Plain chest films of 87 children aged 4-14 years with valvular pulmonary stenosis proved by cardiac catheterization and of an age matched control group of 92 healthy children were evaluated in a retrospective study. Up to 4 years the evaluation was impaired by the overlying thymus. The evidence of poststenotic dilatation of the pulmonary trunk and the left pulmonary artery branch together with a normal or increased left sided perihilar pulmonary vascularity is essential for the diagnosis of valvular pulmonary stenosis. The pulmonary trunk showed marked dilatation in 47 cases, mild dilatation in 11 cases and no dilatation in 21 cases. A cranial displacement of the pulmonary trunk which partially reached or overlapped the aortic knuckle was seen in 44 children. 50 children showed a hilar enlargement due to the poststenotic dilatation of the left pulmonary artery branch. 1/5 of the children showed extension of the poststenotic enlargement into the left sided segmental artery branches. Cardiac size, calculated by heart volume, was within age specific limits. No correlation was found concerning the severity of the stenosis and the radiographic findings. Indications of valvular pulmonary stenosis increased with the age of the child.
在一项回顾性研究中，对87名年龄在4至14岁、经心导管检查证实患有瓣膜性肺动脉狭窄的儿童以及92名年龄匹配的健康儿童对照组的胸部X线平片进行了评估。4岁以下儿童的评估因胸腺重叠而受到影响。肺动脉主干和左肺动脉分支狭窄后扩张的证据，以及左侧肺门周围血管正常或增多，对于瓣膜性肺动脉狭窄的诊断至关重要。47例肺动脉主干显著扩张，11例轻度扩张，21例无扩张。44名儿童可见肺动脉主干向上移位，部分到达或重叠主动脉结。50名儿童因左肺动脉分支狭窄后扩张出现肺门增大。1/5的儿童狭窄后扩大延伸至左侧段动脉分支。按心脏体积计算的心脏大小在年龄特异性范围内。未发现狭窄严重程度与影像学表现之间存在相关性。瓣膜性肺动脉狭窄的迹象随儿童年龄增加而增多。
