Abstract
PURPOSE: Extracorporeal life support (ECLS) is applied to refractory pulmonary hypertension in congenital diaphragmatic hernia (CDH). We evaluate the single-center outcomes of infants with CDH to determine the utility of late repair on ECLS versus repair post-decannulation. METHODS: Records of infants with CDH (2004-2014) were retrospectively reviewed. RESULTS: CDH was diagnosed in 177 infants. Sixty six (37%) underwent ECLS, of which, 11 died prior to repair, 33 were repaired post-decannulation, and 22 were repaired on ECLS. Repair was delayed in patients on ECLS (19 versus 10 days, p < 0.001). Patients repaired on ECLS had longer ECLS runs (22 versus 12 days, p < 0.001) and higher rates of bleeding and mortality than those repaired post-decannulation. Survival was 54% in infants undergoing ECLS, 65% in those who underwent repair, 36% in those repaired during ECLS, and 85% in those who were decannulated prior to repair. Eighteen percent (N = 4) of deaths after repair on ECLS were attributable to surgical bleeding. The remainder was due to pulmonary hypertension or sepsis. CONCLUSION: Infants who underwent CDH repair post-decannulation had excellent outcomes and no mortalities attributable to repair. Neonates who underwent repair on ECLS late on bypass had the lowest survival rate with only 18% of mortality in this cohort attributable to surgical bleeding.
