Lobar torsion after lung transplantation.

Lobar torsion is a rare complication after lung transplantation. Here we report a case of right middle lobe (RML) torsion after bilateral sequential lung transplantation (BLTx). This 30-year-old lady underwent BLTx for bronchiolitis obliterans due to paraneoplastic pemphigus. The right lower lobe of the donor lung was resected due to inflammatory change during procurement. The postoperative chest X-ray showed persisting RML infiltrates. Fever and leukocytosis were noted 1 week later. RML lobectomy was performed after the reconstructed chest computed tomography confirmed the diagnosis of RML torsion. Adult respiratory distress syndrome with unstable vital signs, refractory hypoxemia and respiratory acidosis occurred thereafter. After venoarterial extracorporeal membrane oxygenation support, the patient recovered slowly and was discharged 5 months after BLTx.
