Arterial revascularisation using in situ or Y-composite conduits of internal thoracic arteries: early results

Aim. This study aimed to research the early results of arterial revascularisation using in situ or Y-composite conduits of internal thoracic arteries. Methods. The study included 76 patients with coronary heart disease who underwent coronary artery bypass surgery between March 2018 and March 2020. Two groups of patients were selected. In the first group, autoarterial conduits from the internal thoracic arteries were used according to the in situ technique (n = 39). In the second group, autoarterial conduits were used with the formation of a Y-composite structure from the internal thoracic arteries (n = 37). Results. The general characteristics and frequency of postoperative complications for most events were comparable in both groups. The usage of on-pump coronary artery bypass graft was significantly more frequent in the in situ group than in the Y-composite group (28.2 and 3.0 %, respectively; p
