The clinical value of color doppler flow imaging in diagonosis of perforating venous insufficiency of the lower extremity

Objective:To investigate the clinical value of color Doppler flow imaging(CDFI) in diagonosis of perforating venous insufficiency of the lower extremity.Methods:The clinical data of 64 cases(82 limbs) undergoing high ligation and striping of great saphenous vein and perforator surgery were reviewed retrospectively.The dilated and insufficient perforating venous were diagnosed and located by CDFI.The results were compared with surgery.Results:Total consistent rate,sensitivity,specificity,omission diagonostic rate,mistake diagnositic rate,Youden index,Odd product,positive predictive value,negative predictive value,and Kappa of CDFI in diagnosis of perforating venous insufficiency of the lower extremity was respectively 95.8%、96.5%、88.2%、3.5%、11.8%、0.837、206.5、98.8%、71.4% and 0.766(P0.0001).The CDFI foundings were consistent with operation results very well.Conclusion:CDFI is a useful technique for the diagnosis and locating the dilated and insufficient perforating venous correctly and provide important basis for the operation.
