total vena cava and pulmonary artery connection

1. Tricuspid occlusion. 2. Severe Ebstan malformation. 3. Single ventricle. All of the above must have normal pulmonary vascular resistance. Preoperative preparation: 1. Cardiopulmonary bypass surgery routine preparation. 2. Oxygen inhalation, with hypoxic hair, the authors take propranolol (property) and other drugs. Postoperative intravenous infusion of sodium nitroprusside, dopamine or dobutamine to enhance myocardial contractility, reduce afterload, and prevent low cardiac output syndrome. Treatment of diseases: tricuspid atresia single ventricle Indication 1. Tricuspid occlusion. 2. Severe Ebstan malformation. 3. Single ventricle. All of the above must have normal pulmonary vascular resistance. 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. The chest midline incision. 2. Cut the happy package to verify the diagnosis. 3. Establish extracorporeal circulation. The superior vena cava cannula was inserted above the azygous vein with a right angle cannula. 4. Free pulmonary trunk and bilateral pulmonary arteries until their pericardial exit. 5. Make a right atrium "]" incision. 6. Excision of part of the interatrial septum, so that the atrial septal defect is expanded to about 2.5cm. 7. The atrial wall is sutured around the superior and inferior vena cava openings to form a tube. 8. Suture the left edge of the right atrial incision in the right atrial wall near the room ditch, or add a patch to enlarge the heart chamber. 9. The distal end of the superior vena cava was cut and the end of the right pulmonary artery was anastomosed. 10. Cut off the root of the pulmonary artery and close the proximal end of the heart. The proximal end of the superior vena cava is anastomosed to the pulmonary artery. 11. Expanded polytetrafluoroethylene artificial blood vessels can also be used as an atrial tunnel in the inferior vena cava of the atrium to the proximal segment of the superior vena cava.
