COMPARATIVE ANALYSIS OF THE RESULTS OF THE MECHANOCHEMICAL ENDOVENOUS ABLATION OF GREAT SAPHENOUS VEIN USING POLYDOCANOL FOAM OF ROOM TEMPERATURE AND COOLED ONE

Objective. To conduct a comparative analysis of long-term (3-yars) results of varicose veins treatment by mechanochemical endovenous ablation (MOCA) with using polidocanol foam of room temperature and a chilled one. Methods. The study is based on the treatment results of 122 patients with great saphenous vein (GSV) incompetence. The patients were randomized into 2 groups. In the main group (n=60), mechano-chemical ablation was performed according to original technique, using a cooled sclerosant, 60ᵒ degrees leg elevation and a shin bandage; in the comparison group (n=62) standard technique was used. The median GSV diameter in the main group was Me (Q25; Q75) = 7.4 (5.8; 8.2) mm, in the comparison group - Me (Q25; Q75) = 7.3 (5.6; 8.3) mm (P=0.794). Results. One month after the surgery, the GSV was totally occluded in 100% cases in the main and in 96.7% cases in the comparison group (P=0.496). One year after the surgery, occlusion rates were 94.6% and 80.4% respectively (P=0.042). 3 years later, GSV occlusion was diagnosed in 92.6% cases and in 76.4% cases, respectively (P=0.0033). Hyperpigmentation was reported in 21.7% legs in the main group and 22.6% legs in the comparison group (P>0,99). Transient superficial phlebitis developed in 6.7% and in 8.1% legs, respectively (P=0.744). Conclusion. Endovenous mechanochemical cryoablation is more effective than the standard MOCA technique and can be considered as the most preferable method for eliminating reflux in the GSV. What this paper adds A comparative safety and efficacy of the endovenous mechanochemical cryoablation in comparison with the standard technique to eliminate GSV reflux has been evaluated for the first time. A small number of complications and significant positive dynamics of clinical symptoms were reported in both groups. After 3 years, GSV recanalization rate was 3.2 times higher using the standard technique.
