Abstract

Umbilical artery thrombosis is rare event and few prenatally diagnosed cases have been reported. Antenatal diagnosis is very critical, as it is associated with high risk of perinatal motility and morbidity such as intrauterine growth restriction and intrauterine fetal death. This study presents a rare case of intrauterine umbilical artery thrombosis, diagnosed by ultrasonography, at 32 weeks and 5 days of gestation in a 34-year-old woman who had an uneventful pregnancy. Early diagnosis with color Doppler ultrasonography is critical for pregnancy outcomes when fetal movement has diminished or intrauterine growth restriction is diagnosed, even though two umbilical artery already been confirmed on the first or the second-trimester ultrasonography scans.
