[Possibilities of using the Colibri system for endovenous laser ablation]

The purpose of the study was to assess efficacy of endovenous laser ablation of major saphenous veins by means of the Mediola single-ring radial light guides with the use of the 'Optical Handpiece MHP02 (Colibri)'.

This non-comparative prospective study included 430 consecutive patients who underwent a total of 511 endovenous laser ablation procedures from January 2018 to March 2019. The great saphenous vein was subjected to obliteration in 343 (67.1%) cases, the anterior accessory saphenous vein - in 94 (18.4%) cases, and the small saphenous vein - in 74 (14.5%) cases. There were 170 (39.5%) men and 260 (60.5%) women, with a mean age of 52±12.8 years.

The next day after the intervention the patients revisited the clinic for control examination, with the obtained findings demonstrating that occlusion of the target vein had been achieved in all 511 (100%) cases. At 2 months, we examined 411 (95.6%) people with a total of 484 (94.7%) treated veins. After 6 months, 399 (92.8%) people with 472 (92.4%) veins were examined. Recanalization with pathological reflux during the entire follow-up period was registered in 6 (1.3%) cases. Hence, the long-term rate of obliteration amounted to 98.7%.

1) endovenous laser ablation of major saphenous veins by means of the Mediola laser unit with wavelength of 1470 nm and single-ring radial light guides with the use of the 'Optical Handpiece MHP02 (Colibri)' made it possible to achieve obliteration of the target vein in 98.7% of cases at 6 months of follow up; 2) within the mentioned terms, the need for repeat intervention could appear in 1.1% of cases; 3) the Colibri system provides a possibility of decreasing the final cost of radial light guides for endovenous laser ablation by 30-50%.
