Abstract

Background: Arteriovenous malformation of umbilical cord is an extremely rare congenital malformation. Causes of this condition are unknown. AVM of umbilical cord can cause significant complications in the developing fetus.

Methods: We report our management of the case with accurate ultrasound study that could improve and facilitate the approach to this pathology due to the lack of literature and with an overview of the available literature.

Results: There are only two cases of umbilical AVM diagnosed in the prenatal period with associated pathology. The mainstay of prenatal detection is the accurate study of umbilical cord also even if it is not requested from the actual guide lines in a way to improve the perinatal morbidity and mortality.
