The purpose of this study was to evaluate the factors to development of focal pulmonary interstitial opacities adjacent to thoracic spine osteophytes among cases with right-sided aortic arch.
This was a retrospective review of our hospital information system on patients with right-sided aortic arch who underwent chest computed tomography (CT) from April 2003 to September 2014. CT were reviewed to evaluate the position and thickness of osteophytes and that of focal pulmonary opacities adjacent to osteophytes, comparing data between the patients with osteophytes with pulmonary opacity (group A) and patients with osteophytes without pulmonary opacity (group B).
There were 25 patients totally, 23 cases of left-sided thoracic osteophytes, two cases on both sides. Comparing Group A (n = 10) and Group B (n = 15), the presence of pulmonary opacities was significantly associated with thickness of osteophytes (Mann-Whitney U test, P < 0.05).
In patients with right-sided aortic arch, thoracic osteophytes were often observed on the left side. The presence of pulmonary opacities adjacent to thoracic osteophytes was associated with thickness of osteophytes. Furthermore, these interstitial opacities should not be considered a preclinical form of fibrosing lung disease.
本研究旨在评估右侧主动脉弓病例中胸椎骨赘旁局灶性肺间质混浊的发展因素。
这是一项对2003年4月至2014年9月期间接受胸部计算机断层扫描（CT）的右侧主动脉弓患者的医院信息系统进行的回顾性研究。对CT进行评估，以评估骨赘的位置和厚度以及骨赘旁局灶性肺混浊的情况，比较有肺混浊的骨赘患者（A组）和无肺混浊的骨赘患者（B组）的数据。
共有25例患者，23例左侧胸椎有骨赘，2例双侧有骨赘。比较A组（n = 10）和B组（n = 15），肺混浊的存在与骨赘厚度显著相关（曼-惠特尼U检验，P < 0.05）。
在右侧主动脉弓患者中，胸椎骨赘常出现在左侧。胸椎骨赘旁肺混浊的存在与骨赘厚度相关。此外，这些间质混浊不应被视为肺纤维化疾病的临床前期形式。
