Umbilical Cord Problem

Brief summary

The umbilical cord plays an essential role in intrauterine life. It is the pathway between mother, placenta and fetus during pregnancy and delivery. Complete cord occlusion often leads to fetal demise, while intermittent occlusion has been associated with intrauterine brain damage. Compression and vasospasm in utero are important factors in fetal distress. Nuchal Umbilical Cord can be diagnosed antepartum using ultrasound, but the complications are unpredictable and unpreventable

Interventions

DIAGNOSTIC_TESTultrasonography

Ultrasound evaluation will be done with transducer abdominal probe. The amount of amniotic fluid and umbilical cord sections will be determined by evaluating the images obtained from the sagittal plane in the ultrasound evaluations in the 4 abdominal quadrants. When the anatomical structure of the umbilical cord is considered, it is folded in amniotic fluid. The folds appear as umbilical cord rings, side-by-side at the sagittal sections. Scoring of umbilical cord length index * 1 point will be given for each quadrant where the umbilical cord was observed. * 0.5 point will be given for each umbilical cord ring in one quadrant. Every quadrant will be evaluated in this manner, and the total score will be calculated.
