OBJETIVE: To evaluate the performance of ultrasound clinical trial proposed by the CLAP. MATERIALS AND METHODS: A descriptive study that evaluates the likelihood of association of small for gestational age (SGA) with factore risk and ultrasound findings. RESULTS: Correlation between risk factors and the cranial circumference (CC) and abdominal (CA) lower 5th percentile dle with PEG was found. CONCLUSIONS: A significant association between risk factors and the presence of small for gestational age fetus. The high specificity and negative predictive value DC and AC make this biometrics useful for the assessment of fetal growth.

To evaluate the correlation between fetal asymmetry (DC / AC and LF / CA above the 95th percentile) and neonatal asymmetry (neonatal ponderal index (IPN) below the 10th percentile). MATERIAL AND METHOD: The monitoring data CLAP's SIP fetuses classified as asymmetric and symmetric as biometric indices. RESULTS: 1604 cases selected significant association between fetal and neonatal asymmetry was found. The LF / CA> p95 relation proved to be a good predictor of neonatal asymmetry after week 33. CONCLUSIONS: The relationship DC / AC turned out to be the best predictor of neonatal asymmetry.
