umbilical vein vs umbilical artery thrombusFrom: Barbara A. Bennett (bbennett@stny.lrun.com)Mon Aug 24 20:50:20 1998
I was called to the Birthing Center today for possible fetal demise, which was verified by m-mode. It was a very quick scan as patient was hysterical, but happened to see umbilical cord with echogenic material within in it. My first thought was umbilical vein thrombosis, but on a transverse view of the cord, two structures appeared to be echogenic, and only one sonolucent. Is it possible for both umbilical arteries to thrombose? How long after a demise would that take place? I have not been able to find anything on UA thrombosis. There is a short reference and one image in Callen second edition for UV thrombosis. I just attempted a medline search, but didn't get much info and got a few ERROR messages. NOt sure if that was me or my Mac :( Also, patient appeared to have a retroplacental abruption. Placenta was very thick, and non-homogeneous. But, patient denies any pain or bleeding. We have no previous studies. Any ideas or references? Thanks, Barbara, RDMS

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.
