K: umbilical cord has one large vein and two smaller arteries. M: wharton"s jelly (wj) observed in a 30 week fetus. One of the umbilical arteries (a) is in view vesical arteries. F: the absence of cord twisting is an indirect sign of decreased fetal movement. Umbilical coiling index (uci: the generally accepted method of assessing the degree of the umbilical cord coiling is by calculation of the. Umbilical coiling index (uci: calculated by measuring the distance between two adjacent coils of the umbilical artery from the right-outer surface of the vascular wall to its next twist. Antenatal coiling index= 1/ distance in centimeters: number of coils/ length of the cord, normal coiling index is approx 1 coil/ 5 cm of umbilical cord length. G: both normal coiling and hypocoiling of different segments of the same umbilical cord on color doppler.
