Abstract

Umbilical cord rupture (UCR) in utero is a very rare and critical emergency that can cause fetal death within minutes. A 38-year-old nulliparous woman was admitted at 39 weeks in labour. Sudden watery vaginal discharge and bleeding with a rapid drop in the fetal heart rate to 60 beats/min necessitated an emergency caesarean section. A male infant weighing 2632 g was delivered 21 min after the onset of bradycardia; Apgar scores were 0 and 1 at 1 and 5 min, respectively. He was extremely pale; the umbilical arterial blood pH was 6.89 and haemoglobin was 9.0 g/dL. The umbilical cord had a velamentous insertion and was lacerated, with haemorrhage in the outer layer of an umbilical artery close to the placental end. The presentation was typical of UCR: vaginal bleeding following the rupture of membranes. Prompt diagnosis of UCR and termination of pregnancy are essential for fetal survival.
