- W2383596893 abstract "Objective To evaluate the therapeutic effect of individualization of constriction proportion using external valvuloplasty of the first pair of superficial femoral vein with expanded polytetrafluoroethylene (ePTFE) implants for primary deep venous insufficiency (PDVI) in lower extremities. Methods External valvuloplasty of the first pair of superficial femoral vein was performed on 54 cases (56 limbs). Individualized proportion of constriction was adopted according to the degree of the venous blood reflux via the valve. Results Intraoperative examination showed that the valve competence rate achieved in 96.4% of 56 limbs after the valvuloplasty was finished. Fifity-five limbs were followed up with a mean period for 23 months( 14 months 35 months). Clinical symptomatic improvement acchived in 94.5% of the limbs. The valve competence recover rate was 85.5% comfirmed by color ultrasounoraphy.There are no statistically differences of the valve competence recover rates between the mild and the moderate PDVI groups (P0.05). The valve competence recovery rate in severe PDVI group was significantly lower than that of the mild and moderate PDVI groups (both P0.05). Conclusions The results suggest that the individualized proportion of constriction should be adopted in external valvuloplasty of the first pair of superficial femoral vein, especially for the the limbs with the mild or moderate PDVI. The individualization of constriction proportion is feasible and effective for PDVI of lower extremity." @default.
