Satisfactory Results of Diaphragmatic Plication for Bilateral Phrenic Nerve Paralysis

Bilateral diaphragmatic plication was performed in a 44-year-old man who underwent complete resection of a thymoma infiltrating the right lung, bilateral brachiocephalic vein, pericardium, and bilateral phrenic nerves. The plication procedure allowed him to be weaned from the ventilator on postoperative day 4. He demonstrated no restrictive or obstructive pattern of lung function, and after respiratory rehabilitation he returned to work full time 5 weeks after the operation. The present results indicate that ventilatory movement of the thoracic cage can compensate for loss of bilateral diaphragmatic ventilation for at least 18 months.
