Prenatal diagnosis of umbilicoportosystemic shunts: report of 11 cases and review of the literature.
OBJECTIVE
The objective of our study was to classify, understand, and illustrate abnormalities of the embryologic development of the umbilical vein and the portal system resulting in umbilicoportosystemic shunts. According to our data and a review of the literature, we propose an anatomic, biometric, and hemodynamic assessment of umbilicoportosystemic shunts.


CONCLUSIONS
Umbilicoportosystemic shunts encompass different congenital vascular abnormalities that should be recognized because they may interfere with fetal growth and circulation.
