The results on the in-stent restenosis in the mid-term period after successful coronary arteries chronic total occlusion (CTO) recanalization by the antegrade approach are assessed. The study included 117 patients who underwent coronary artery CTO recanalization for the period from 2009 to 2012. After 6.1 ± 0.9 months (stage К1) and 12.7 ± 1.6 months (stage К2), all patients were examined by coronary angiography, intravascular ultrasound and optical coherence tomography. During the frst half of the year after the CTO recanalization, there was a more frequent in-stent restenosis rate in the right coronary artery (in 25.6 %) as well as a predominance of focal types of restenosis (59.1 % of the total). The incidence of restenosis depending on the DES type varied over a wide range of values (from 0 to 52.4 % in the frst half of the year and from 0 to 41.2 % in the second half of the year). A signifcant increase in the incidence of restenosis was observed after the trapidil eluting stents implantation (52.4 % in the frst half of the year, 26.3 % in the second half of the year) and sirolimus eluting stents (38.9 % in the frst half, 41.2 % in the second half of the year). Our data show that different types of DES differently determine the changes in the vascular lumen during the medium term period after the successful CTO recanalization.
