BACKGROUND: Authors report an epidemiological analysis of the investigation on thrombophilic factors in patients presenting with arterial and/or venous thrombotic events followed at the Angiology and Vascular Surgery Department at CENTERVASC, from January 2001 to January 2007. OBJECTIVE: To assess the prevalence of congenital or acquired thrombophilic markers in venous and/or arterial thrombotic events. METHODS: From January 2001 to January 2007, 224 patients with venous and/or arterial thrombotic events were screened for the presence of congenital or acquired thrombophilic markers independently of age and family history, location of thrombus and presence or absence of other thrombogenic factors. RESULTS: Thrombophilic factors were present in 112 patients (50% of the cases), in whom predominant positive results for antiphospholipid, anticardiolipin and/or lupus anticoagulant antibodies (39 cases) as well as the presence of factor V Leiden (43 cases) were observed. The venous system was the most significantly affected, and other associated thrombogenic factors were present in 56 (50%) carriers of genetic thrombophilic factors. CONCLUSION: The presence of genetic thrombophilic factors in patients with venous and/or arterial thrombotic events, independently of age or presence of other associated factors, was significant.
