Transhepatic Cannulation for Venovenous Extracorporeal Membrane Oxygenation.

Limited vascular access because of vessel injury or thrombosis may complicate care of children with congenital heart disease. Although transhepatic venous access for cardiac catheterization and central venous catheter placement has been used in children, its use for extracorporeal membrane oxygenation (ECMO) has not been described. We report successful use of transhepatic cannulation for venovenous ECMO to support a 15 month-old child with bidirectional Glenn anatomy and intractable hypoxemia.
