扁胸综合症的临床和X线分析

目的：探讨X线表现在扁胸综合症的临床应用价值。方法：回顾分析25例扁胸综合症的X线的影像学资料,并加以总结。结果：全部病例摄取标准胸部正侧位片,测量胸廓前后径（APDb）和横径（TTDb）,计算胸前后径和横径之比率。APDb/TTDb比值≤38%可诊断直背综合征。按照分级标准,本组25例,轻度（38～36%）14例;中度（35～33%）10例和重度（32%以下）1例。结论：X线影像学表现在扁胸综合症的诊断上具有较高的临床价值。

Clinical Manifestation and X- ray Sign in Flat Thorax Syndrome

Objective：To assess the clinical application of X-ray sign in flat thorax syndrome.Methods：X-ray sign in patients with flat thorax syndrome in 25 patients were analyzed summarized.Results：The standard P-A and lateral chest film were taken,the antero-posterior（APDb）,transthoracic diameter（TTDb） of the thorax were measured and the ratio of APDb to TTDb was calculated.The flat thorax syndrome could be diagnosed with the ratio of APDb/TTDb of the thorax ≤38%.According to the classification standards,Of all patients,the ratio of 14 patients were mild（38～36%）,the ratio of 10 patients were moderate（35～33%）;the ratio of 1 patients were major（〈32%）.Conclusions：X-ray sign in the diagnosis of flat thorax syndrome have a high clinical value.
