[True knots in the umbilical cord: clinical implications].

A study was performed to study the behavior of various parameters of fetoplacental functions and fetal and neonatal well-being in 51 cases with the presence of true knots in the umbilical cord at birth. No statistically significant difference was observed when these cases were compared to a control group without this pathology. The Authors underline the need for precise statistical evaluations in order to reassess the clinical significance of such umbilical alterations.
