A prospective cross‐sectional study was developed to determine the correlation between the umbilical cord cross‐sectional (UCCSA) and fetal anthropometric parameters during normal pregnancies (patients with known dates of LMP and an ultrasound examination before the 20th week, without any pathologic condition). The measurements of the umbilical cord cross‐sectional area were obtained in a plane adjacent to the insertion of the cord in the abdomen, as proposed by Raio et al. , 1999, and compared to the biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur length (FL) by the non‐parametric correlation of Spearman. The inclusion criteria were: (1) singleton pregnancy; (2) gestational week >20 weeks; (3) intact membranes; (4) normal umbilical Doppler flow velocimetry. The exclusion criteria, in the presence of any of those were: (1) congenital and/or chromosomal abnormalities; (2) pregnancy complications (any type); (3) inadequate size for gestational agent the time the ultrasound examination was performed, i.e. the weight below the 10th or above the 90th percentile; (4) abnormal AFI. The patients were examined and included only once. The statistical analysis was performed by the program called Statistical Package for Social Sciences (SPSS) and we used a Toshiba 140 with a transabdominal transducer of 3.5 MHz. Our results showed a strong correlation (Spearman rank = 0.610, significant at the level of P < 0.01) between the UCCSA and the estimated fetal weight by ultrasound examination and also with the fetal anthropometric parameters (UCCSA × BPD = 0.622; UCCSA × HC = 0.617; UCCSA × AC = 0.625; UCCSA × FL = 0.604, all of them significant at the level of P < 0.01). We concluded that the UCCSA is a parameter that can be included at the routine of obstetrical ultrasound examinations.
