The purpose of our study is to describe the radiologic findings of adult patients presenting with congenital unilateral pulmonary vein atresia.
Chest radiography in affected patients typically reveals a small hemithorax and ipsilateral pulmonary artery as well as ipsilateral septal thickening. CT shows, in addition, ground-glass attenuation, the absence of a pulmonary vein connection to the left atrium, and abundant mediastinal venous collateral vessels. MR imaging is helpful in further characterizing the vascular abnormalities. Angiography may help to confirm the diagnosis.
我们研究的目的是描述患有先天性单侧肺静脉闭锁的成年患者的影像学表现。
受影响患者的胸部X线检查通常显示半侧胸腔小、同侧肺动脉以及同侧间隔增厚。此外，CT显示磨玻璃样衰减、肺静脉与左心房无连接以及丰富的纵隔静脉侧支血管。磁共振成像有助于进一步明确血管异常情况。血管造影可能有助于确诊。
