    Journal: Zhonghua Wai Ke Za Zhi; 2000 Jan; 38(1):22-4. PubMed ID: 11831979.
    Abstract:
    OBJECTIVES: To assess the scope of photoplethysmography (PPG), color duplex ultrasonography, percutaneous transpopliteal venography for evaluating chronic venous disease. METHODS: Color duplex ultrasonography, percutaneous transpopliteal venography, and PPG and were used in 40 patients their results were compared. RESULTS: Color duplex ultrasonography and percutaneous transpopliteal venography for evaluating venous reflux was not significant (P > 0.05) in the femoral-popliteal venous segment. The accuracy of PPG in evaluating venous reflux was 67% compared with that of color duplex ultrasonography. CONCLUSIONS: PPG as the first test is often used for chronic venous disease. Color duplex ultrasonography can provide sufficient information for treatment of patients the. Percutaneous transpopliteal venography is necessary when noninvasive test can not provide sufficient information.
