EFFICACY ANALYSIS OF MODIFIED FIBERIN ENDOVENOUS LASER ABLATION
The aim of the study is to improve the results of endovenous laser ablation by increasing the laser exposure and eliminating carbonization and burning of the ber to the vein. Material and methods. Fiftynine patients with varicose veins of the lower extremities in the saphenous vein system have been randomly divided into two equal groups. One group underwent endovenous laser ablation with a Biolitec radial ber, and the other group underwent endovenous laser ablation with a modied cylindrical ber. The number of burnings of the ber to the vein is estimated intraoperatively. In the postoperative period, ablation of the veins is evaluated at the rst, 14th, 60th and 180th day, and the severity of pain during the rst 14 days. Results fter endovenous laser ablation, regardless of the type of ber, complete ablation of all investigated veins is revealed in each observation period. The severity of pain after endovenous laser ablation with a modied ber is statistically signicantly lower at all periods of observation (p < 0.05). With endovenous laser ablation, the burning of the ber to the vein is completely absent (p < 0.05).
