Extracorporeal membrane oxygenation as a bridge to lung transplantation in a patient with persistent severe porto-pulmonary arterial hypertension following liver transplantation

Abstract

Idiopathic pulmonary artery hypertension (IPAH) is a progressive disease with a dismal prognosis and lung transplantation is often the only option for patients, who do not respond to pharmacological therapy. We report the use of an extracorporeal membrane oxygenation (ECMO) system in a 49-year-old woman with primary pulmonary hypertension, previously liver transplanted. The patient, listed for lung transplantation, developed respiratory and circulatory failure despite maximal pharmacological therapy and was successfully bridged to emergent bilateral lung transplantation with veno-arterial ECMO. Emergent veno-arterial ECMO was able to rescue the patient and bridge her to bilateral lung transplantation and should therefore be an option for patients with PAH and circulatory collapse.
