Abstract

Background: Thrombophilia is increasingly recognized as a risk factor for deep venous thrombosis (DVT), which in turn is a major risk factor for chronic venous ulceration (CVU). However, the relationship between thrombophilia and CVU remains unknown. The aim of this study was to define the prevalence of thrombophilia in patients with CVU and to determine whether this is associated with a history or duplex scan evidence of DVT. Methods: Eighty-eight patients with CVU were prospectively studied. The patients underwent clinical assessment and duplex ultrasound scanning. Blood was drawn for antithrombin, proteins C and S, activated protein C resistance, factor V Leiden, prothrombin 20210A, lupus anticoagulant, and anticardiolipin antibodies. Results: The study included 35 men with a median age of 61 years (interquartile range, 45 to 72 years) and 53 women with a median age of 76 years (interquartile range, 69 to 82 years). Thirty-six percent of the patients had either a history or duplex scan evidence suggestive of previous DVT. The following abnormalities were detected: four, five, and six cases of antithrombin, protein C, and protein S deficiencies, respectively; 14 cases of activated protein C resistance; 11 cases of factor V Leiden mutation; three cases of prothrombin 20210A mutation; eight cases of lupus anticoagulant; and 12 cases of anticardiolipin antibodies. Thrombophilia was not significantly related to previous DVT, deep reflux, or disease severity. Conclusion: Patients with CVU have a 41% prevalence rate of thrombophilia. This rate is two to 30 times higher than the rate of the general population but is similar to that reported for patients with previous DVT. However, in patients with CVU, thrombophilia does not appear to be related to a history of DVT, a pattern of reflux, or severity of disease. Many patients with CVU may have unsuspected postthrombotic disease. (J Vasc Surg 2002;35:718-22.)
