Continuous Venovenous Hemodialysis Via Extracorporeal Membrane Oxygenation Pump for Treatment of Hyperammonemia Secondary to Propionic Acidemia in Monochorionic Diamniotic Twin Boys

Abstract

Late-preterm twins with propionic acidemia developed severe hyperammonemic encephalopathy at 5 days of age. Continuous venovenous hemodialysis was performed successfully for both infants via extracorporeal membrane oxygenation pump, and both rapidly improved. They were taken off continuous venovenous hemodialysis and extracorporeal membrane oxygenation and discharged with dietary therapy. At 3 years of age, neurodevelopment showed globally delayed milestones.
