改良冠状动脉造影术的临床应用

Clinical Application of Modified Coronary Angiography

目的：评价改良冠状动脉造影术的临床应用优势及安全性。方法：我院2003-04～2005-06住院行冠状动脉造影340例。随机分为改良冠状动脉造影组170例（未用三联三通，简称改良组）和常规冠状动脉造影组170例（用三联三通，简称常规组）。比较两组X线照射时间，手术操作时间、手术成功率、冠状动脉并发症（冠状动脉痉挛、导管嵌顿阻塞冠脉开口）、材料费用。结果：两组患者X线照射时间分别为（4．62±3．05）min和（5，28±3．26）min（P〈0．05）；手术操作时问分别为（12．23±8．45）min和（19，46±9．21）min（P〈0．01）；手术成功率均为100％（P〉0．05）；冠状动脉并发症分别为3例和2例（P〉1．05）；材料费用分别为（1146.35±166．56）元和（1546．35±186．84）元（P〈0．05）。结论：改良冠状动脉造影术和常规冠状动脉造影术一样安全，有效和可行。且比常规组节省费用、减少X线照射时间和手术操作时间。

Objective：To evaluate the advantages and safety of modified coronary angiography. Methods：340 cases ,admitted from April, 2003 to June, 2005 and received coronary angiography,were randomized to modified coronary angiography groups（Group A ,n=170） vs regular coronary angiography（Group B,n= 170）. The duration of exposure to X-ray,the procedure time ,the success rate ,the complication related to coronary artery and cost were compared. Results ： It was showed that exposure time to X-ray was （4.62±3.05） min and （5.28±3.26） min（P〈0.05）,the procedure time was （12.23±68.45） mln and （19.46±9.21） min（P〈0. 01） ,the success rate were both 100% （P〉0. 05） ,the complication was 3 and 2 cases （P〉0.05） and cost was （l 146.35±166.56） yuan and （1 546.35±186.84） yuan in Group A and Group B（P〈0.05）. Conclusion：Two methods are similarly safe and feasible,but the cost,exsposure time to X-ray and duration of procedure are Zess in those with modified method.
