RESUMEN
Objective To compare the clinical results of endovenous laser treatment(EVLT),radiofrequency endovenous occlusion(RFO)and conventional stripping combined with transilluminated powered phlebectomy(TIPP)for lower extremity varicose vein.Methods From Jun 2004 to Jan 2007,200 cases(232 limbs)were treated by EVLT with TIPP,80 cases(88 limbs)by RFO with TIPP,and 180 cases(202 limbs)by conventional stripping with TIPP.Operation time,number of the incision made,intraoperative bleeding,postoperative hospital stay,complications,and one-year recurrence rate were compared with each other. Results Operation time was longer(41±8)min in RFO group than that in other two groups.Postoperative hospital stay was shorter in EVLT group(1.2±0.4 d)and RFO group (2.1±0.8 d)than that in stripping and TIPP group(P＜0.05).Patients in stripping group also suffered from more intra-operative bleeding more often incidental nervus saphenus injury and more incision numbers when compared with other two groups(P＜0.05).There was no significant difierence in one-year recurrence rate among patients in the three groups. Conclusions The clinical efficacy is almost the same among the three groups in terms of eradication of the varicose veins.EVLT and RFO are safe and minimal invasive for the treatment of lower extremity varicose vein.
