Acute Postoperative Negative Pressure Pulmonary Edema Caused by the Compression of Brachiocephalic Artery

: We report a case of negative-pressure pulmonary edema occurring by tracheal obstruction caused by the brachiocephalic artery. The patient had deformed thorax with cerebral palsy, which deformed thorax placing the brachiocephalic artery high over the trachea, resulting in close and tight contact between the artery and trachea. Additional deformity of the thorax associated with myotonic attacks after general anesthesia might shorten the distance between the sternal notch and the vertebral body, resulting in the tracheal obstruction by the artery.
