摘要
目的:研究急性高原病患者胸部CT平扫影像学征象,评估胸部CT平扫检查在AHAD诊断方面的应用价值。方法:选取36例临床诊断为AHAD的患者作为观察组、18例正常进藏旅游者作为对照组,观察组中33例AMAD病例根据CAS评分划分为基本正常AMAD组、轻度AMAD组、中度AMAD组、重度AMAD组;比较观察组与对照组间主肺动脉直径(dPA)、主肺动脉与升主动脉直径比值(rPA)的差异;分析观察组胸部CT平扫影像征象。结果:观察组dPA、rPA值显著高于对照组(P<0.05);观察组3例可见肺水肿影像征象(肺内磨玻璃、云絮、斑片样密度增高影),对照组未见到肺水肿影像征象。结论:胸部CT平扫可以通过测量dPA、计算rPA值为AHAD提供客观诊断依据,通过早期发现肺水肿影像征象为确诊HAPE提供证据,胸部CT平扫在AHAD的诊断及治疗中具有重要作用。
Objective:To study the imaging features of chest CT plain scan in patients with acute high altitude disease and evaluate the application value of chest CT plain scan in the diagnosis of ahad.Methods:36 patients clinically diagnosed as AHAD were selected as the observation group and 18 normal tourists to Tibet as the control group. The 33 AMAD cases in the observation group were divided into basically normal AMAD group、mild AMAD group、 moderate AMAD group and severe AMAD group according to CAS score. The differences in the diameter of main pulmonary artery(dPA) and the ratio of main pulmonary artery to ascending aorta(rPA) between the observation group and the control group were compared. The chest CT images of the observation group were analyzed.Results:dPA and rPA values in the observation group were significantly higher than those in the control group(P<0.05). Imaging signs of pulmonary edema were observed in 3 patients in the observation group(ground glass, cloud floc and specular increased density), while no signs of pulmonary edema were observed in the control group.Conclusion:plain chest CT scan can provide objective diagnostic basis for AHAD by measuring dPA and calculating rPA value. Early detection of pulmonary edema imaging signs can provide evidence for the diagnosis of HAPE. Plain chest CT scan plays an important role in the diagnosis and treatment of AHAD.
