great arterial switch

1. Complete transposition of the great arteries, complete ventricular septum. 2. Surgery within 2-3 weeks after birth. 3. Complete aortic transposition combined with ventricular septal defect or patent ductus arteriosus can be operated within three months, at the same time repairing ventricular septal defect, ligation or suture of arterial catheter. 4. Pulmonary artery contraction surgery can also be performed first, and aortic transposition is performed 10 to 14 days later. Treatment of diseases: ventricular septal defect Indication 1. Complete transposition of the great arteries, complete ventricular septum. 2. Surgery within 2-3 weeks after birth. 3. Complete aortic transposition combined with ventricular septal defect or patent ductus arteriosus can be operated within three months, at the same time repairing ventricular septal defect, ligation or suture of arterial catheter. 4. Pulmonary artery contraction surgery can also be performed first, and aortic transposition is performed 10 to 14 days later. Preoperative preparation 1. Conventional preparation of cardiopulmonary bypass surgery. 2. Oxygen inhalation, cardiac diuretic treatment of heart failure, correction of acidosis. Surgical procedure 1. The sternal midline incision. 2. Cut the happy package to verify the diagnosis; to determine the relationship between the aorta; coronary artery opening position; with or without other malformations. 3. Establish extracorporeal circulation. 4. Separate the two major arteries, completely free the pulmonary artery, and reach the exit of the pericardium of both sides of the pulmonary artery. 5. Free the beginning of the coronary artery, and cut the opening of the two coronary arteries in a button shape. 6. The aorta is transected 1 cm above the annulus, and the pulmonary artery is severed near the bifurcation of the left and right pulmonary artery. 7. The pulmonary trunk was further separated and placed in front of the ascending aorta. The proximal end of the pulmonary artery originating from the left ventricle was anastomosed with the distal end of the ascending aorta using a 5-0 polypropylene line. 8. Make a circular incision in the root of the pulmonary artery and anastomosed the coronary artery with a 5-0 polypropylene thread. 9. Discharge the left heart, open the aorta, restore coronary blood flow, and make the distal end of the pulmonary artery and the proximal end of the ascending aorta end-to-end. 10. Repair the ascending aortic incision with a pericardial patch.
