Abstract

Background: Right congenital diaphragmatic hernia (CDH) occurs less frequently than left CDH. Therefore, prognostic indicators for right CDH are not as well studied as for left CDH. Methods: A retrospective review from a single, tertiary referral center (from 1994 until July 2013) of patients with unilateral right CDH was conducted. Prenatal characteristics were evaluated and correlated with survival to discharge and need for extracorporeal membranous oxygen (ECMO). Results: In total, 34 patients were identified. There were 12 postnatal deaths and 2 fetal demises (6%), representing an overall mortality of 41%. Six patients required ECMO. Nine patients underwent fetal intervention and were analyzed separately. For patients not undergoing fetal intervention, the survival rate was 52% and a higher mean (±SD) lung-to-head ratio (LHR) was associated with survival (1.1 ± 0.4 vs. 0.8 ± 0.2, p = 0.03). There were no deaths or need for ECMO in any patient with an LHR ≥1.0. Of the 9 patients who underwent fetal intervention, survival was 78% and only 1 patient required ECMO. Fetal intervention was primarily tracheal occlusion (n = 8). Conclusions: An LHR <1.0 is associated with worse survival for right CDH and may also reflect the need for ECMO.
