Abstract

Objectives We aimed to compare the level of significance of risk factors related Intraventricular hemorrhage (IVH) between preterm infants born after IVF and non-IVF conceptions. Materials & Methods This historical cohort study was done in four Iranian Hospitals in 2013-2014. Overall, 155 preterm newborns were divided into case (IVF) and control (normal conception) groups. Both groups’ demographic data were extracted and recorded. The incidence of IVH and its grades were compared between case and control groups. Significant related risk factors were also considered. Results No differences were observed between 2 groups except for gestational age and mode of delivery. The incidence of IVH especially grades II and III were significantly higher in the case group (P=0.003). Results showed no correlations between Gestational age (GA), birth weight and number of gestations with the incidence of IVH in the case group (0.059, 0.85 and 0.49, respectively). On the other hand, among GA, birth weight and number of gestations; multi gestations (P=0.0001) was an effective risk factor for IVH occurrence in the controls. Conclusion The incidence of IVH in the IVF group was significantly higher than in the non-IVF group. IVF as an independent risk factor may cause high-grade IVH; however, in the controls, multi gestational pregnancy (P=0.0001) was an effective risk factor for IVH occurrence. © 2019, Iranian Child Neurology Society.
