AbstractWe report a successfully treated case of unilateral absence of a pulmonary artery, associated with an atrial septal defect and chronic lung disease with severe pulmonary hypertension. Because this severe pulmonary hypertension could jeopardize postoperative hemodynamic, the ingenuity of surgical strategy was required. The atrial septal defect was left open as a safety "pop-off" valve, and prosthetic graft was chosen as a reconstructive material to avoid excessive dilatation from exposure to unpredictable postoperative pulmonary hypertension.
