摘要 目的研究使用改良共用型造影导管经桡动脉径路诊断性冠状动脉造影的可行性和安全性。方法经桡动脉径路冠状动脉造影患者268例,按其造影开始时选用1·67mm(5F)共用型造影导管或1·67mm(5F)改良共用型造影导管而分为共用型导管组(n=133)和改良型导管组(n=135)。对比观察两组手术成功率、X线透视时间和手术操作时间,以及误入分支的发生率。结果共用型导管组133例中116例(87·2%)仅使用共用型导管经桡动脉径路行冠状动脉造影成功,改良型导管组135例中131例(97·0%)仅使用改良型导管经桡动脉径路行冠状动脉造影成功。共用型导管组和改良型导管组相比,造影成功率差异有统计学意义(87·2%比97·0%,P<0·01),平均X线透视时间(28±6min比15±4min)和手术操作时间(56±9min比34±7min)差异均有统计学意义(P均<0·01),误入分支率差异也有统计学意义(11·3%比1·5%,P<0·01)。结论使用改良型造影导管经桡动脉径路诊断性冠状动脉造影比常用的共用型造影导管可明显提高造影成功率,缩短X线透视时间和手术操作时间,减少导管误入分支率。随着改良型导管的使用更加普及,其对提高手术操作的成功率以及安全性的影响将日益重要。 Objective To study the feasibility and safety of the diagnostic coronary angiography by transradial approach with modified 5 F universial catheter. Methods Retrospective analysis was performed in 268 randomly chosen patients undergoing diagnostic coronary angiography by transradial approach, either with 5 F universial catheter (universial group,n = 133) or 5 F modified universial catheter (modified group, n = 135 ). The success rate and the duration of operation and fluoroscopy, the rate of error entry into branch vessel between the 2 groups were compared. Results The success rate for angiography was 87.2% ( 116/ 133 ) in the universal group and 97. 0% ( 131/135 ) in the improved group (P 〈 0. 01 ). The mean duration of operation and fluoroscopy in the universial group was 56 ±9 min and 28±6 min, but 34 ±7 min and 15 ± 4 min in the modified group. There were significant differences between groups ( P 〈 0.01 ). There were significant differences in the rate of error entry into branch Vessel between the universial group and the modified group ( 11.3% vs 1.5%, P 〈 0. 01 ). Conclusion ( 1 ) The procedural success rate of the modified group is higher than that of the universial group. (2) The average duration of operation and fluoroscopy in the modified group was shorter than that of the universial group, but the rate of error entry into branch vessel was lower in the modified group. Application of the modified 5 F universial catheter can enhance the safety and success rate of coronary angiography by transradial approach.
