This is a study of 23 cases with pulmonary plethora and cardiac failure. A "banding" of pulmonary artery was performed, to diminish the pulmonary bloodflow in order to avoid the development of pulmonary hypertensive changes and to improve the heart failure. The mean age of the cases operated upon was 16,9 months. The complications post-banding were: stenosis of the pulmonary outflow tract and necrosis or calcification of the pulmonary artery wall. There was a direct relationship between these complications and the time of persistence of the "banding". The pulmonary artery pressure, distal to the "banding", was reduced as much as 2/3 of the previous pressure in all patients below 6 months and in 63,64% of those patients above 1 year old. A patent ductus arteriosus, complicating the ventricular septal defectis closed prior to perform the "banding" in order to see its role in the pulmonary hyperkinetic hypertension. This is carried out only if pulmonary hypertension remains unaffected.
这是一项针对23例肺充血和心力衰竭病例的研究。进行了肺动脉“束带术”，以减少肺血流量，从而避免肺高压变化的发展并改善心力衰竭。接受手术的病例的平均年龄为16.9个月。束带术后的并发症有：肺流出道狭窄以及肺动脉壁坏死或钙化。这些并发症与“束带”持续时间之间存在直接关系。在所有6个月以下的患者以及63.64%的1岁以上患者中，“束带”远端的肺动脉压力降低至先前压力的2/3。为了观察动脉导管未闭在肺高动力性高血压中的作用，在进行“束带术”之前，先关闭并发室间隔缺损的动脉导管未闭。仅当肺动脉高压未受影响时才进行此操作。
