MDCT冠状动脉造影的临床应用价值分析及护理

The application and nursing of MDCT coronary arteriongraphy

目的探讨MDCT冠状动脉造影检查技术的临床应用价值及护理体会。方法55例冠心病的患者均同时行MDCT冠状动脉造影检查（CTCA）和DSA选择性冠状动脉造影检查（SCA），用GE Advantange Workstation A W4．3影像后处理工作站对采集的CTCA原始数据信息结果进行影像图像后处理，重建出冠状动脉影像，并以SCA为金标准分析CTCA的检查结果。结果55例患者行CTCA检查显示冠状动脉左前降支、左回旋支及右冠状动脉的显示率分别为100％（55／55）、95．2％（51／55）和98．4％（54／55），CTCA诊断冠状动脉狭窄〉50％的敏感度93．5％、特异度95．3％、准确度94．6％。结论MDCT冠状动脉CTA检查结果和SCA检查结果有较高的一致性，是临床上一种筛选冠状动脉病变的良好方法。

Objective To investigate the application and nursing of MDCT coronary arteriongraphy. Methods A total of 55 coronary heart disease patients were treated with MDCT coronary arteriongraphy （CTCA） and DSA selective coronary arteriongraphy （SCA）. The GE Adw 4. 3 after treatment working station of an image was used for collection CTCA original data results and reconstruction an image of coronary artery , and CTCA inspection results were analyzed by SCA golden standard. Results The display rate of left anterior descending branch, left circumflex, fight coronary artery by CTCA inspection was 100% （55/55）, 95.2% （51/55） and 98.4% （54/55）, respectively. The susceptibility, specificity, accuracy of CTCA diagnosis coronary artery narrow 〉 50 was 93.5%, 95.3% , 94. 6%, respective- ly. Conclusions The results of CTCA and SCA have higher consistency as a result, and CTCA is a good method of selection pathological changes of coronary artery.
