64层螺旋CT在冠心病患者肠系膜动脉狭窄诊断中的价值

Evaluation of Application of 64 Multi-slice CT in Diagnosing Mesenteric Arterial Stenosis in Patients with Coronary Artery Disease

目的:探讨64层螺旋CT血管造影在诊断冠心病患者肠系膜动脉狭窄中的价值。方法:收集临床行64层螺旋CT血管造影或数字减影血管造影术已确诊的冠状动脉狭窄的患者1080例,轻、中、重度狭窄各360例(分别编为A、B、C组),进行64层螺旋CT肠系膜动脉血管造影检查,判断冠状动脉狭窄程度与肠系膜狭窄是否存在相关性。结果:A、B、C三组之间均存在统计学差异,C组肠系膜狭窄的风险程度明显高于A、B两组。结论:64层螺旋CT能够清晰显示肠系膜动脉狭窄,并能准确预测冠心病患者肠系膜动脉狭窄的风险。

Objective：To explore the clinical significance of 64 multi-slice CT （MSCT） in diagnosing mesenteric arterial stenosis （MAS） in patients with coronary artery disease. Methods：One thousand and eighty patients who were clinically diagnosed as coronary arterial stenosis （CAS） by 64 multi-slice CT angiography （64MSCTA） or doppler spectrum analysis （DSA） were divided into three groups：mild,moderate,and severe groups （groups A,B,and C） according to the severity of CAS with 360 in each group. Mesenteric artery of the patients were examined with 64MSCTA,and the relationship between the severity of CAS and MAS was analyzed. Results：There were statistically significant differences among groups A,B and C,and the risk of MAS in group C was obviously higher than those of groups A and B. Conclusion：64 MSCT provides clear images of MAS and can predict the risk of MAS in patients with CAS.
