title: Pulmonary edema after catastrophic carbon dioxide embolism during laparoscopic ovarian cystectomy.
abstract: Laparoscopy is a surgical procedure used both for diagnosis and for various treatments. A rare but sometimes fatal complication of laparoscopy is pulmonary embolism with CO2 resulting in pulmonary edema. During laparoscopic gynecological surgery in a 29-year-old woman who had previously undergone lower abdominal surgery, the end-tidal CO2 suddenly increased from 40 mmHg to 85 mmHg and then decreased to 13 mmHg with hemodynamic deterioration. These events are characteristic of a CO2 embolism. When this occurred, CO2 insufflation was immediately stopped and the patient was resuscitated. The patient's condition gradually improved with aggressive treatment, but the clinical course was complicated by bilateral pulmonary edema. This case of pulmonary edema was soon resolved with supportive management. The formation of a CO2 embolism during laparoscopy must be suspected whenever there is a sudden change in the end-tidal CO2. In addition, the possibility of pulmonary edema should be considered when a CO2 embolism occurs.
