DuBose: "Re: two yolk sacs,one embryo" I would like very much to see a true double bleb sonogram. Thanks, Terry ultrasound@obgyn.net writes: > Dear Colleagues, >I should have in my zambeel an image of a so-called double bleb sign (and I'll search for it and send it if you like),but I clearly remember that of the two partially fused rings,one had a thicker wall (and it was the yolk sac:the reason being the vitelline vascular net on its surface,as Dr.Moroder said),the other-the thinner-was the amnion of an aborted embryo-early demise with subsequent reabsorption-as usually happens with chromosomal anomalies-this is the in-between picture that ends up with >a blighted ovum-and the mean outer diameter of these double-blebs is -almost always-bigger than usual (usual diameter of the y.s. being 5mm more or less).So,at the very beginning (2-3 mm CRL),the amnion wraps around the developing embryo and it does not show on the ultrasound-and the embryo is stuck to the secondary y.s. wall-like any caption from a textbook of embryology can show.(again,in accordance with Dr.Moroder). >In Dr. Libardi's case I stated we're dealing with a monochorionic diamniotic pregnancy-therefore there are two separate yolk sacs,no double bleb sign,maybe a slight disproportion between the two embryos-although I think that a slight difference in the angles of the scan could have shown both embryos. >In the end,the follow up is everything >Andrea Corda MD Peace, Terry J.

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.
