Abstract:Objective: To compare the clinical efficacies between encircling constriction of superficial femoral vein and simple superficial vein stripping in treatment of valve incompetence of the lower limb deep veins. Methods: Forty-eight patients with lower limb deep venous valve insufficiency and varicose veins admitted from March 2010 to January 2011 were randomly assigned to observation group (undergoing encircling constriction of superficial femoral vein combined with high ligation and stripping of the great saphenous vein) and control group (receiving high ligation and stripping of the great saphenous vein only). The inner diameter and average blood flow velocity of the common femoral vein and venous reflux time in response to Valsalva maneuver of the patients in the two groups were measured by color Doppler sonography before and after operation. Results: Compared with the data before operation, the function of venous valves and hemodynamic state of the patients in both groups were significantly improved after operation, as evidenced by the reduced inner diameter and accelerated average blood velocity of the common femoral vein and shortened venous reflux time (all P<0.05). However, the changing amplitudes of the above three variables before and after operation in observation group were all significantly greater than those in control group (all P<0.05). Conclusion: Both of the encircling constriction technique and simple superficial vein stripping procedures are effective for treatment of lower limb deep venous valve insufficiency, while the efficacy of encircling constriction technique is superior to that of simple superficial vein stripping.
