64排螺旋CT在急诊胸闷伴2型糖尿病患者中的应用研究

Clinical application of 64-slices spiral CT in angiography of coronary artery in type 2 diabetics with tightness in chest in emergency department

目的:探讨64层螺旋CT(MSCT)冠状动脉造影在急诊2型糖尿病伴胸闷患者临床应用价值。方法:对40例急诊胸闷伴2型糖尿病患者行64层MSCT冠脉造影检查,利用其先进的后处理功能对冠脉进行重组,以显示冠脉各主支及分支,并对冠脉病变进行诊断。结果:40例行64层MSCT冠脉造影均成功显示冠脉各主支(左冠脉主支、左冠脉回旋支、左冠脉前降支及右冠脉主支)及其分支(包括右冠脉的后降支、左室后支、圆锥支、窦房结动脉及左冠脉的对角支、钝缘支等),30例患者的52支冠脉有不同程度的硬斑块和软斑块,其中26例的40支冠脉伴有不同程度的狭窄,26例病员同时行选择性血管造影的患者显示38支冠脉有不同程度的狭窄。结论:64层MSCT是一种安全可靠的检查方法,在急诊2型糖尿病伴胸闷患者中具有广阔的应用前景。

Objective： To study the clinical application of 64 - slices spiral CT in coronary artery in type 2 diabetics with tightness inthe chest in emergency department. Methods： 40 patients were performed 64 - slices spiral CT in coronary artery,the 52 patients underwent selective coronary artery angiography. Results： The main branches and part of the sub - branches of the coronary artery were clearly displayed. 52 coronary artery branches of 30 patients were found stenosis. In 26 cases with conventional angiography,all main branches and parts of sub - branches of coronary artery were displayed clearly. All patients demonstrated coronary artery stenosis . The diagnostic accuracy of 64 -slices spiral CT was 91.62% . Conclusion： As a minimally invasive examination,64 -slices spiral CT should be a valuable method to detect and diagnosed the diseases of coronary artery in type 2 diabetes with tightness in the chest in emergency department.
