Sixty children in this series underwent pulmonary artery banding (PAB); isolated ventricular septal defect (VSD) was present in 24, and 20 were corrected seven months to ten years and eight months after PAB. Other anomalies were present in 37, and 15 were eventually totally corrected. Survival after PAB was 90% (95.8% with isolated VSD), and 94.3% (95% with isolated VSD) after total correction. Mean age at banding was 12.9 months, and 52.6 months at debanding. All patients underwent catheterization before PAB; 39 underwent catheterization after PAB, and ten after total correction. Pulmonary artery blood pressure was reduced from 53.5 mm Hg to 25.3 mm Hg by banding. Most patients had only moderately increased pulmonary blood flow. Banding at the altitude of Denver (1,600 m) appears to be an effective means to convert high-risk infants into lower-risk children for total correction. The cumulative mortality for two-stage treatment of VSD was 8.3%.
本系列中有60名儿童接受了肺动脉环缩术（PAB）；其中24例存在单纯室间隔缺损（VSD），20例在PAB术后7个月至10年8个月进行了矫治。37例存在其他畸形，15例最终完全矫治。PAB术后生存率为90%（单纯VSD者为95.8%），完全矫治后生存率为94.3%（单纯VSD者为95%）。环缩时的平均年龄为12.9个月，解环时为52.6个月。所有患者在PAB术前均接受了心导管检查；39例在PAB术后接受了心导管检查，10例在完全矫治后接受了心导管检查。通过环缩术，肺动脉血压从53.5 mmHg降至25.3 mmHg。大多数患者的肺血流量仅中度增加。在丹佛（海拔1600米）进行环缩术似乎是将高危婴儿转变为低风险儿童以进行完全矫治的有效方法。VSD两阶段治疗的累积死亡率为8.3%。
