Hysterectomy is the standard procedure, but obviously isn't performed if the patient doesn't want it (which in this case is idiotic, but removing organs without consent is never allowed). The reason she flew abroad was not that her doctors would force her to undergo hysterectomy (which would be against medical ethics), but simply that they had less experience in placenta accreta surgery. Many patients that suffer this complication aren't in such a ridiculous situation, and keeping their womb is an interesting option for them, it is routinely offered in mild cases. Since placenta accreta is very common in China, there are many doctors there who are specialized in it, that's all.
