We performed an 18-year retrospective chart review of the medical records of mothers and infants with ELUCs (926 cases) and normal-length UCs (200 cases) and recorded maternal factors, fetal factors, and neonatal outcomes. Corresponding placental pathologic reports and slides were reviewed. Statistical analysis comparing the two groups included univariate and multivariate analyses. <\/jats:p><jats:p> ELUCs were significantly associated with certain maternal factors (systemic diseases, delivery complications, increased maternal age), fetal factors (non-reassuring fetal status, respiratory distress, vertex presentation, cord entanglement, fetal anomalies, male sex, increased birth weight), gross placental features (increased placental weight, right-twisted cords, markedly twisted cords, true knots, congestion), and microscopic placental features (nucleated red blood cells, chorangiosis, vascular thrombi, vascular cushions, meconium, increased syncytial knots, single umbilical artery). Some of these histopathologic features have previously been associated with fetal hypoxia and\/or altered blood flow in the placenta. Infants with ELUCs were found to be at a significantly increased risk of brain imaging abnormalities and\/or abnormal neurological follow-up. In addition, mothers with a history of an ELUC are at increased risk of a second long cord.
