title: [Anesthesia for patients with unexpected pulmonary embolisms due to a large abdominal tumor obstructing with inferior vena cava].
abstract: Several reports have highlighted the risk of pulmonary embolisms during the preoperative period in patients with large abdominal tumors obstructing the inferior vena cava. We describe a patient who developed pulmonary embolism just before surgery. A 68[correction of 64]-year-old female was scheduled to undergo elective resection of a large abdominal tumor under general anesthesia. She had no signs of deep venous thrombosis, but on the day of the operation, pulmonary embolism developed suddenly. Anticoagulant therapy was performed. Capnography and pulmonary artery pressure were monitored during the perioperative period to detect the recurrence of pulmonary embolism. The percutaneous cardio-pulmonary support (PCPS) was also prepared. The operation was performed successfully. In this patient, the pulmonary embolism occurred suddenly during the preoperative period, even though we had ruled out the existence of deep venous thrombosis. This case report emphasizes the risk of pulmonary embolism in any patient with a large abdominal tumor obstructing the inferior vena cava. This case of a large abdominal tumor suggests that capnography, monitoring of pulmonary artery pressure and preparation of a PCPS in case of pulmonary embolism during surgery are necessary even in patients without signs of deep venous thrombosis.
