Evaluation of encircling constriction of superficial femoral vein in the treatment of primary deep venous insufficiency

Objective To evaluate the effect of encircling constriction of superficial femoral vein in the treatment of primary deep venous insufficiency (PDVI) with CEAP classification and clinical scoring. Methods Ninety-seven limbs in 97 PDVI patients diagnosed by ascending venography were divided into Group A (79 limbs) and Group B (18 limbs). Patients in group A were treated with encircling constriction of venous wall at the first valve of superficial femoral veins added with high ligation and ablation of great saphenous vein, ablation of superficial veins and ligation of perforator veins. Patients in group B were simply treated with high ligation and ablation of great saphenous vein, ablation of superficial veins and ligation of perforator veins. CEAP classification and clinical scoring were proceeded from two months to six years postoperatively to evaluate the effect of the operation. Results The difference between preoperative and postoperative scores in group A and B were both remarkable (in group A: P0.01; in group B: P0.05). Scores in group A decreased more significantly (P0.01). Conclusions Encircling constriction of superficial femoral vein is useful to relieve the symptom of PDVI.
