Chorioangiomas are usually small and found by careful sectioning of the placenta. In recent years ultrasonography has been used in antenatal diagnosis. Multiple and large tumors (greater than 5 cm) are associated with increases in fetal morbidity and mortality. We treated a woman who had severe polyhydramnios and a large chorioangioma with vascular channels in the tumor confirmed by Doppler studies. Daily fetal breathing was used to monitor fetal well-being.
绒毛膜血管瘤通常较小，通过仔细检查胎盘才能发现。近年来，超声检查已用于产前诊断。多个大肿瘤（大于5厘米）与胎儿发病率和死亡率增加有关。我们治疗了一名患有严重羊水过多和大绒毛膜血管瘤的妇女，多普勒研究证实肿瘤内有血管通道。每日进行胎儿呼吸监测以评估胎儿健康状况。
