Veno-venous extracorporeal membrane oxygenation in the management of refractory bilateral bronchial dehiscence after lung transplant: a case report

Background
Bronchial dehiscence is a life-threatening complication after lung transplant. If it is not treated by placement of stent or reanastomosis, the chance of survival will depend on the availability of a new graft. However, retransplant is not a practical management option in Japan, where waiting time for lung transplant is extensive. We described a case of refractory bilateral bronchial dehiscence managed by veno-venous extracorporeal oxygenation membrane (VV ECMO) while allowing the dehiscence to heal.

Case presentation
A 25-year-old man with idiopathic pulmonary arterial hypertension underwent a bilateral lung transplant. The patient developed bilateral bronchial dehiscence. Open reanastomosis was not successful, and air leakage recurred under low positive pressure ventilation. VV ECMO was established to maintain oxygenation with spontaneous breathing until both dehiscence were closed by adhesions.

Conclusion
In a patient with refractory bilateral bronchial dehiscence, VV ECMO may provide bronchial rest and serve as a bridge therapy to recovery.
