Puncture miniinvasive methods of surgical treatment of primary varicoses of the superficial veins of the lower extremities c2-c6s

Abstract. Treatment results of primary varicose disorders has been shown in article. The experience of using of thermal (endovenous laser ablation, radiofrequency ablation) and non-thermal methods (endovenous mechanochemical ablation, echo-controlled introduction of bioglue) in treatment of stage C2-С6 chronic venous is shown. The purpose of this work is to evaluate the efficiency of endovenous ablation techniques. The treatment of 218 patients was analyzed. In the group of patients who underwent EVLA, reflux was detected in 2 cases at the follow-up after week. In our opinion, this is due to insufficient exposure of the laser irradiation using a single-ring type of light guide. To correct the detected reflux, a single injection of foam scleroterapy. Foam form (3%) was used. In the group of patients after RFA, inflow reflux was detected in 1 patient (5.2%), in other cases complete obliteration was observed (17 patients - 89.4%). In the group of patients with mechanochemical obliteration, recanalization was determined in 5 patients (19.2%) with control ultrasound after 1 month. It was corrected by carrying out the procedure of foam scleroobliteration. In the group of patients with the cyanoacrylate obliteration, inflow reflux was detected in 2 patients (14.2%) on examination after 1 month. The received results lead to conclusion, that endovenous laser coagulation of affected veins is a more reliable method of threatment and the gold standard. The advantage of non-thermal methods is the absence of thermal effects on the paravenous structures, respectively, patients have no pain during the procedure, increases comfort, and there is no risk of damage to the paravenous nerves. Another advantage of non-thermal techniques is no need to use of tumescent anesthesia, since only one puncture is required for the operation, which is comfortable for patients. The use of adhesive vein obliteration is justified in patients with signs of a short reflux duration and has an advantage for the patient due to the absence of the need for compression in the postoperative period. In our study, foam sclerotherapy was the method of choice for treatment correction, if necessary.
