探讨婴儿四联症手术和心肺转流技术要点及姑息手术指征，提出早期根治及必要姑息的观点。１１１例根治术在中度低温心肺转流下进行，１０例采用深低温停循环技术，４例采用低流量不停循环技术，５例处在缺氧发作状态行急症根治。另外１１例肺动脉闭锁或发育不良或冠状血管畸形者行姑息手术。本组病死率４％（５／１２５），１至２岁病死率为３．７％（４／１０９），１岁以下病死率５．８％（１／１７），５例急症手术无死亡。姑息术死亡１例，病死率９％（１／１１）。四联症在婴幼儿期根治其病死率不高于儿童期，如解剖条件许可应尽早行根治，如无根治条件也应尽早行姑息手术。四联症急症纠治术可能挽救处于缺氧持续状态的患儿。
Discuss the technical points of infantile tetralogy of Fallot and cardiopulmonary bypass and the indications of palliative surgery and put forward the view of early cure and necessary appeasement. 111 cases underwent radical hypothermia cardiopulmonary bypass, 10 cases were treated with deep hypothermic circulatory arrest, 4 cases were treated with low-flow non-stop circulation and 5 cases were treated with acute exacerbation of anoxia. Another 11 patients with pulmonary atresia or dysplasia or coronary vascular malformations were treated with palliative surgery. The case fatality rate of 4% (5/125), 1 to 2 years of age was 3.7% (4/109), 1-year-old mortality was 5.8% (1/17), 5 cases of emergency surgery without death . Palliative death in 1 case, the fatality rate was 9% (1/11). Tetralogy of Fallot in infants and young children eradicated its mortality is not higher than childhood, such as anatomical conditions should be cured as soon as possible, such as no cure should be palliative surgery as soon as possible. Quadruple disease emergency surgery may save children in a state of sustained hypoxia.
