    BackgroundAlthough we reported the perioperative mortality to be 4.41 (per 10000 cases) and morbidity to be 18.0% with the pulmonary thromboembolism (PTE) in Japan based on the research conducted by the Japanese Society of Anesthesiologists (JSA), the characteristics of these patients have not yet been assessed.MethodsResults of 809 registry cases of perioperative PTE patients were analyzed regarding the differences in gender, characteristics of obesity, cases that resulted in death, feature of PTE cases with abdominal surgery and hip/lower extremity surgery, and changes in the results of two researchs.ResultsConsiderably higher number of obesity cases were observed in women than in men, and the obesity rate was approximately 1.5-3-times higher in men than that observed in the general female population. The predictors of mortality were old age, long-term rest and gender (male). More than 80% of the patients who had undergone abdominal surgery contracted PTE in the postoperative period; but, more than 60% of the patients who had undergone hip/lower limb surgery along with a bone fracture contracted PTE in the preoperative or intra-operative periods. When compared with the results of the research carried out in 2002 and 2003, the incidence around caesarean section appeared to have decreased significantly (P = 0.016), and use of elastic stoking and intra-pneumonic compression appeared to have increased significantly (P<0.01). However, the rate of using anticoagulant drugs appeared to remain unchanged.ConclusionsThe results of this study indicate the clinical characteristics of patients with perioperative PTE in Japan, the predictors of perioperative mortality, and the changes observed between the results of the researches carried out in 2002 and 2003.
