Objective：To investigate the effect of endovenous laser (EVLT) and microwave treatment (EMT) in the treatment of chronic venous insufficiency(CVI).
Methods：According to CEAP classification, patients with CVI were divided into EVLT group (102 cases) and EMT group (94 cases) randomly. The incidence of postoperative recovery, complications and the pathological changes were compared.
Results：The incidence of suggillation was higher in EVLT (25.5%) than in EMT (14.6%) group (P<0.05), but there were no significant differences in numbness, burning pain, indurated cords, relapse rate, postoperative recovery and pathological changes between the two groups (all P>0.05).
Conclusions：Both EVLT and EMT can be used to treat CVI effectively, however,  long-term results merit further investigate.
