To evaluate the use of 4 Fr radial artery catheters as an alternative to both transbrachial and transfemoral approaches.
Seventy examinations were performed via the transradial route using 4 Fr 130-cm-long pigtail catheters. Prior to puncture the radial artery was assessed with pulse oximetry to ensure that it did not contribute the dominant blood supply to the hand. Patients were reassessed for complications within 24 hr of the procedure.
Acceptable images were obtained in femoral arteriography, arch aortography, and selective carotid studies. In three of six renal arteriograms, images were suboptimal. There was a total technical failure rate of 5.7%. Significant complications were encountered in 4.3%, but no hand ischemia occurred.
The transradial route for arteriography is easy to learn and has a low complication rate. It is a reasonable alternative approach to transfemoral arteriography for true outpatient peripheral angiography and in cases where the transfemoral route is not feasible, though it did not prove satisfactory for renal arteriography in hypertensive patients.
评估使用4F桡动脉导管作为经肱动脉和经股动脉途径的替代方法。
使用4F 130厘米长的猪尾导管经桡动脉途径进行了70次检查。穿刺前用脉搏血氧饱和度仪评估桡动脉，以确保其对手部的主要血液供应无贡献。在术后24小时内对患者进行并发症再评估。
在股动脉造影、主动脉弓造影和选择性颈动脉研究中获得了可接受的图像。在6例肾动脉造影中的3例中，图像欠佳。总技术失败率为5.7%。4.3%的患者出现了严重并发症，但未发生手部缺血。
经桡动脉途径进行血管造影易于学习且并发症发生率低。对于真正的门诊外周血管造影以及经股动脉途径不可行的情况，它是经股动脉血管造影的一种合理替代方法，尽管在高血压患者的肾动脉造影中它并不令人满意。
