经桡动脉冠状动脉介入手术对桡动脉及血流速度的影响

The Effects of Transradial Coronary Interventional Procedures on Diameters and Blood Vetocities of Radial Artery

目的 :评价经桡动脉介入手术对桡动脉的影响。方法 :选择 10 9例经桡动脉冠状动脉造影或冠状动脉腔内成形术 (PT CA)患者 ,其中男性 91例 ,女性 18例 ,年龄 37～ 81岁 (平均 6 6 .8± 8.9岁 )。分别于术前及术后采用彩色多普勒超声测量桡动脉直径和血流速度的变化 ,并同时分别于术前及术后在压迫和不压迫桡动脉情况下 ,测量尺动脉直径和血流速度的变化。结果 :经桡动脉介入手术前后桡动脉直径和血流速度无明显变化 (P >0 .0 5 ) ,术后未见血肿、动脉瘤、动静脉瘘及桡动脉闭塞发生。结论 :在Allen试验阴性的患者中 ,采用经桡动脉介入手术安全、可行 ,不会造成手部缺血。桡动脉也可作为冠脉介入的入径反复使用。

Objective: To evaluate effects of interventional procedure on radial artery. Methods: 109 patients, including ninety-nine male and eighteen female patients with average ages of 66.8±8.9(37～81), were undertaken transradial coronary angiography or percutaneous transluminal coronary angioplasty. Diameters and blood velocities of the radial artery, as well as the ulnar artery with and without pressing the radial artery, were measured with color Doppler ultrasound before and after the procedure. Results: There were no significant changes of diameters and blood velocities of the radial artery after interventional procedure ( P >0.05). No hemotoma, no aneurysm, arteriovenous fistulas and occlusion of the radial artery were observed after interventional procedure. Conclusions: Transradial access is a safe and practical alternative approach for interventional procedure, it can be reused.
