METHOD FOR SURGICAL TREATMENT OF CONGENITAL AORTA ARCH BREAK IN INFANTS AND NEWBORNS Russian patent published in 2022 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to cardiac surgery. A median sternotomy access is performed with exposure of the arch with branches and the descending aorta beyond the region of the aortic arch interruption. Artificial circulation is connected with separate perfusion of the upper and lower parts of the patient's body. Cardioplegia is performed, cutting off the pulmonary trunk from the arterial duct and closing the hole in the wall of the pulmonary artery bifurcation, cutting off the bifurcation below the orifices of the branches of the pulmonary artery, transversely crossing the pulmonary trunk above the valvular commissures and removing it as a native autograft having the shape of a cylinder truncated on both sides with an angle of planes around 30°. Then direct anastomosis of the root of the pulmonary trunk with bifurcation is carried out. The aortic arch is opened along the internal curvature to the upper third of the ascending aorta. The ductal tissue is dissected from the clamped descending aorta. The lung autograft is positioned with its shorter wall cranially and the larger wall caudally. Two fistulas are formed with a continuous twisting suture - the descending aorta with the distal end of the autograft and the ascending aorta and the arch with the proximal end. Perfusion of the body is resumed and air is expelled upon completion of the reconstruction of the arch and the sternum is sutured.

EFFECT: method allows to reduce the risk of aneurysms, calcification or restenosis of the aortic arch section being reconstructed due to the achievement of normal biventricular hemodynamics.
