Discover how this unique phenomenon can transform anxiety into purpose, nurture resilience, and foster a profound Routine surveillance of the umbilical cord for knots may not be justifiable because it is time consuming and of uncertain sensitivity or benefit. We describe a case of acute intrapartum fetal hypoxia, with extraction of the fetus by a c‐section, and the isolated finding of a true umbilical cord knot. True umbilical cord knot is a relatively common complication that occurs in 0. These knots are dangerous because they can compress the blood vessels in the umbilical cord and deprive the baby of oxygen. Factors, yet unknown, contribute to antenatal tightening of a true knot.
