Successful Lung Transplant After Prolonged Extracorporeal Membrane Oxygenation (ECMO) in a Child With Pulmonary...

Area of Science:

• Pediatric critical care medicine
• Cardiopulmonary support
• Lung transplantation

Background:

• Extracorporeal membrane oxygenation (ECMO) is often viewed as a risk factor or contraindication for lung transplantation (LT), with limited pediatric case reports.
• Idiopathic pulmonary arterial hypertension (PAH) presents significant challenges in pediatric patients requiring advanced life support.

Observation:

• A 9-year-old boy with idiopathic PAH experienced cardiac arrest and required ECMO as a bridge to lung transplantation.
• The patient developed medullary ischemia and medullary syndrome following prolonged resuscitation and ECMO support.
• Despite complications, the patient was successfully weaned from ECMO after 6 weeks and underwent bilateral lung transplantation.

Findings:

• The patient demonstrated significant recovery, with alleviation of medullary syndrome and minimal post-transplant issues at 4 years.
• Successful weaning from prolonged ECMO support was achieved, enabling subsequent lung transplantation.
• The patient returned to school and regained ambulation with aids, indicating substantial functional recovery.

Implications:

• Prolonged ECMO support is feasible as a bridge to lung transplantation in pediatric patients with severe pulmonary hypertension.
• This case highlights the potential for good outcomes despite ECMO-related complications, emphasizing the need for specialized management.
• Further research and experience are necessary to fully understand the long-term outcomes and optimize the use of ECMO in pediatric lung transplantation.
