摘要
目的 :分析缩窄性心包炎螺旋CT表现特点 ,评价螺旋CT诊断价值。方法 :对 31例手术病理证实的缩窄性心包炎患者进行螺旋CT检查 ,分析其CT表现特点并和手术发现对比。结果 :CT诊断正确率为 96 8%(30 /31)。 30例发现心包增厚 ,最大厚度为 3～ 2 4mm (6± 2 6mm) ,和术中心包厚度测量一致性较高 (P <0 0 5 )。CT显示心包钙化 17例 ,漏诊 3例。心室腔缩小、变形 15例 ,室间隔扭曲 4例。心包钙化组血流动力学异常征象出现率显著高于非钙化组 (P <0 0 5 )。结论 :螺旋CT能准确显示缩窄性心包炎的各种病理改变 ,是诊断缩窄性心包炎的可靠手段之一。
Objective： To study the helical CT features of constrictive pericarditis and evaluate the diagnostic importance of helical CT. Materials and methods： 31 cases of constrictive periarditis proved by operation underwent helical CT scan. the CT features were analyzed and compared with uperation findings. Results： The correct rate of CT diagnosis was 96,8% （30/31）. Pericardial thickening was found in 30 cases, the thickness measured on CT was 3 - 24mm （6 ± 2,6） and was eonsistent well with that of measured in nperation （P 〈 0.05）, 17 of 20 cases pericardial calcification was found on CT. The ventricle cavities were smaller in 15 cases, the ventricular septum distortion in 4 cases. The rate of abnomml blood dynamic signs in pericardial calcification group was much higher then that of non - calcification group （ P 〈 0.05 ） o Conclusion： Helical CT is very reliable in displaying the various pathological changes of constrictive pericarditis, and valuable in the diagnosis of constrictive pericarditis.
