Twenty-four of 230 patients with patent ductus arteriosus had hypovascularity and hyperlucency in the left lung on preoperative chest roentgenograms. Two of the 24 patients died shortly after operation, and one was unavailable for follow-up. During the postoperative course (mean, three years), roentgenograms of eight of the remaining 21 patients showed persistent, unequal pulmonary vascularity and hyperlucent left lung, with no evidence of air trapping, and two patients had diminished volume of the hyperlucent left lung compared with that of the right lung.
230例动脉导管未闭患者中，24例术前胸部X线片显示左肺血管减少和透亮度增加。这24例患者中有2例术后不久死亡，1例失访。在术后过程中（平均3年），其余21例患者中的8例X线片显示持续的、不等的肺血管分布及左肺透亮度增加，无空气潴留证据，2例患者左肺透亮度增加区域与右肺相比体积减小。
