Patients with tetralogy of Fallot and unfavorable anatomy of the right ventricular outflow tract or hypoplastic pulmonary arteries may require primary palliation and subsequent repair (two-stage repair). The concept of palliation includes improvement of the lung perfusion and relief of systemic hypoxia by means of some type of arteriopulmonary arterial shunt or a Brock-type operation. At repair a previously constructed aorto-pulmonary anastomosis has to be closed, which can be done without increased risk for hospital death or postoperative morbidity.
患有法洛四联症且右心室流出道解剖结构不佳或肺动脉发育不全的患者可能需要进行一期姑息治疗及后续修复（两阶段修复）。姑息治疗的概念包括通过某种类型的体肺分流术或布罗克式手术改善肺灌注并缓解全身缺氧。在修复手术时，先前构建的主肺动脉吻合口必须关闭，这样做不会增加医院死亡风险或术后发病率。
