剑鞘气管与慢性阻塞性肺疾病患者的年龄和性别相关性研究

目的：研究剑鞘气管与慢性阻塞性肺疾病（COPD）患者年龄和性别的相关性。方法：搜集2012年1-11月福建省老年医院收治的COPD患者348例,行胸部轴位CT1mm层厚连续扫描。在主动脉弓上方10min层面测量气管的内冠状径和内矢状径。剑鞘形状的程度用内冠状径与内矢状径的比率（气管指数）来表示。结果：剑鞘气管37例,均见于60岁以上气肿程度轻重不一的男性患者;气管内冠状径的长度范围在9～18mm,平均13．5mm;内矢状径的长度范围在19～32mm,平均25．5mm;气管指数的范围在0．38～0．66,平均0．52。结论：剑鞘气管与COPD患者年龄和性别密切相关,但与气肿严重程度无明显相关性。剑鞘气管的形成是由于长期慢性咳嗽所致气管软骨环的损伤、重塑型和营养不良性骨化。

The correlational research on gender and age of saber sheath trachea in patients with chronic obstructive pulmonary disease

Objective： To explore the correlation between saber-sheath trachea and COPD patient age, gender. Methods： Collection of 2012-1-1-2012-11-07 year with COPD in 348 cases, thoracic axial CI lmm layer thickness continuous scanning. In 10mm above aortic arch level measurement of tracheal intramural coronary diameter and the sagittal diameter. The shape of the level with coronary diameter and the sagit/al diameter ratio （tmch-ea index） to express. Results： Saber sheath trachea in 37 cases, were at the age above 60 emphysema degree without a male patients; endotracheal coronary diameter length range is 9-18mm, the average 13.Smm, sagittal diameter length range is 19-32mm, the average 25.5mm, tracheal index is in the range 0.38 to 0.66, average 0.52. Conclusion： Saber sheath trachea and COPD patients age, sex is closely related to, but there is no significant correlation between the severity of emphysema. Saber sheath trachea formation is due to chronic coughing caused by tracheal cartilage ring damage, remodeling and dystrophic ossification.
