- Abstract
To investigate changes in the size of the deep and superficial venous systems associated with gender, age, body mass index and varicose veins, changes to the cross-sectional area of the femoral and the long saphenous veins were analysed in the Duesseldorf/Essen civil servant study population. Between December 1989 and July 1993 a total of 9935 employees were recruited; 9261 were then evaluated for this analysis. Diameters of the long saphenous and femoral veins were determined 23 cm distal to the con uence in lying (after 15min rest) and standing (after 5 min) positions. Cross-sectional areas (CSA) were calculated. A total of 63% of all people were assigned to CEAP (clinical, etiological, anatomical pathophysiological) class 0, 27% to class 1, 8.5% to class 2, while 1.5% belonged to higher CEAP classes. In people without varicose veins (CEAP class 0) the CSA of the femoral and long saphenous veins were smaller in females than in males. In people with a normal body mass index (BMI) (2025) the mean CSA of the femoral and long saphenous veins in a standing position was similar from the third up to the sixth decadeof life. The volume increase due to a standing position expressed as the absolute increase in CSA of the femoral and long saphenous veins was not age-related, either. The relative volume increase expressed as a ratio remained unchanged with age. There was a strong relationship between the CSA of both veins and increasing BMI. In a lying position, the CSA of the femoral and long saphenous veins increased only slightly with increasing CEAP classes. In a standing position, the CSA of both veins increased even in CEAP class 1 (p < 0.001). In a stepwise multivariate regression analysis, the CSA of both veins in a standing position was not age-related but associated with BMI, CEAP classes and gender. The absolute increase in CSA was in uenced by all four variables, but BMI and gender were most important. In Conclusion, this study shows that aging is not necessarily associated with an increase in venous CSA of the deep and super cial venous system. BMI is the most important determinant for an increase in CSA in standing position. Varicosity of the super cial venous system is always associated with similar changes in the deep venous system.
