Resumo: | Objectives: To predict the birth weight of twin pregnancies using models that include fraction limb volume using three-dimensional (3D) ultrasonography. Methods: This was a prospective cross-sectional study with 51 pregnant women whose deliveries were performed within a range of up to 05 days after the ultrasonographic evaluation. The fetus weights were estimated from the Hadlock formula 4 and the models that used fraction limb volume. We still created a new model that associated fraction arm volume (AVOL) and thigh (TVol) to estimate birth weight. Results: Considering the percentage change in relation to birth weight, we observed that for the dichorionic pregnancies, the Hadlock model had a mean of 8.45% variation, while the TVol model showed a 6.60% variation. For the monochorionic pregnancies, the Hadlock model had a variation of 5.65%, while the TVol model showed a variation of 6.65%. These differences were not statistically significant (p = 0.363 and 0.678 for dichorionic and monochorionic, respectively). Conclusion: The estimate of birth weight obtained by the formulas that included the fraction limbs presented excellent agreement with the birth weight being alternative to the model proposed by Hadlock. |
