Giant chorangiomas are uncommon yet frequently associated with adverse pregnancy outcomes. A 37-year-old female was referred due to findings of a placental mass during a second-trimester ultrasound. A fetal survey at 26 weeks revealed a 69×97×75 mm heterogenous placental tumor with two prominent feeding vessels. Her prenatal course was complicated by worsening polyhydramnios requiring amnioreduction, gestational diabetes, and transient severe ductal arch (DA) constriction. Placental pathology confirmed the diagnosis of giant chorioangioma following delivery at 36 weeks. To our knowledge, this represents the first case of DA constriction in the setting of a giant chorangioma.
巨大绒毛膜血管瘤并不常见，但常与不良妊娠结局相关。一名37岁女性因孕中期超声检查发现胎盘肿物而前来就诊。孕26周时的胎儿检查显示有一个69×97×75毫米的异质性胎盘肿瘤，伴有两条明显的供血血管。她的产前过程因羊水过多加重需行羊水减量术、妊娠期糖尿病和短暂性严重动脉导管弓（DA）缩窄而变得复杂。胎盘病理检查在孕36周分娩后确诊为巨大绒毛膜血管瘤。据我们所知，这是巨大绒毛膜血管瘤合并DA缩窄的首例病例。
