Venous air embolism (VAE) is a well known complication in procedures where the operative field is above the level of the heart. Acute pulmonary oedema after a large air embolus occurring during neurosurgery is also a recognized phenomenon. However, pulmonary oedema following repeated episodes of VAE in sublabial transsphenoidal (SLTS) surgery for pituitary adenoma has never been reported. We describe a case of VAE in a 65 year old male undergoing SLTS surgery for pituitary adenoma. Following this, the patient had pulmonary oedema which resolved on supportive treatment. Pulmonary oedema as a result of VAE may go unrecognised intraoperatively but can lead to a significant postoperative morbidity. Early suspicion and recognition of VAE and institution of aggressive treatment will help to avoid fatal consequences.

We describe a case of negative pressure pulmonary edema that occurred in the post-anesthesia care unit in a patient who had undergone transsphenoidal resection of a pituitary adenoma. Negative pressure pulmonary edema is an uncommon complication of general anesthesia. In this case, the patient's nasal cavity had been filled with surgical packs and she had not become accustomed to breathing through her mouth, in addition to her large tongue and small oropharyngeal cavity, residual effect of anesthetic may resulting in tongue falling which caused airway obstruction. The main causative factor is excessive negative intrathoracic pressure generated by the patient's spontaneous forced inspiration in an effort to overcome the airway obstruction. It typically developed rapidly, and may be life threatening if not diagnosed promptly. After re-intubation for a short period of mechanical ventilation with positive end expiratory pressure (PEEP 10 cm H2O) and a bolus of intravenous furosemide, the patient recovered rapidly and discharged 8 days after surgery.
