FIELD: medicine.
SUBSTANCE: starting from the edge of the conduit end connected to the area of pulmonary trunk bifurcation, longitudinal and transverse incisions are performed. The conduit segments obtained by the transverse incision are diverted in different directions, giving T shape to the indicated end of the conduit. A vascular 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. The conduit is directed so that the diverted conduit segments coincide with the length of the vascular incision, and the conduit is stitched in this incision.
EFFECT: method allows to adequately expand the mouths of the pulmonary arteries and prevent conduit dysfunction caused by distal stenosis in distal terms after operation.
