Purpose: to evaluate the prognosis of fetal omphalocele after prenatal diagnosis. Methods: fifty-one cases with prenatal diagnosis of fetal omphalocele were divided into three groups: group 1, isolated omphalocele; group 2, omphalocele associated with structural abnormalities and normal karyotype; group 3, omphalocele with abnormal karyotype. The data were analyzed for overall survival rate and postsurgery survival, considering associated malformations, gestational age at delivery, birth weight and size of omphalocele. Results: group 1 corresponded to 21% (n = 11), group 2, 55% (n = 28) and group 3,24% (n = 12). All of Group 3 died, and trisomy 18 was the most frequent chromosomal abnormality. The survival rate was 80% for group 1 and 25% for group 2. Sixteen cases underwent surgery (10 isolated and 6 associated), 81% survived (8 isolated and 5 associated). The median birth weight was 3,140 g and 2,000 g for survivals and non-survivals after surgery, respectively (p = 0.148), and the corresponding gestational age at delivery was 37 and 36 weeks (p = 0.836). The ratio of omphalocele/abdominal circumference decreased with gestation, 0.88 between 25-29 weeks and 0.65 between 30-35 weeks (p = 0.043). The size of omphalocele was not significantly different between the 3 groups (p = 0.988), and it was not associated to postsurgery prognosis (p = 0.553). Conclusion: the overall and postsurgery survival rates were 25 and 81%, respectively. Associated malformations were the main prognostic factor in prenatally diagnosed omphaloceles, since they are associated with prematurity and low birth weight.

Purpose: to estimate growth curves and tables of average biparietal diameter and average head circumference of twin gestations and to compare them with published growth curves for singletons and twins. Methods: growth curves and tables of average biparietal diameter and average head circumference were obtained from sonographic examinations of 34 patients with twin gestations without maternal and fetal complications. Sonographic examinations were performed each 2 or 3 weeks by a single observer. The parameters were compared with existing growth curves for singletons and twins. Results: curves and tables of biparietal diameter and head circumference in relation to gestational age were obtained. The study revealed difference in growth pattern mainly regarding the 3rd trimester in relation to singletons (Hadlock et al.15). The difference between the average values were 6 mm (biparietal diameter) and 2.0 cm (head circumference) at the 39th week of gestation. Also, some differences were observed relative to the twin studies. Conclusion: this study revealed that growth curves for average biparietal diameter and average head circumference of singletons are not appropriate to determine gestational age in twin gestations of the studiced population principally at the 3rd trimester
