Placenta previa in association with placenta accreta has been recorded on average in 1 in 500 pregnancies; its association with placenta percreta is a much rarer condition. We report an unusual case of placenta previa which presented as a severe form of occult parasitic infiltration, invading the internal iliac vessels. This was followed by life-threatening complications, despite preventative measures. Use of a prediction index to suspect placenta previa is mentioned.
前置胎盘合并胎盘植入的发生率平均为每500例妊娠中有1例；其与穿透性胎盘植入的关联则更为罕见。我们报告了一例罕见的前置胎盘病例，该病例表现为一种严重的隐匿性寄生虫浸润形式，侵入了髂内血管。尽管采取了预防措施，但仍出现了危及生命的并发症。文中提到了使用预测指标来怀疑前置胎盘。
