Contralateral pulmonary artery banding after single lobar lung transplantation.

A 14-year-old female patient underwent right single living-donor lobar lung transplantation for bronchiolitis obliterans after bone marrow transplantation. The patient experienced a complication with severe hypoxemia requiring venovenous extracorporeal membrane oxygenation, which appeared to result from significant ventilation-perfusion mismatch caused by preferential ventilation of the transplanted lobe and relatively preserved perfusion to the native lung. On day 2, we performed left pulmonary artery banding, which significantly improved oxygenation leading to weaning from extracorporeal membrane oxygenation. Our experience indicates that contralateral pulmonary artery banding may be a feasible option to rescue patients from hypoxemia resulting from ventilation-perfusion mismatch after single living-donor lobar lung transplantation.
