A case of umbilical artery thrombosis in the third trimester of pregnancy

Abstract

Objective: Unknown ethiology Background: Umbilical artery thrombosis is an extremely rare complication during pregnancy. Umbilical artery thrombosis has a poor prognosis and is associated with increased rates of perinatal morbidity, including intrauterine growth restriction (IUGR), and fetal mortality. Case Report: We report a rare case of umbilical artery thrombosis, diagnosed by ultrasound, at 33 weeks gestation in a 30-year-old woman who had previously had an uneventful pregnancy. Conclusions: Umbilical artery thrombosis is a rare complication of pregnancy that is associated with high fetal mortality. Management may include planned elective delivery by cesarean section, following antenatal corticosteroid therapy for fetal lung maturation.
