Objective : To get experiences of coronary angioplasty via the radial artery on Chinese population and evaluate its safety and possibility- Methods : Fifty one out of63 patients were selected from June 1998 to February 1999 to be undertaken ad hoc coronary angioplasty via the radial artery in Zhong zhan Hospital,Shanghai- The average age ofthese patients was 60-0 ±9-5 (40 ～80) , male patients were 46 ,female patients were 5- The right radial arteries were preferred to perform coronary angioplasty with Judkins technique- The inner diameters and average blood velocity of the right radial artery wwere measured with color Doppler echocardiogram in 33 patients and after coronary angioplasty- Results : Before coronary angioplasty ,the diameters of the right radial artery were 0-18 ～0-37 cm (0-260 ±0-046 cm) ,the average blood velocities were 23 ～98 cm/s (54-16 ±19-45 cm/s)- After coronary angioplasty ,the diameters of the right radial artery were 0-21 ～0-39 cm (0-250 ±0-031 cm) ,the average blood velocities were 22-4 ～100 cm/s (52-79 ±28-36 cm/s) ,the differences ofthe diameters ofthe rightradial artery as well as the average blood velocities between before coronary angioplasty and after coronary angioplasty were insignificant ( p > 0-05)- Balloon angioplasty was performed in 71 lesions (30 type A,17 type B,and 24 type C)- 51 stents were implanted in 51 lesions (25 type A,14 type B,and 12 type C)- Among the 51 stents the shortest was 9 m m ,the longest was 40 m m ,the smallest in diameter was 2-5 m m ,the biggest in diameter was 3-5 m m- Procedural success was achieved in 47 patients (92-2 % )- In 4 patient ,the guide wires could not be delivered to the distal segments of the diseased coronary arteries due to chronic occlusion in LAD- Access related complications and occlusion of right radial arteries were notfound during hospital stay- Only in one patient,the guiding catheter resulted in nonfatal non Q wave myocardial infarction- Conclusion : Transradial angioplasty and
目的分析经桡动脉对冠状动脉慢性闭塞性(CTO)病变进行介入治疗的可行性、临床效果和手术成功的影响因素。方法回顾2003年1月至2006年6月首都医科大学附属北京安贞医院心内科156例患者187处CTO病变经桡动脉行介入治疗的资料。分析开通组(135处病变)和未开通组(52处病变)的临床、介入影像特征、器械应用、主要并发症等情况。结果187处CTO病变中135处病变经桡动脉成功开通,52处病变未能开通,成功率72%;两组临床特征、病变血管位置、直径差异无统计学意义。开通组与未开通组病变形态、长度、时间差异均有统计学意义(P<0.05):锥形病变71%对52%,平齐病变29%对48%。钙化病变14%对40%,桥侧支12%对35%,闭塞时间(5.2±4.3)个月对(9.2±5.4)个月。病变长度≤15 mm 87%对15%,病变长度>15 mm13%对85%。失败原因主要是导引钢丝或球囊未能通过病变部位。多元分析显示CTO持续时间是影响开通率最重要的因素。术后发生前臂血肿1例,桡动脉闭塞1例,未见其他严重并发症。结论经桡动脉介入治疗CTO病变安全可行,成功率较高,无严重并发症。
