The coiling of the umbilical vessels develops as early as 28 days after conception and is present in about 95% of fetuses by 9 weeks of conception. The helices may be seen by ultra sonob graphic examination as early as during the first trimester of pregnancy.
The study was planned in the Department of Gynecology and Department of Radiology in Katihar medical college and hospital. The data from the 50 patients were collected and presented as below. UCI was calculated by dividing total number of coils by the total length of the cord in centimeters.
The short umbilical coiling index is an marker of adverse perinatal outcome. It is related with low apgar score, meconium staining, and pregnancy induced hypertension. Consequently, antenatal detection of coiling index can identify fetus at risk.
