【摘要】：目的探讨双源CT血管成像(CT angiographye,CTA)在冠心病(coronary heart disease,CHD)合并肺部感染患者中的诊断价值。方法收集2013年1月-2014年11月CHD合并肺部感染患者65例,均经冠状动脉造影术证实为CHD且均在双源CT行冠状动脉的CTA扫描,分析冠状动脉CTA的图像质量和血管的病变。结果所有患者均出现肺部感染的临床症状;CTA图像质量达到1级的46例占70.8%、2级的有11例占16.9%、3级7例占10.8%、4级1例占1.5%;148支主要血管出现不同程度狭窄,其中轻度狭窄的有8例占12.3%,21例呈中度狭窄占32.3%,36例呈重度狭窄占55.4%;26例以钙化斑块为主占40.0%,12例以脂斑为主占18.5%,27例以混合斑块为主占41.5%;24例以右心冠状动脉状动脉作为主病变血管占36.9%,39例以前降支作为主病变血管的占60.0%,2例以左回旋支作为主病变血管占3.1%。结论肺部感染可加重CHD的症状,双源CTA可明显降低肺部感染对图像质量和诊断的影响。
[Abstract]:Objective to evaluate the diagnostic value of dual-source CT angiography (CTA) in patients with coronary heart disease (heart) complicated with pulmonary infection.Methods from January 2013 to November 2014, 65 patients with CHD complicated with pulmonary infection were studied. All patients were confirmed as CHD by coronary angiography and underwent CTA scanning of coronary artery in dual-source CT. The image quality and vascular lesion of coronary CTA were analyzed.Results the clinical symptoms of pulmonary infection were found in all patients. 46 cases (70.8%) had grade 1 of CTA images, 11 cases (16.9%) had grade 3, 7 cases (10.8%) had grade 4 of CTA, and 1 case (1 case) had 1.5 and 148 main vessels with different degrees of stenosis.Among them, 8 cases were mild stenosis (12.3%), 21 cases were moderate stenosis (32.3%), 36 cases were severe stenosis (55.4%), 26 cases were calcified plaques (40.0%), 12 cases were lipid plaques (18.5m), 27 cases were mixed plaques (41.5%), 24 cases were right coronary artery (RCAA).Pathological vessels accounted for 36.9% of 39 cases with descending branch as main lesion vessel in 60.02 cases with left circumflex branch as main lesion vessel 3.1%.Conclusion Pulmonary infection can aggravate the symptoms of CHD, and dual source CTA can significantly reduce the image quality and diagnosis of pulmonary infection.
