摘要
目的回顾性分析老年患者腹主动脉及肠系膜上动脉(SMA)粥样硬化与缺血性肠病(IBD)的相关性。方法选取本院2010年1月—2015年12月住院期间确诊IBD的老年患者20例(IBD组)及同期住院无IBD的老年冠心病患者20例(对照组),利用Syngo.Via软件对比分析2组患者腹主动脉及SMA的CT影像学资料。结果 CT影像资料显示老年患者的钙化斑块在对照组中以点状为主,而在IBD组中以条形斑块为主,部分甚至融合为环状。IBD组中SMA的钙化斑块总数较对照组明显增多(χ~2=5.010,P=0.025),管腔狭窄更明显(Z=3.370,P=0.001)。在IBD组中,SMA病变程度与其开口狭窄程度呈正相关(r_s=0.650,P=0.002)。结论 SMA点状钙化斑块是冠心病老年人血管病变基础,大块斑块及其导致的SMA开口狭窄是引起老年人动脉粥样硬化性IBD的主要原因。
Objective To retrospectively analyze the relationship between the atherosclerosis plaques in abdominalaorta and superial mesenterial artery(SMA) and the development of ischemia bowel disease(IBD) in elderly patients.Methods Elderly patients diagnosed as IBD(n=20) and non-IBD elderly patients with coronary heart disease(n=20) wereselected in our hospital from January 2010 to December 2015. Data of CT imaging of abdominal aorta and SMA wereevaluated by Syngo.Via software in two groups. Results The calcified plaques were dominated by dots in control group,while they were the annular lesions in IBD group, according to the CT imaging data. The mean sum of calcification in SMAwas significantly increased in IBD group than that in control group(χ~2=5.010,P=0.025). The stenosis of SMA was moresignificant in IBD group compared to that of control group(Z=3.370,P=0.001). The degree of SMA lesion was positivelycorrelated with its opening stenosis in the IBD group(r_s=0.650,P=0.002). Conclusion The basic vascular lesion is dotcalcification in elderly patients with coronary heart disease, and the opening stenosis in SMA induced by mass calcificationis the main cause of atherosclerosis-induced ischemic intestinal disease in elderly people.
