BACKGROUND
A twin gestation comprising a complete hydatidiform mole and a coexisting normal fetus is a rare and high-risk condition. Only a few such gestations have resulted in live infants. We report a case with a very large molar component presenting as a placenta previa.
CASE
A live infant was delivered by cesarean at 31 weeks of gestation. The delivery incorporated prophylactic temporary balloon occlusion of the internal iliac arteries. The patient did not develop persistent gestational trophoblastic disease.
CONCLUSION
We recommend that intra-arterial balloon catheters be considered before cesarean delivery in cases of complete hydatidiform mole with a coexisting normal fetus if the molar pregnancy presents as a previa. The size of the molar gestation is not an independent risk factor for persistent or metastatic disease.
背景
双胎妊娠中一个为完全性葡萄胎且并存一个正常胎儿是一种罕见且高危的情况。仅有少数此类妊娠分娩出活婴。我们报告一例以前置胎盘形式存在的巨大葡萄胎成分的病例。
病例
在妊娠31周时行剖宫产分娩出一名活婴。分娩过程中预防性临时球囊封堵双侧髂内动脉。该患者未发生持续性妊娠滋养细胞疾病。
结论
我们建议，如果完全性葡萄胎并存正常胎儿且葡萄胎妊娠表现为前置胎盘，在剖宫产术前应考虑使用动脉内球囊导管。葡萄胎妊娠的大小并非持续性或转移性疾病的独立危险因素。
