Sorry to hear about your sister. I am a Canadian citizen and was recently back there for a visit. Because it had been so long since I was home, my medicare was expired and I was on travel insurance, I found out I was pregnant over there and had such bad pain I thought I was having an ectopic, my insurance covered the ER visit and ultrasound and would have covered the surgery to remove it had it come to that. I think they cover any emergency situation as long as it was not a pre-exisiting condition, so if your sister got pregnant after cover than she may be covered for it, especially if she can get the doctor to say it is an emergency situation. I hope everything works for the best. It is so stressful being away from home and not having your usual medical care available.
It sounds as if the procedure to remove the embedded IUD would be fairly dangerous for the pregnancy - i.e. just getting it out would disrupt the tissues of the placenta etc. The cervical stitch is not an option. Miscarriage with an IUD is usually caused by disruption of the placenta/rupture of the sack during removal or septic infection when it has been left in place, not a weak cervix. A cervical stitch holding a septic pregnancy could potentially cause death, because it's just preventing the body from ridding itself of the infection. That's very rare though, because if the pregnancy becomes septic they pump you full of anti-B's and hasten the loss to protect your health (there is no way to save the baby in that case).
Lesty i have read that embedded IUD's give far better outcomes but i can't find a study. Apparently the fact that it has become buried in the uterine wall means the body can prevent infection more effectively. I'm sure she is under considerable medical pressure to terminate. I really feel for her, so far from home, I really hope she's ok
