Purpose: Lung hypoplasia is associated with mortality in congenital diaphragmatic hernia (CDH). However, the association between lung hypoplasia and disease severity is unclear. Early prediction of disease severity would provide parents with more precise information about the anticipated course of treatment, minimize treatment disruption, and maximize the efficient management of patients with CDH. We aimed at identifying the relationship between McGoon index (MGI) and pulmonary artery index (PAI) scores and disease severity among infants with CDH. Methods: We retrospectively reviewed the medical records of 19 high-risk patients with CDH born between January 2006 and December 2007. McGoon index and PAI scores were determined on admission. We evaluated statistically the relationship between these scores and variables representing severity as follows: number of vasodilators, use of inhaled nitric oxide (iNO), closed method of diaphragm, duration of intubation, duration of hospitalization, and use of home oxygen therapy. Statistical significance was P < .05. Results: Overall median MGI and PAI scores were 1.40 and 108, respectively; scores for nonsurvivors were significantly (P < .05 and P < .01, respectively) lower than those for survivors. Among survivors, PAI scores were significantly (P < .05) lower in infants requiring iNO than in infants not requiring iNO and patch repair. The PAI scores were significantly correlated with the number of vasodilators (r = -0.789; P < .01) and duration of intubation (r = -0.610; P < .05). Conclusions: McGoon index (cutoff value, 1.31) and PAI (cutoff value, 90) are reliable indices for predicting mortality in CDH. Pulmonary artery index appears to be more useful than MGI for predicting disease severity among survivors.
