THE RESULTS OF AN AIMED INCOMPLETE MYOCARDIAL REVASCULARIZATION WITH LOW INVASIVE AND STANDARD TECHNICS OF CORONARY BYPASS

Aim. Comparison of in-hospital results of two strategies on an aimed incomplete myocardial revascularization (AIMR) ONCAB and MIDCAB of left anterior descending artery (LAD) in multivessel coronary disease patients.

Material and methods. To the study, 63 patients included with achieved AIMR (LAD shunting) in multivessel disease. All patients, depending on the strategy of revascularization, were selected to 2 groups: 1. ONCAB (47,6%, n=30) and 2. MIDCAB (52,4%, n=33).

Results. In the early post-surgery period of follow-up, among the adverse cardiovascular events, in the general selection of patients, there was non-fatal Q-myocardial infarction in MIDCAB group, followed by a decline of the left ventricle ejection fraction from 65% to 38%. ONCAB group was characterized by higher volume intra-operational blood loss, rate of wound and hemorrhagic complications, that in one case led to remediastinotomy, and in every tenth patient — blood transfusion during the early period. In our study, the chosen surgical strategy was the only alternative to medication therapy.

Conclusion. In the study, at in-hospital stage of management there were comparable outcomes of AIMR with either ONCAB and MIDCAB. Nevertheless, coronary bypass with MIDCAB technology demonstrated a range of benefits related to decreased risk of hemorrhagic complications, wound infection and lower duration of hospitalization.
