Thrombotic diseases are a serious problem for public health. Several hereditary and environmental factors, that affect physiological anticoagulant system, have been nowadays well established as risk factors for thrombosis. Among hereditary factor V Leiden and prothrombin G20210A mutation are the most frequents. The association between several modifications on factor V gene and prothrombin gene in the development of thrombotic events has brought about future searches. In this study, 189 patients with thrombosis attended at the Hematology and Hemoterapy Center of Ceará state –HEMOCE/ Brazil, were analyzed to find out the presence of factor V Leiden and prothrombin G20210A mutation The control group was made up 349 healthy volunteers. In this study, the frequency found of factor V Leiden the control population was of 2% (7/349) and in the patients was 9% (17/189) while the frequency found of prothrombin G20210A mutation the control population was of 1,7% (6/349) and in the patients was 2,1% (4/189). Among hereditary factors only factor V Leiden was significant statistic (p<0,001). Among environmental factors studied, tabagism, age > 40 anos and femele were significant statistic (p<0,001). The ODDS RATIO of the risk factors with significant statistic were factor V de Leiden (4,8; 5,3; 9,8), tabaco (17,6; 14,9; 33,3), age > 40 years old (2) and female (3,7 e 4,1). Our results demonstrate that factor V Leiden, tabagism, age > 40 years old and female were associated with development trombosis in Ceará.
