Radioisotope lung scanning was used to investigate the distribution of pulmonary blood flow after banding of the pulmonary artery in children with a left-to-right shunt and pulmonary hypertension. An abnormal distribution of blood flow in the lung on the side of the operation approach was observed in all patients in the first three weeks following surgery. Abnormalities were still observed in 17 of 21 children 10 months to more than 8 years after the banding operation. There was no significant relation between the occurrence of these abnormalities and time after surgery. Diminished flow to the zones of the right lung was observed less frequently. The incidence of abnormalities in flow distribution was also high preoperatively. Respiratory complications in infants with large left-to-right shunts were considered to be responsible for most of the abnormal blood flow distributions observed. Radioactive lung scanning was found to be a valuable diagnostic method in the early and late postoperative period in infants and small children. It was more sensitive than the other techniques used in revealing deviation of blood flow from one lung in those cases with shifting of the applied band.
放射性同位素肺扫描用于研究左向右分流合并肺动脉高压患儿肺动脉束带术后肺血流分布情况。术后前三周，所有患者手术侧肺血流分布均异常。束带手术后10个月至8年以上，21例患儿中有17例仍存在异常。这些异常的发生与术后时间无显著关系。右肺区域血流减少较少见。术前血流分布异常发生率也较高。左向右分流量大的婴儿发生的呼吸并发症被认为是观察到的大多数异常血流分布的原因。放射性肺扫描被发现是婴幼儿术后早期和晚期有价值的诊断方法。在应用束带移位的病例中，它比其他技术更能敏感地显示一侧肺血流的偏差。
