Re: Measuring AFI in a Diamniotic Twin pregnancy

I advocate the "subjective evaluation" by an experienced eye. Keeping in mind that the pressures in both sacs should be equal and the membrane will be flaccid. If there is higher pressure on one side the sac should bulge toward the other side. I know of no really valid way of measuring the fluid in multiple sacs.

This has been discussed here from time to time and if you go to the Web archive of the discussions you can do a search for those comments.

Had a recent case of a diamniotic twin pregnancy (28 weeks and 31 weeks AOG) which on eyeballing alone both sacs appeared to have polyhydramnios. OB-GYN doctor was insisting to measure each individual amniotic sac.

There appears to be twin-to-twin transfusion syndrome and/or hydrops fetalis in this pregnancy.

Thank you.

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.
