UMBILICAL VENOUS PULSATION AND REGIONAL CIRCULATORY DISTURBANCE

The umbilical cord conditions at the point where regional umbilical ve nous pulsation occurred were examined in 15 patients between the 28th and 40th gestational week, The patients delivered appropriate-for-date infants without anomalies, Regional venous pulsation was observed in cases of large-angle cord winding (especially more than 60 degrees). I t was also observed where the umbilical cord was compressed by the fet us, uterine wall or placenta, even if the umbilical cord was straight, From these findings, we concluded that regional umbilical venous puls ation is the result of regional circulatory disturbance of the umbilic al cord.
