Application of rotational DSA in diagnosis and treatment of chronic complete occlusive disease of coronary artery

目的观察旋转DSA技术在冠状动脉慢性完全闭塞性病变诊治中的应用价值。方法选取延安大学附属医院2015-01~2017-01就诊的冠状动脉慢性完全闭塞性病变患者100人,随机分为观察组与对照组,观察组采用旋转DSA技术进行冠状动脉慢性完全闭塞性病变诊治,对照组采用常规DSA造影技术进行诊治,比较两组成像质量及检测出左、右冠状动脉中段完全性闭塞的例数。结果应用旋转DSA技术诊治冠状动脉慢性完全闭塞性病变,可避免血管的重叠,能显示最佳的角度、分叉处的病变及冠脉血管的全貌,可观察冠脉血管的整体形态。对诊治冠状动脉慢性完全闭塞性病变有很大的价值。结论旋转DSA技术在冠状动脉慢性完全闭塞性病变诊治过程中具有空间分辨率与图像分辨率较高的特点,可提供准确的病变信息,对介入手术的成功具有较大的帮助。

Objective To observe the value of rotating DSA in the diagnosis and treatment of chronic complete occlusive disease of coronary artery. Methods 100 patients with chronic complete occlusive disease were randomly selected from February 2015 to January 2017 in affiliated hospital of Yan＇an university. The patients were randomly divided into observation group and control group. The observation group was treated by rotating DSA technique for the diagnosis and treatment of chronic complete occlusive disease of coronary artery. The control group was treated with conventional DSA imaging technique. The imaging quality of the two groups was compared and the number of complete occlusion in the left and right coronary arteries was detected. Results Application of rotating DSA technique in the diagnosis and treatment of coronary artery complete occlusive lesions. It can avoid the overlap of blood vessels,show the best angle,bifurcation lesions and the whole picture of coronary artery and observe the overall shape of coronary artery. This diagnosis and treatment of coronary artery chronic complete occlusive lesions have great value.Conclusion It has been proved that rotating DSA has the characteristics of spatial resolution and high image resolution in the diagnosis and treatment of chronic complete occlusive disease of coronary artery,which can provide accurate information and has great help to the success of interventional surgery.
