Fig. 5. Survival rates of fetuses with isolated left-sided congenital diaphragmatic hernia as a function of the observed/expected lung:head ratio (O/E LHR) and liver position as in the antenatal congenital diaphragmatic hernia registry. Figure modified from Deprest et al, 2009, with permission. Arrows and horizontal lines indicate observed survival rates following FETO for severity matched fetuses as reported by the FETO consortium (Jani et al., 2006).
