Abstract:
Objective To determine the perinatal outcomes and its risk factors of fetuses prenatally diagnosed with the double bubble sign on ultrasound scanning.Methods The clinical data of 57 cases of fetal double bubble sign which was prenatally diagnosed by ultrasound in Xin Hua Hospital from January 1,2000 to December 31,2013 were retrospectively analyzed.The neonates survived not less than 42 days were as surviving group,and who survived lower than 42 days were as dead group.The t test,x2 test and Logistic regression were used for statistical analysis of the data.Results Of 57 fetuses with the double bubble sign,the incidence of polyhydramnios,intrauterine fetal death and associated anomalies was 88％ (50/57),4％ (2/57) and 23％ (13/57),respectively.Induced labor to terminate the pregnancy was occurred in eight cases,the other 49 cases had live births but ten neonates abandoned therapy.Thirty-nine live babies accepted surgical treatment with one dead,and the other 38 neonates survived not less than 42 days.The overall 42-day survival rate was 67％ (38/57) and the surgical survival rate was 97％ (38/39).Compared with surviving neonates,the neonates who died had lower gestational age [(35.8±3.0) vs (38.1 ± 1.9) weeks,t=2.859,P＜0.01] and birth weight [(2 229±567) vs (2 830±558) g,t=3.136,P＜0.01],and a higher incidence of prenatally diagnosed structural anomalies [3/11 vs 3％ (1/38),P＜0.05] and karyotype anomalies detected after birth [3/11 vs 3％ (1/38),P＜0.05].Logistic regression analysis showed that the fetuses with the double bubble sign and fetal growth restriction had a higher risk of complications (OR=9.893,95％CI:1.758 55.661,P=0.009).Conclusions Fetuses with double bubble sign have adverse outcome if they complicating preterm delivery,low birth weight,prenatally diagnosed structural anomalies and karyotype anomalies.
