Pulmonary artery patch for an inadequate donor atrial cuff in the absence of donor pericardium in lung transplantation.

In cadaveric lung transplantation (LTx), a donor lung with an inadequate donor left atrial cuff is considered a "surgically marginal donor lung". The donor pericardium is commonly applied to reconstruct the inadequate donor left atrial cuff; however, in some cases, the donor pericardium is inadvertently removed during the lung procurement. We devised an alternative technique for reconstruction to overcome the absence of pericardium in a donor lung with an inadequate atrial cuff, using a patch of the donor pulmonary artery (PA) in single lung transplantation. In a recent case of lung transplantation in which the donor pericardium had been removed, we harvested a segment of the right PA distal to the main PA of the donor and used a PA patch to repair the inadequate donor left atrial cuff. No vascular complications were encountered in the recipient, who remains in good health after the transplantation.
