The reason for sudden antenatal death syndrome (SADS) are not well established. Umbilical cord accidents (UCA) are one of the causes of SADS. In UCA, umbilical venous and/or umbilical arterial flow is compromised and leads to intrapartum death of the foetus. Presenting here is a case report of cord constriction leading to late second trimester intrauterine foetal death.
