ABSTRACT
Objective To investigate and analyze the effect of polyurethane foam sclerotherapy on varicose veins of lower extremity under the guidance of fluoroscopy. Methods 90 patients with varicose veins treated in our hospital from February 2015 to May 2017 were selected and randomly divided into the control group and the experimental group, with 45 patients in each group. The patients in the control group were given conventional high ligation and stripping of the great saphenous vein. The patients in the experimental group were treated with fluoroscopic guided polyurethane foam sclerotherapy. The therapeutic effects of the 2 groups were compared and analyzed. Results After operation, 2 patients relapsed in the experimental group, and the recurrence rate was 4.4％. In the control group, 6 patients relapsed. The recurrence rate (13.3％) in the control group was significantly higher than that in the experimental group, with statistical difference. After the corresponding treatment, the intraoperative blood loss in the experimental group was (10.23±1.52) mL, and the bleeding volume in the control group was (32.19±2.34) mL. The bleeding volume in the experimental group was significantly less than that in the control group, with statistical difference. In addition, the average length of stay, length of operation and length of incision in the experimental group were significantly better than those in the control group, with statistical difference. Conclusion The clinical effect of fluoroscopy guided lauromacrogol foam sclerosing agent in the treatment of varicose vein of lower limb is better, the recurrence rate is low, can significantly reduce the amount of bleeding, shorten operation time, has clinical significance.
