Harris Finberg seems to have been the first to put this hypothesis forward. As he explains it, the placenta has a propensity to grow toward areas of richer uterine perfusion and to atrophy in areas of reduced perfusion. In the areas of attrophy the amnion and chorionic surface is left as a velamentous membrane. I realize all do not adhere to this and it is controversial, and has been argued on this list (search archives). I spoke to Harris in September at the SDMS Conference and he believes trophotropism is still a viable explanation, so do I. Unfortunately, there is not much published on the subject, you can find more on vasa privia, I think. Harris did publish an extensive discussion in the Official Proceedings of the SDMS 10th Annual Conference in 1993 (Anaheim). Perhaps you could obtain a copy by calling the SDMS office: 972-239-7367.

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.
