The transradial approach has become the preferred route for performing coronary angiography and interventions. Several studies reported that radial access is associated with significant reduction in vascular complications compared with the femoral access. This technique allows also early ambulation, improves the patient's well-being, and is less expensive. One important limitation of radial access is that coronary engagement from transradial approach is more challenging than transfemoral approach. The increased susceptibility of the radial artery to spasm, the radial-brachial artery tortuosities, and the subclavian-aorta curves make catheter advancement and coronary artery cannulation difficult. Hereby, we suggest several techniques for recognising and overcoming potential challenges during transradial coronary angiography.
经桡动脉入路已成为进行冠状动脉造影和介入治疗的首选途径。多项研究表明，与股动脉入路相比，桡动脉入路与血管并发症的显著减少相关。该技术还允许早期活动，改善患者的舒适度，并且成本更低。经桡动脉入路的一个重要局限性是，与经股动脉入路相比，经桡动脉入路进行冠状动脉造影更具挑战性。桡动脉对痉挛的敏感性增加、桡动脉-肱动脉迂曲以及锁骨下动脉-主动脉弯曲使得导管推进和冠状动脉插管困难。在此，我们提出了几种技术，用于识别和克服经桡动脉冠状动脉造影过程中的潜在挑战。
