Julia, your image came through very nicely. Below you will find the abstract of a recent article that mentions this condition. If you can not find more on it, let me know.

In the mean time, with your permission, I would like to put your image up on the Ultrasound section of the OBGYN.net (http://www) as an informal case study. That way you may get more feed-back from others who have already been there. Please respond if I may post your image. I will notify you of the URL so you can find it once it is up. Thanks. Terry J. DuBose, M.S., RDMS

I've attached an image of 28wk fetus, transverse view of abd with dilated umb vein. there have been two OB patients of recent with same problem. No other abnormalities found. The physician indicated to the patient that we would follow it but not to worry. It's not a problem. Can anyone guide me where I might find articles on this subject? I have been searching in the textbooks but none found. Julia Moyers, RDMS

Authors Moore L. Toi A. Chitayat D. Institution Department of Radiology, The Toronto Hospitals--General Division, Ontario, Canada. Title Abnormalities of the intra-abdominal fetal umbilical vein: reports of four cases and a review of the literature. [Review] [16 refs] Source Ultrasound in Obstetrics & Gynecology. 7(1):21-5, 1996 Jan.

Abstract Anomalies of the fetal umbilical vessels are rare, excepting single umbilical arteries which occur in 0.2-1.0% of pregnancies. Abnormalities of the intra-abdominal umbilical vein may be categorized into three main groups: (1) the ductus venosus is patient but the right umbilical vein persists; (2) the ductus venosus is not patent, and there is extrahepatic continuation of the umbilical vein; and (3) the umbilical vein takes a normal course but is abnormally dilated. We describe cases of each of these types of anomaly, including the first report of prenatal diagnosis of insertion of the umbilical vein into the iliac vein, and review the literature on this subject.

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.
