We investigated the prevalence and clinical predictors of severe tortuosity of the right subclavian artery (RSA) in 2,341 consecutive patients who underwent transradial coronary angiography as well as the feasibility and safety of a technique to complete transradial catheterization. Severe tortuosity of the RSA was seen in approximately 10% of these patients, and clinical predictors included systemic hypertension, female gender, older age, nonsmoker, short stature, and high body mass index. Guidewire replacement with a stiff guidewire is reliable and safe for completing transradial angiography in most patients with a tortuous RSA.
我们对2341例连续接受经桡动脉冠状动脉造影的患者进行了研究，以探讨右锁骨下动脉（RSA）严重迂曲的患病率和临床预测因素，以及完成经桡动脉导管插入术的技术的可行性和安全性。在这些患者中，约10%可见RSA严重迂曲，临床预测因素包括系统性高血压、女性、年龄较大、不吸烟、身材矮小和高体重指数。对于大多数RSA迂曲的患者，用硬导丝更换导丝在完成经桡动脉血管造影方面是可靠且安全的。
