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 va1vular incompetence.展开更多
