Abstract:
Objective To study the diagnostic value of air plethysmography (APG) in deep venous valvular incompetence of lower limbs and the relationship between deep venous reflux and calf muscular pump function. Methods Sixty-five varicose cases (89 limbs) were detected by APG in alterations of venous filling index (VFI), ejection fraction(EF), residual volume fraction(RVF) and outflow fraction(OF). Of 89 limbs, 18 limbs were in GradeⅠ of deep venous reflux, 24 in Grade Ⅱ, 18 in Grade Ⅲ and 12 in Grade Ⅳ. Integrated vectors analysis (Hotelling T 2test) was done with these index. Venography was performed in all patients. Results There were statistical differences in VFI between each two Grades of deep venous reflux except for between Grade Ⅰ and Ⅱ. There were also statistical differences in EF,RVF and OF between Grade Ⅳ and the other Grades. Hotelling T 2test showed significant testing efficiency of APG. ConclusionsDeep venous valvular insufficiency of lower limbs can be assessed by APG. VFI is a reliable quantitative index for evaluating the degree of deep venous reflux. There may be an exponent relation between deep venous reflux and calf muscular pump function.
