Chorioangiomas are benign placental tumours derived from fetal vessels, that occur with a frequency of approximately 1%. Often they are associated with hydramnios and intra-uterine fetal death. Based on a case of multiple chorioangiomas with a fatal course for the baby, aspects of the pathogenesis of hydramnios are discussed. Future development in ultrasounc technology may facilitate antenatal diagnosis.
绒毛膜血管瘤是源自胎儿血管的良性胎盘肿瘤,其发生率约为1%。它们常与羊水过多和宫内胎儿死亡相关。基于一例导致婴儿死亡的多发性绒毛膜血管瘤病例,本文讨论了羊水过多的发病机制。超声技术的未来发展可能会促进产前诊断。
