Abstract: Objective To evaluate the therapeutic effect of radiofrequency endovenous obliteration (RFO) on superficial varicosities in lower extremity in the elderly. Methods The clinical data of 35 elderly patients (43 limbs) with primary great saphenous varicose vein, who were treated with RFO (20 limbs) or RFO in combination with high ligation procedures (23 limbs), were analyzed retrospectively. The therapeutic effects were evaluated at 1-3 years after RFO by the improvement of clinical symptom and signs, as well as results of color Doppler ultrasonography. Results Compared with single RFO group, the obstruction rate of great saphenous vein was higher [21(91.3%) vs. 14(70.0%), χ2 =5.467, P < 0. 05], and the recanalization rate was lower [2(8.7%) vs. 8(30.0%),χ2=4.251, P<0.05] in RFO combined with high ligation group. The recurrence rate of local varicose veins was lower[0 vs. 4(20. 0%),χ2 =7. 030, P<0. 013 in RFO plos high ligation group than in single RFO group. Conclusions RFO is an effective treatment with less trauma, more safety and less scars. Combined with high ligation procedure, the effectiveness may be better.
