Application of color Doppler ultrasonic examination in deep vein valvular incompetence in lower limbs.
By use of color Doppler Flow Imaging (CDFI), the morphologic and hemodynamic parameters such as the diameters of femoral and popliteal veins, blood flow velocity and the reflux of valve area were examined in lower extremity deep valvular incompetence (DVI) and normal control groups. The purpose was to evaluate the value of CDFI in the diagnosis of DVI. The results demonstrated that the parameters between the two groups had a very significant difference (P < 0.001), indicating that the CDFI is non-invasive, cost-effective and safe and it might serve as a practical tool in the diagnosis of lower extremity deep valvular incompetence.
