Objective. To compare the rate of neurologic complications in infants with aortic coarctation and aortic arch hypoplasia undergoing aortic arch repair under deep hypothermic circulatory arrest or full-flow perfusion with double arterial cannulation. Material and methods. This pilot single-center simple blinded prospective study assessed the early postoperative outcomes in infants with aortic arch obstruction. Patients underwent on-pump repair under deep hypothermic circulatory arrest (I group, 20 pa-tients) or full-flow perfusion with double arterial cannulation (II group, 20 patients). Results. In-hospital mortality was 5% (1 patient) in each group (p>0.05). Neurologic complications occurred in 14 (70%) patients of the 1st group and 6 patients (30%) of the 2nd group (p=0.025). The only significant risk factor was head tissue saturation accord-ing to near-infrared spectroscopy. Each percent decreased the risk of neurologic event by 6%. Conclusion. Aortic arch repair under full-flow perfusion reduces the rate of neurologic events in infants compared to deep hypo-thermic circulatory arrest. Head tissue saturation was the risk factor of neurologic complications. Each percent decreased the risk of neurologic event by 6%.
