Single ventricle Treatment
Palliative operation: Increase the (body and pulmonary artery bypass surgery) or decrease (banding of pulmonary artery) pulmonary blood flow to improve Single ventricle symptoms. However, palliative surgery has its disadvantages, such as the body - pulmonary shunt after pulmonary artery often distorted, so that in future, when Correction difficult operation; pulmonary blood flow will increase too much capacity because of increased ventricular load and lead to heart failure; the superior vena cava - pulmonary artery anastomosis (Glenn operation) does not increase ventricular volume load, but sometimes occur late ipsilateral pulmonary vein fistula; pulmonary band shift to the distal pulmonary artery can cause distortions. Palliative surgery for the treatment of the effects of single ventricle and found that either increase or decrease for blood flow and lung surgery, 30% of A and 75% of C-type single ventricle have died after 10 years in diagnosis, so palliative surgery is useful but inadequate.
Ventricular exclusion operation: The pulmonary circulation directly from the atrium and ventricle into the pulmonary artery (the side seam of the atrioventricular valve closure and pulmonary root holes), and left single ventricle for systemic use. Between ventricular and aortic blood flow from the passages are narrow, Ventricular exclusion operation have higher risk.
Separate ventricular surgery: a large man-made fiber fabrics, will be separated from ventricular cavity for a second, to accept the side of the atrioventricular valve of the blood, and the supply of pulmonary artery and aorta, respectively. Although complex and difficult operation by the operation of the continuous improvement of technology, but the effect is still not satisfactory. Separate ventricular surgery should be restricted to the left forward position with the aortic valve output chamber (A-Ⅲ type), and normal atrioventricular valve, ventricular output Non-blocking lesions, not previously palliative surgery, preoperative non-congestive heart failure and cyanosis.
