Serial assessment of pulmonary artery flow by Doppler echocardiography was carried out in 15 infants after pulmonary artery banding. Three infants were identified as having branch pulmonary artery obstruction based on diastolic pulmonary artery flow. It is concluded that this flow profile may be specific for branch pulmonary artery obstruction after pulmonary artery banding.
对15例肺动脉环扎术后的婴儿进行了多普勒超声心动图对肺动脉血流的连续评估。基于舒张期肺动脉血流，3例婴儿被确定存在肺动脉分支梗阻。得出的结论是，这种血流情况可能是肺动脉环扎术后肺动脉分支梗阻所特有的。
