The Clinical Significance of Fetal Intra-Abdominal Umbilical Vein Varix: A Comparative Study.

ABSTRACT:

Objectives

To clarify the clinical significance and optimal management of fetal intra-abdominal umbilical vein varix (FIUVV).

Methods

A retrospective study comparing composite asphyxia-related adverse outcomes including stillbirth, cesarean delivery due to non-reassuring fetal heart rate (CD NRFHR), Apgar <7, Cord pH <7, neonatal intensive care unit admission, mechanical ventilation, seizures, asphyxia, and hypoxic ischemic encephalopathy, as well as rates of small for gestational age (SGA) and congenital anomalies, between FIUVV singletons and the general population born at a single center. A subgroup analysis included FIUVV singletons and controls delivering ≥39 weeks.

Results

Compared to controls (99,715), FIUVV subjects (142) had more congenital anomalies (15.5% v
