Background: Endovenous thermal techniques, such as endovenous laser ablation (EVLA), are the recommended treatment for varicose veins. Non-thermal techniques such as mechanochemical ablation (MOCA) have potential benefits.Aim of the work: To compare EVLA with MOCA in the treatment of primary varicose vein of the lower limb.Patients and Methods: 40 patients who had primary great saphenous VV admitted at the vascular surgery department, Al-Azhar university hospital, New Damietta, Egypt. They randomized into two equal groups each one was 20 patients group-1 treated by EVLA and group 2 treated by MOCA.Results: The time of operation of studied patients ranged from 22 to 44 minutes, and there a statistically significant decrease in time of group 2 when compared to group 1. (25.36±1.80 vs. 37.30±2.47 respectively). Postoperative pain in studied patients ranged from 0 (no pain) to 7 (severe pain), there statistically significant decrease in pain of group 2 when compared to group 1. As regard to induration, it was reported in 4 patients, representing 20% of group 1 (4) patients, were significant differences between groups 1 and 2 (20% vs. 0% respectively). At the end of the sixth month postoperatively, as regard complete occlusion of the GSV vein, there was statistically no significant difference between group 2 when compared to group 1 (92.5% vs. 95% respectively).Conclusions: MOCA was associated with better results on short-term follow-up.
