目的探讨CT肺血管成像(CTpulmonaryangiography,CTPA)在白塞氏综合征肺部损害诊断中的临床应用价值。方法应用GE公司LightSpeedPlus4型CT机,对17例白塞氏综合征进行常规肺扫描及肺血管成像,分析2种影像资料的表现,并加以比较与综合。对比分析采用χ2检验。结果常规CT主要表现:17例均有双肺或一侧肺密度不均,9例肺动脉有单发或多发且程度不一的瘤样扩张,12例可见肺血管增粗,6例见管壁不规则及狭窄,5例见有节段性浸润灶。CTPA表现为:17例中,15例见肺动脉瘤形成、且6例动脉瘤内见血栓形成,16例肺动脉扩张,15例肺动脉管壁不光滑、管腔不规则,8例有多发肺动脉血栓形成。动脉瘤、肺动脉管壁管腔改变及肺动脉扩张的χ2值分别是5.10、10.08、3.24,P值分别<0.05、<0.05、>0.05。结论综合临床、常规CT及CTPA可提示白塞氏综合征肺部损害的诊断。
Objective To investigate the clinical value of CT pulmonary angiography (CTPA) in the diagnosis of Behcet’s syndrome lung damage. Methods GE company LightSpeedPlus4 CT machine, 17 cases of Behcet’s syndrome were routine lung scans and pulmonary vascular imaging, analysis of two kinds of imaging data performance, and to be compared and integrated. Comparative analysis using χ2 test. Results The results of routine CT showed that all 17 cases had uneven lung density on one or both sides of the lung, 9 cases of single or multiple pulmonary embolism with varying degrees of tumor-like dilation, 12 cases of pulmonary vascular thickening, 6 cases of wall Irregular and narrow, 5 cases, see a section of infiltration stove. CTPA showed: 17 cases, 15 cases of pulmonary aneurysm formation, and 6 cases of thrombosis within the aneurysm, 16 cases of pulmonary artery dilatation, 15 cases of pulmonary artery wall is not smooth, irregular lumen, 8 cases of multiple pulmonary thrombosis . The χ2 values of aneurysm, pulmonary artery wall lumen and pulmonary artery dilatation were 5.10,10.08,3.24, P <0.05, <0.05,> 0.05 respectively. Conclusion The comprehensive clinical, routine CT and CTPA can prompt the diagnosis of Behcet’s syndrome lung damage.
