合并胎儿心脏增大者1例(5.3%),合并羊水过多4例(21.1%),其中2例(10.5%)同时合并胎儿生长受限,羊水过少2例(10.5%).结论 小的绒毛膜血管瘤一般影响不大,胎儿预后良好,大型血管瘤往往引起胎儿早产、生长受限、羊水过多等并发症,彩色多普勒超声可以辅助诊断胎盘绒毛膜血管瘤.%Objective To describe the ultrasonic characteristics of placental chorioangioma and evaluate the fetuses 'prognosis. Methods Clinical and ultrasonic data of 19 cases with placental chorioangioma were studied retrospectively . Results Nineteen cases confirmed by pathological examination were diagnosed during pregnancy period . There were 12(63.2% ) cases with isolated chorioangioma , 1 (5. 3% ) with fetal cardiac enlargement , 4 (21. 1% ) with polyhydramnios including 2 ( 10. 5% ) with fetal growth restriction, and 2 ( 10. 5% ) with oligohydramnios. Conclusion The majority of pregnancies with mild chorioangiomas are asymptomatic , and the prognosis is good. Pregnancies with giant chorioangiomas are usually associated with maternal and fetal complications , such as premature birth , growth restriction, polyhydramnios , and so on. Color Doppler ultrasonography is effective in assistant diagnosis of placental chorioangioma.
