    Abstract:
    Pulmonary embolism is a leading cause of death and morbidity in the perioperative period. To obtain a contemporary overview of the epidemiology of acute pulmonary embolism, a questionnaire was mailed to anesthesia department chair-persons at 179 hospitals in Japan. The 158 cases were reported from the 88 hospitals. The cause of embolism was thromboembolism 127, gas 13, fat 9, amniotic fluid 4 and tumor 3. The mortality rate for patients with thromboembolism was high (29%). Dyspnea was the most frequent symptom (60%) and hypotension was the most frequent clinical sign (54%). The signs which suggested massive pulmonary embolism, such as hypotension, cyanosis (53%), syncope (39%) and cardiac arrest (29%) were frequently seen. Most of the pulmonary embolisms occurred during the operation and within 7 days after the operation. The high risk factors associated with thromboembolism were age, malignancy, obesity and the type of surgery performed. Treatment performed included anticoagulation 81%, catecholamine infusion 66%, thrombolysis 14%, surgical embolectomy 8% and extra-corporeal circulation 4%. This study indicates that the perioperative pulmonary embolism is still associated with high mortality and requires an immediate diagnosis and intensive therapy.
