Abstract
Objective: The main objective of the study was to determine if ultrasonographic measurement of mediastinal shift angle (MSA) can predict postnatal survival in fetuses with isolated left congenital diaphragmatic hernia (CDH). This relatively new technique may be used to enhance antenatal prediction of survival in fetuses with CDH.
Methods: A retrospective cross-sectional study was conducted at the Philippine Children’s Medical Center involving 16 cases with prenatally diagnosed isolated left CDH and 60 controls with normal fetuses. The cases with prenatally diagnosed isolated left CDH were allocated into two groups: Group A (survivors) and group B (non-survivors). For all fetuses (study and control groups), MSA was determined independently by two operators. The diagnostic capacity of MSA was assessed using the receiver operating characteristic curve.
Results: The mean MSA for the control group was 17.18°. Among CDH cases, the mean MSA was 33.04° and 37.57° for survivors and non-survivors, respectively. Results showed that MSA significantly predicted the probability of neonatal survival status (OR = 0.46, P = 0.021). The best cutoff score of MSA based on the receiver operating characteristic curve was 33.80° with 87.50% sensitivity and specificity.
Conclusion: MSA has the potential to enhance antenatal prediction of survival in fetuses with CDH and may serve as a guide in prenatal counseling and evaluation of the need for in-utero treatment or postnatal procedures.
