Hypoxemia after general anesthesia is not uncommon. For patients after thoracotomy, the differential diagnosis is usually difficult. Surgical, anesthetic, and patient-associated factors may contribute to postoperative hypoxemia. We described two patients who underwent video-assisted thoracoscopic thymectomy and developed hypoxemia immediately after extubation. Phrenic nerve injury was suspected in both patients. One case recovered spontaneously without intervention. The second case who had been demonstrated as bilateral phrenic nerve injury after the operation was continuously on ventilator after physical therapy and respiratory training for 2 months.

Key words: Phrenic nerve injury, hypoxemia, video-assisted thoracoscopic surgery
