ABSTRACT

Objective To evaluate therapeutic results of radiofrequency endovenous obliteration (RFO) for the treatment of varicose veins of the lower limbs. Methods Fifty six cases (56 limbs) of primary greater saphenous vein tributary varicose veins were randomly assigned to RFO group (n=28) and conventional stripping operation group (n=28). In RFO group, the wall of the greater saphenous vein was treated at 85℃ with the catheter to occlude the whole length of the vein. The other 28 cases underwent stripping procedure. The scattered superficial varicose veins in calf in both groups were managed by phlebectomy. The number of surgical incision, postoperative pain, average hospital days and the short-term results were compared. Results Patients in RFO group have less surgical incisions and less postoperative pain, without subcutaneous hematoma. The average hospital stay was 2.5?1.00 days in RFO group compared to 4.14?0.85 days in stripping operation group. Conclusions RFO effectively obliterates the whole length of the great saphenous vein and is of less trauma,faster recovery, and less scars.
