FIELD: medicine.
SUBSTANCE: starting from the edge of the conduit end connected to the pulmonary bifurcation area, a longitudinal section is made along the conduit and then a transverse section, the length of the cross section corresponding to half the length of the conduit circle, the cross-sectional segments of the conduit being bent in different directions, giving the indicated end of the conduit a T-shape. An incision is performed through the area of pulmonary trunk bifurcation with a transition to the right and left pulmonary arteries to the mouths of their lobar branches on each side. The conduit is directed so that the diverted conduit segments - the flat part of "T" - coincide with the length of the vascular incision, and the conduit is stitched in this incision.
EFFECT: method prevents conduit dysfunction in the development of distal stenosis in the long-term postoperative period due to the absence of a two-dimensional circular closure of the anastomosis line, allows to manipulate the angle of conduit junction with pulmonary bifurcation in order to minimize bending of its outflow segment, depending on the choice of the location of the vascular incision on pulmonary arteries, provides reduced traumatic intervention by eliminating additional incisions on the pulmonary trunk due to the use of original equipment for draining conduit segment formation.
