A case of bilateral diaphragmatic injury following resection of anterior mediastinal tumor]

A 58-year-old woman was scheduled for resection of anterior mediastinal tumor. Prolonged mechanical ventilation was required following surgery because of bilateral diaphragmatic injury. Pleural effusion, atelectasis, and syndrome of vena cava superior were observed during the treatment. BiPAP was useful for respiratory support. The patient was discharged from our hospital nine months after surgery. Oxygen therapy was not necessary in the day time. But the patient required respiratory support with BiPAP at night.
