    Abstract:
    OBJECTIVE: To evaluate the therapeutic effect and the clinical practicability of encircling constriction of superficial femoral vein in the treatment of primary deep venous insufficiency (PDVI). METHODS: Ninety-seven limbs in 97 patients who were proved to be PDVI by ascending venography were divided into Group A (79 limbs) and Group B (18 limbs). Patients of Group A were treated with the encircling constriction of venous wall at the first valve of superficial femoral veins. And they were also treated with the high ligation and ablation of great saphenous vein, ablation of superficial veins and ligation of perforator veins at the same time. Patients of Group B were simply treated with the high ligation and ablation of great saphenous vein, ablation of superficial veins and ligation of perforator veins. Ascending venography and CEAP classification and clinical scoring were proceeded from two months to six years after operation to evaluate the effect of the operation. RESULTS: The difference between preoperative and postoperative scores of Group A and Group B were both remarkable (Group A, P < 0.01; Group B, P < 0.05). The difference of scores, which equated to preoperative scores minus postoperative score, between Group A and Group B were also prominent (P < 0.01). Post-operation ascending venography was performed on 67 limbs in Group A. The effective rate of the operation is 83.58% (28 + 28/67), obviously effective rate is 41.79% (28/67). Same exam was performed on 12 limbs in Group B and the effective rate of the operation is 33.33%. The difference between two groups' effective rate is significant (P < 0.05). CONCLUSIONS: Clinical scoring of Group A decreased much more than Group B; The effective rate of Group A in ascending venography is also much higher than Group B. Encircling constriction of superficial femoral vein is useful to relief the symptom and recover the shape and function of the valve of superficial femoral veins. Those who are diagnosed to be PDVI by means of pre-operation ascending venography and Valsalva test should accept the operation of the encircling constriction of superficial femoral vein.
