Modified Fontan procedure

1. Tricuspid occlusion. 2. Severe Ebstan malformation. 3. Single ventricle. All of the above must have normal pulmonary vascular resistance. Treatment of diseases: tricuspid atresia tricuspid atresia Indication 1. Tricuspid occlusion. 2. Severe Ebstan malformation. 3. Single ventricle. All of the above must have normal pulmonary vascular resistance. Contraindications Preoperative preparation 1. Conventional preparation of cardiopulmonary bypass surgery. 2. Oxygen inhalation, with hypoxic hair, the authors take propranolol (property) and other drugs. Surgical procedure (1) Connection between right atrium and right ventricle 1. The sternal midline incision. 2. Cut the happy package to verify the diagnosis. 3. When establishing extracorporeal circulation, the superior vena cava cannula should be inserted from the proximal segment of the superior vena cava. 4. Make a "[" and "]" incision in the left atrial appendage and the right ventricle. 5. Repair atrial septal defect and ventricular septal defect. 6. The left edge of the right atrial appendage incision and the right edge of the right ventricular funnel incision were sutured together with a 5-0 polypropylene thread. 7. Cover the right atrial appendage and the funnel incision with a pericardial patch or pre-coagulated polyester vascular sheet, and suture the pericardial or polyester vascular sheet to the edge of the heart incision with continuous suture. (B) right atrial and pulmonary artery connection 1. The sternal midline incision. 2. Cut the happy package to verify the diagnosis. 3. When establishing extracorporeal circulation, the superior vena cava cannula should be inserted from the proximal segment of the superior vena cava. 4. The right atrial incision was used to repair the atrial septal defect, and the pulmonary valve was sutured through the pulmonary artery incision. 5. The right atrial incision was anastomosed to the pulmonary artery incision, the posterior margin was sutured continuously, and the leading edge was intermittently stiff. 6. It is also possible to use the artificial blood vessel slice in front of the right atrial appendage after the distal edge of the pulmonary artery trunk.
