Umbilical cord noise

An umbilical cord murmur is an acoustic phenomenon observed in certain pathologies of the placenta or uteroplacental arteries in pregnant women. This phenomenon occurs as a result of the presence of a murmur that can be heard during ultrasound and can be interpreted as increased pulsation of the maternal umbilical arteries. This noise can be caused by various reasons, including vasodilation, plaque formation, vasospasm, etc.

Noises can appear both during pregnancy and after childbirth. They usually occur in the first or second trimester of pregnancy. In women with chronic chorioamnionitis, gestational diabetes or hypertension, or a history of other chronic diseases, cord noises may be a marker of impaired placental blood flow. Loud noise can be a sign of early pregnancy, which indicates a good chance of successful conception. However, loud noise is a sign of possible problems with fetal development.
