Surgical repair was performed on 8 patients with tetralogy of Fallot and congenital or acquired absence of the left pulmonary artery. Prior palliative systemic-pulmonary artery shunts had been performed in the 5 patients with acquired absence of the pulmonary artery, and in none was repair of the damaged pulmonary artery possible. A valve-containing conduit (Hancock) was used in each patient to prevent pulmonary valvular regurgitation during the early postoperative period. All patients survived operation and have exhibited marked symptomatic and hemodynamic improvement. This contrasts with the poor results of corrective operation previously reported in patients in this diagnostic category. We believe that the present improved results are due in large part to the valved conduit, and we therefore recommend its use during repair in children or adults with tetralogy and a single pulmonary artery.
对8例法洛四联症合并先天性或后天性左肺动脉缺如的患者实施了外科修复手术。5例后天性肺动脉缺如的患者之前已进行过姑息性体肺分流术，且均无法修复受损的肺动脉。每位患者均使用了含瓣膜的管道（汉考克），以防止术后早期出现肺动脉瓣反流。所有患者均手术存活，症状和血流动力学均有显著改善。这与之前报道的该诊断类型患者矫正手术的不良结果形成对比。我们认为目前改善的结果很大程度上归功于带瓣管道，因此我们建议在法洛四联症合并单支肺动脉的儿童或成人修复手术中使用该管道。
