Varix of the fetal intra-abdominal umbilical vein: prenatal sonographic diagnosis and suggested in utero management

Varix of the fetal intra-abdominal umbilical vein (FIUV) is a rare entity. We describe an ultrasound diagnosis of this condition together with a revie w of the literature relating to its prognosis and management. Our conclusio n is that close fetal monitoring should be performed and delivery should be induced when lung maturity has been accomplished or any fetal distress is apparent.
