Based on the information given one cannot conclude that this pregnancy is going to be nonviable. I am particulary interested in the US on 10/11 and 10/17. On 10/10 you have a 10mm by 10mm gestationsal sac which would give one an EGA of 40 days or about 5 weeks and 5 days. Based on the LMP of 8/20 the patient should be about 7weeks EGA.

The next ultrsound is 6 days later. In a normal developming pregnacy, over the course of 14 days one should expect to go from a gestational sac to seeing a yolk sac, to seeing a fetal pole (day 44) to seeing a fetal heart beat day 46 (6 weeks 4 days from LMP or 4 weeks 4 days from conception.

Most likely the perinatologist is correct. However, it would be nice to have 2 ultrasounds 2 weeks apart that do not show this nomrla progression before embarking down path of termination. Having a sac on 10/11 and 6 days later not seeing a fetal pole is not necessarily diagnositic of missed abortiion or blighted ovum. However, one should expect to see at least a 4-5mm yolk sac at the ultrasound on 10/17. (By the time one sees a 10mm gestationsal sac we should be able to see the 4mm yolk sac. By the time the gestational sac is 20mm (day 50) we should see a fetal pole)

You do not want to have a doctor who drags out needless hope for a patinet when it is obvious that there is no chance for a pregnancy. At the same time we do not want to be too quick to "right off" a potentiallynormal pregnancy. there is little risk , emotional or physical to rechecking a final trans vaginal ultrasound 7-8 days after the 10/17 ultrasound (ie this week). If there is no fetal pole then absolutely this is non viable and cytotec or out patient D&C or letting natrue take its course would be appropriate. agf

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
