“…An abnormally short or long cord is the second prevalent disorder. 6 In fact, long cords increase the risk of cord entanglements, emergency deliveries, fatal placental vasculopathies, intrauterine fetal death, and neurological disorders, whereas short cords account for complications such as fetal malformations, fetal distress, and placental abruption. 5 Other abnormalities such as a single-artery cord, cord cysts, and true and false cord knots are less common.…”

“…The most common disorder that occurs for the umbilical cord is its prolapse, which can lead to stillbirth. An abnormally short or long cord is the second prevalent disorder 6 . In fact, long cords increase the risk of cord entanglements, emergency deliveries, fatal placental vasculopathies, intrauterine fetal death, and neurological disorders, whereas short cords account for complications such as fetal malformations, fetal distress, and placental abruption 5 .…”

“…Hence, umbilical cord status is crucial to fetal well‐being, 1 and anomalies affecting the umbilical cord can increase fetal stress risk and, in severe cases, lead to fetal demise. Among observed umbilical cord abnormalities are umbilical cord knots (UCK).…”

“…The normal umbilical cord contains two arteries and one vein covered by Wharton jelly, and it is commonly described as the “lifeline.” 1 The health and safety of this “lifeline” is crucial to maintain proper functions, which include delivery of nutrients and extrusion of fetal waste 1 . Some of the factors affecting the health and status of the umbilical cord include the length and coiling 2–5 .…”

Knot(s) of the umbilical cord have received emphasis because the clinical assessments and sonographic literature show a crucial role in fetal outcomes. The true umbilical cord knot could be a knot in a singleton pregnancy or an entanglement of two umbilical cords in monoamniotic twins. Clinical manifestations are almost silent, which can raise clinical challenges. They worsen outcomes, and the pathology can be easily missed during prenatal visits because ultrasonographers do not pay attention to the cord during an obstetric ultrasound scan. However, most medical centers now have ultrasound machines that improve fetal assessment. The umbilical cord should be routinely evaluated during a fetal assessment, and suspicion of an umbilical cord knot can be more frequently diagnosed and is detected only incidentally. Clinical outcome is usually good but depends on the knot's characteristics and if it is tight or loose. In this review, we discuss pathophysiology, the theories on formation, the main risk factors, ultrasound signs and findings, different opinions in the management, and features of pregnancy outcomes feature.

“…During prenatal development, the umbilical cord connects the placenta and fetus and is a physiological and genetic part of the fetus. The single umbilical vein carries oxygenated blood to the fetus, while the two umbilical arteries spiral around the umbilical vein within the cord to return de-oxygenated blood back to the placenta (Hubbard and Stanford, 2017). Amniotic fluid generated from maternal plasma in the amniotic sac can pass through fetal membranes by osmotic and hydrostatic forces, and protects the developing fetus, allowing for easier fetal movement, and promoting skeletal and muscular development (Notice, 1981;Underwood et al, 2005).…”
