Study of encircling constriction of superficial femoral vein in the treatment of primary deep venous insufficiency with the help of Color Doppler

Objective To study the effect of Color Doppler in encircling constriction of superficial femoral vein in the treatment of primary deep venous insufficiency (PDVI).Methods Eighty-seven limbs in 87 patients who were proved to be PDVI by ascending venography were divided into Group A (44 limbs) and Group B (43 limbs).All the patients were treated with the encircling constriction of venous wall at the first valve of superficial femoral veins and the high ligation and ablation of great saphenous vein,ablation of superficial veins and ligation of perforator veins.But during the operations of patients in Group A,we used Color Doppler to help us.We used lasting time of reflux flow of vein to evaluate the short time effect.CEAP classification and clinical scoring were proceeded from two months to six years after operation to evaluate the long time effect.Results In patients in Group A the lasting time of reflux flow was markedly shortened.The results of CEAP indicated that obviously effective rate of Group A was 95.00 %(38/ 40) while it was 76.74%(33/43) in Group B.The difference between two groups’ effective rate was significant (P0.01).The difference between preoperative and postoperative clinical scores of Group A and Group B were both remarkable.between Group A and Group B were also prominent (P0.01)Conclusion Appling of Color Doppler is useful to promote the effective rate in the operation encircling constriction of superficial femoral vein in the treatment of PDVI.
