Management of Partial Anomalous Pulmonary Venous Return In Lung Transplantation.

This report describes the case of a patient who underwent bilateral lung transplantation for idiopathic pulmonary arterial hypertension with coexisting partial anomalous pulmonary venous return and tracheal bronchus. The hypoplastic and low-positioned left atrial orifice caused by abnormal reflux of the right upper pulmonary vein and high-positioned right upper lobe bronchus made right anastomosis challenging. To prevent excessive tension on left atrial anastomosis, the donor's right main bronchus was anastomosed to the recipient's bronchus intermedius, a maneuver that resulted in successful anastomosis and an uneventful postoperative course.
