Occult pulmonary artery is an uncommon cardiovascular defect. Associated symptoms include recurrent pulmonary infections and congestive heart failure. The authors describe a one-year-old boy initially diagnosed as having broncho-pulmonary dysplasia who developed severe failure to thrive, recurrent pneumonias, and pulmonary hypertension. The presence of an occult right pulmonary artery was suspected by lung perfusion scan and diagnosed by cardiac catheterization and angiography. After surgical repair, his clinical course improved and his growth and development were normal. This case demonstrates the importance of including occult pulmonary artery in the differential diagnosis of infants with failure to thrive associated with recurrent pulmonary infection.
隐匿性肺动脉是一种罕见的心血管缺陷。相关症状包括反复肺部感染和充血性心力衰竭。作者描述了一名一岁男孩，最初被诊断为支气管肺发育不良，后来出现严重的生长发育迟缓、反复肺炎和肺动脉高压。通过肺灌注扫描怀疑存在隐匿性右肺动脉，并通过心导管检查和血管造影确诊。手术修复后，他的临床病程得到改善，生长发育正常。该病例表明，在对伴有反复肺部感染的生长发育迟缓婴儿进行鉴别诊断时，应考虑隐匿性肺动脉。
