Abstract

AIM. Evaluation of the effectiveness of intraoperative ultrasound flowmetry and identification of differences
in blood flow characteristics by autoarterial shunts in patients with high surgical risk (EvroScore>6) who
underwent surgery in IC conditions and on a working heart.
Material and methods. The analysis included 96 patients with high surgical risk who underwent CABG both in
the of on pump and on a working heart conditions. The average age of patients in groups 1 and 2 was 61.5±2.9
and 62.4±3.0 years, respectively (p=0.5). All patients of both groups underwent intraoperative ultrasound
flowmetry.
Results. The indicators of intraoperative flowmetry confirm the good functioning of autoarterial transplants:
the average volume blood flow rate is more than 20 ml/min, the pulsation index is not higher than 5 units and
the diastolic filling is higher than 50%. Previously used methods do not allow us to estimate the speed of blood
flow, to give a quantitative, devoid of subjectivity, assessment of blood flow. Flowmetry is the most commonly
used method for assessing the quality of shunts and can detect 2-4% of shunts that require revision.
