title: Risk Factors in Patients with Venous Stasis-Related Skin Lesions without Major Abnormalities on Duplex Ultrasonography.
abstract: Purpose:To clarify the risk factors for venous stasis-related skin lesions in the legs in patients without major abnormalities on duplex ultrasonography (DUS).Methods:Fifty patients (nine males and 41 females, age 27-93 years) with symptoms of C4 or greater according to the Clinical, Etiological, Anatomical, Pathological (CEAP) classification, but having no abnormalities on DUS were reviewed for known risk factors for chronic venous insufficiency (CVI) such as older age (>70 years), obesity (body mass index [BMI] >30 kg/m2), short walking distance (<200 m/day), reduced ankle range of motion (<20°), and occupation requiring prolonged standing (>8h per day).Results:The risk factor was different between male and female patients; although all patients had at least one of the above risk factors, the most commonly found risk factor in male patients was occupation requiring prolonged standing (63%), while advanced age (78%) and limited walking distance (83%) were risk factors in female patients.Conclusions:Although male and female patients had different risk factors, insufficient walking seemed to be closely related to the development of venous stasis-related skin lesions.
