Immediate Angiographic Results in Patients with Chronic Coronary Occlusion

Aksenov E. V., Golovenko V. B., Gumenyuk B. M.

The work deals with the study of direct angiographic results during endovascular recanalization in patients with chronic coronary occlusion (CCO). Material and methods. The research included 365 patients with CCO, who were conducted diagnostic and medical intervention procedures for this pathology on the basis of the angiographic department National Institute of N. Amosov Cardiovascular Surgery. The average age of patients was 66,96±1,81, the average weight was 86,5±1,44 kg. Duration of occlusion was determined from the moment of myocardial infarction in the basin of the infarct-linked coronary artery (CA). Results and discussion. The duration of occlusion from 3 to 6 months was observed in 26.8% of patients (98 patients). The period of occlusion from 6 to 12 months was registered in 37.5% of patients (137 people). The total duration of occlusion from 1 year to 3 years was in 35.6% of patients (130 patients). As a result of the performed studies, it was determined that in patients who had CCO during 1 year up to 3 years, the negative angiographic result was 2.2 times more than in patients with a period of occlusion up to 1 year (р = 0,001256). In assessing the effect of the "prescription" of obstruction CА on the immediate results of diffraction of patients with CCO, we found out that in the first year after the occurrence of occlusion, the probability of successful recovery of coronary blood flow is the highest. Conclusions. During operation of recanalization in patients with CCO, the highest percentage of angiographic success was achieved when the right coronary artery was recanalized (89.6% of cases), and the highest percentage of procedural failures was observed in the recanalization of the right descending artery (17.5% of cases).
