[Detection of intrauterine fetal growth retardation using ultrasound fetometry].

Based on ultrasonic foetometry at an interval of 0-59 days before delivery the authors assessed in 93 women with risk pregnancies hospitalized during the 31st-43rd week of gestation the index of the femur length/abdominal circumference independent on gestation age, and they estimated the foetal weight by means of three logarithmic formulae comprising the biparietal diameter, femur/length and abdominal circumference. For detection of foetal hypotrophy, the estimated weight of the foetus in particular according to the formula of Hadlock et al. (sensitivity 58.3%, specificity 94.22%) was significantly more accurate than the index of femur length/abdominal circumference > or = 23.0 (sensitivity 45.8%, specificity 91.3%).
