Venous Thromboembolism (VTE) is a complication of surgery that may result in sudden death. Unfortunately there is not a reliable model for it up to now where with accurate modeling can be prevented serious these complications. In this paper (VTE) has been model in fuzzy method. At first we have used expert knowledge for modeling. Therefore for beginning risk factors of (VTE) have been identified and then we have helped from papers and scientific references and consultation with surgeons to extract importance of these factors in risk of VTE. Then we have obtained a questionnaire for fuzzy modeling. In this questionnaire all factors are divided into five groups. Each group is designed as a separate fuzzy system. The final output is calculated by community of all groups. Finally we validate this system by data of patients that have been surgery in Shariati hospital in Tehran and you can see that it works appropriately.
