In coronary angiography there is a trend toward using smaller catheters to avoid puncture site complications. An increased utilization of outpatient facilities may result. This study was undertaken to determine whether using 4Fr diagnostic catheters in comparison with 5Fr catheters would reduce the vascular complication rate, after patient ambulation following 4 h bedrest, without altered technical performance and or procedural duration.
The study population comprised 100 consecutive, unselected patients, who were randomly assigned for transfemoral coronary angiography with 4 or 5Fr diagnostic catheters. Procedural characteristics, quality of angiogram, and clinical assessment of puncture site at 4, 12, and 24 h were analyzed.
No significant difference was demonstrated concerning procedural characteristics, ventriculography, coronary contrast quality, or local vascular damage. However, two patients crossed over in the 4Fr group and one in the 5Fr group.
As a consequence, the feasibility, reliability, and utility of catheter size on vascular complication rates must be considered to be similar with either 4Fr or 5Fr diagnostic catheters.
在冠状动脉造影术中，存在使用更细导管以避免穿刺部位并发症的趋势。这可能导致门诊设施的利用率增加。本研究旨在确定在卧床休息4小时后患者下床活动的情况下，与5Fr导管相比，使用4Fr诊断导管是否会降低血管并发症发生率，同时不改变技术性能和手术时长。
研究人群包括100例连续入选的未选择患者，他们被随机分配接受经股动脉冠状动脉造影，使用4Fr或5Fr诊断导管。分析了手术特征、血管造影质量以及在4小时、12小时和24小时时穿刺部位的临床评估情况。
在手术特征、心室造影、冠状动脉造影质量或局部血管损伤方面未显示出显著差异。然而，4Fr组有两名患者交叉，5Fr组有一名患者交叉。
因此，4Fr或5Fr诊断导管在血管并发症发生率方面的可行性、可靠性和实用性必须被视为相似。
